WhiteboxTools - WhiteboxTools Open Core v2.3.0

Note: Compiled binaries for Windows, macOS, and Linux can be found at: https://www.whiteboxgeo.com/download-whiteboxtools/

Release Notes

• Added the new Whitebox Runner v2.0. This version of WbRunner is an entirely new application with many advancements over the previous version of the WbRunner. It is now written in pure Rust (compared with the old Python TkInter app) using the egui user-interface library. It has a more modern feel, is cross-platform, and has no dependencies (including Python). You can now open multiple tools simultaneously.
• WbRunner is now the preferred way now for installing the Whitebox Toolset Extension (WTE).
• Added the LaunchWbRunner and InstallWbExtension tools so that the Whitebox Runner will be more accessible from other Whitebox frontends. This way users will always have a good fall-back if the frontend is not up-to-date with the WBT backend, since WbRunner is always current with the installed version of WBT.
• Added the IndividualTreeDetection tool for identifying points in a LiDAR point cloud that are associated with the tops of individual trees.
• Added the NormalizeLidar tool for normalizing LiDAR point clouds, i.e., converting their z-values from elevation to height-above-ground.
• Natural Resources Canada (NRCan) has sponsored the open-sourcing of two tools contained in the extension, VectorStreamNetworkAnalysis and RepairStreamVectorTopology. These two tools are are now available in the WbT Open Core.
• Fixed a bug with the LidarShift tool. The tool was calculating the shift in transformed coordinates incorrectly leading to very strange outputs.
• The MultiscaleTopographicPositionImage tool now takes an optional hillshade image as input.
• Lowered the peak memory requirement of the D8FlowAccumulation tool.
• Fixed a bug with the location of the settings.json file when running plugin tools, that sometimes led to the file being located in a top-level directory, and therefore sometimes yielding a permissions error when running on systems without admin rights.
• Fixed a bug with the vector attribute table reader that caused issue with the VectorPolygonsToRaster tool.
• Fixed a bugs in the HorizonAngle and ExposureTowardsWindFlux tools.
• Added a point time interpolation parameter to the LidarNearestNeighbourGridding tool.
• Added the ListUniqueValuesRaster tool.
• Fixed a bug with the SetNodataValue tool, where the raster data type is updated to a signed integer if the background value is negative and the input image has an unsigned data type.
• Added a 'mean' option to the VectorPointsToRaster tool.

WhiteboxTools - WhiteboxTools v2.2.0

Note: Compiled binaries for Windows, macOS, and Linux can be found at: https://www.whiteboxgeo.com/download-whiteboxtools/

Release Notes:

• Added the TravellingSalesmanProblem tool for identifying short routes connecting multiple locations.
• Added the HeatMap tool for performing kernel density estimation (KDE) from vector points.
• Added the MultiplyOverlay tool.
• Added the MaxUpslopeValue tool.
• Added the ConditionedLatinHypercube tool for stratified random sampling (credit Dr. Dan Newman).
• Added the HighPassBilateralFilter tool, useful for emphasizing image texture.
• Fixed a bug with the DirectDecorrelationStretch tool.
• Fixed a bug in the automatic install of the Whitebox extensions that affected Windows users.
• Fixed a bug with the persistence of the compress_rasters parameter. Python users were unable to
  turn off the compress flag previously.
• Added the option to set and get the maximum number of processors (--max_procs flag) used by WBT in
  the Whitebox Python API.
• Added the option to output average point density and nominal point spacing to the LidarInfo tool.
• Updated the ClassifyOverlapPoints and FlightlineOverlap tools to use information contained within
  the Point Source ID property, rather than a hard-coded time difference threshold previously used.
• Fixed an issue that affected many tools when input rasters use either NaN or Inf as NoData values.
• Fixed an issue with the way that NoData values are handled during the euclidean distance transform
  that impacted the EuclideanDistance, EuclideanAllocation, BufferRaster, and
  ElevationAboveStreamEuclidean tools.
• Fixed a bug with the LidarInfo tool that occurred when the user did not specify the mandatory
  output parameter along with a non LAS input file.
• Fixed a bug with the Truncate tool; the output image was always integer, and therefore it did not
  work as expected when using more than zero significant digits.
• Fixed a bug with the ConstructVectorTIN tool that resulted in an error when no field data are used.
• Modified the code for writing to the settings.json file so that rather than issuing an error when
  the app doesn't have write permission, it simply prints a warning and carries on.
• Fixed bugs in the Geomorphons tool (submitted by Dr. Dan Newman).
• Fixed a bug with the writing of PolyLineZ vectors.
• Updated the Hillshade, MultidirectionalHillshade, and RelativeAspect tools to use the more robust
  5x5 3rd order bivariate polynomial method of Florinsky (2016) for rectangular grid DEMs, and the
  3x3 method, also described by Florinsky (2016), for DEMs in geographic coordinates. This is a large
  improvement in accuracy for calculating these surface morphology parameters on geographic coordinates
  compared with the 'z-conversion fudge factor' method used previously.
• Added support for Apple Silicon; you can now download WhiteboxTools binaries compiled on an M1 Mac.

WhiteboxTools - WhiteboxTools v2.0.0

The most important feature in this release is the addition of support for reading and writing the LAZ compressed LiDAR format for all of the LiDAR tools in WBT.

• Added the RasterCalculator tool for performing complex mathematical operations on input rasters.
• Added the ConditionalEvaluation tool for performing an if-then-else operation on an input raster.
• Added the EdgeContamination tool to identify grid cells for which the upslope area extends beyond the data extent.
• Added the ExposureTowardsWind tool.
• Added the QuinnFlowAccumulation tool to perform a Quinn et al. (1995) flow accumulation operation.
• Added the QinFlowAccumulation tool to perform a Qin et al. (2007) flow accumulation operation.
• Added the Rho8FlowAccumulation tool to perform a Fairfield and Leymarie (1991) flow accumulation operation.
• LidarHistogram now allows a GPS time parameter, which can be useful for determining the number of flightlines in a LiDAR tile.
• Fixed a bug with the Resample tool that created an artifact when resampling to resolutions less than one meter.
• Fixed a bug that prevented plugin tools from being discovered by the open-core when run from the command line on PATH when the working directory was something other than WBT.
• Fixed several bugs in the ContoursFromPoints tool.
• Fixed the z_factor calculation for large-extent DEMs in geographic coordinates for the geomorphometric shape metric tools, e.g., slope, aspect, hillshade, and curvatures. The new approach calculates a different z_factor conversion value for each row in the raster, rather than using a single value based on the raster mid-point latitude. This should help improve the accuracy of these shape indices on large-extent rasters in geographic coordinate systems.
• Fixed several bugs in the Isobasins and D8FlowAccumulation tool.
• The NewRasterFromBase tool now accepts a vector base file (and grid cell size) as well as a raster.
• The WhiteboxTools User Manual has had a refresh and is now hosted at: https://www.whiteboxgeo.com/manual/wbt_book/intro.html.
• We have added numerous tools to the WhiteboxTools Extensions.

WhiteboxTools - WhiteboxTools v1.5.0

Version 1.5.0 (31-05-2021)

• This release does not include very many new tools. Despite this, this is probably one of the largest
  releases yet. We have made extensive changes to the codebase, improving functionality in many
  significant ways. Therefore, we're very excited to announce the release of v1.5.
• Probably the most exciting change is the introduction of plugin tools. Up until now, WBT has had a
  monolithic architecture, where all of the tools live within a single binary. This architecture has
  provided a number of benefits up until now. However, as the number of tools in WBT grows, it becomes
  increasingly difficult to maintain this program structure - in particular, compile times have grown
  significantly since the projects start. A plugin architecture provides much greater flexibility in
  this regard. Single tool plugins can be created, placed within the new 'plugins' folder within the
  WBT directory, and the whitebox_tools.exe binary will treat these plugins like any other tool within
  the monolith. This also means that WBT users can develop their own custom tools, without the required
  know-how of figuring out how to integrate their tool into the large WBT code-base. The user manual
  will be updated shortly to describe how this process works. For now, there is only one plugin tool
  example in the open-core (SplitVectorLines) although several other plugins have been developed (more
  on this below). The one downside of the new plugin architecture is that the size of the WBT download
  will inevitably grow, as individual tool executables will be larger than the single monolith. We
  believe that this is an acceptable compromise.
• In order to accommodate plugin tools, we have significantly changed the codebase. Most significantly
  We have pulled the code associated with low-level functions, the so-called 'plumbing' code, (e.g.
  code for reading and writing various data files) into separate sub-repositories. In this way, the
  tools in the monolith and the plugin tools can both use this code without duplication.
• WBT now has persistent environment variables contained within a 'settings.json' file within the WBT
  folder. Currently, these settings including 'verbose_mode', 'working_directory', 'compress_rasters',
  and 'max_procs'. More environment variables may be added in later releases. The fact that verbose mode
  the working directory, and the compress_rasters flag are now persistent does have implications for the
  Python and R front-ends and for the way these settings are used. The user manual will be updated
  shortly to reflect these changes.
• We introduced the 'max_procs' setting. Now, all tools that run in parallel, or partially parallelize,
  can be restricted to a maximum number of processes. Before, WBT would simply use all of the available
  cores in the machine it was running on. While this is still the default (max_procs: -1), there are
  certain conditions where this behaviour is undesirable. For example, when WBT is run on large servers
  or cloud-computing environments where a great many cores are shared among many users, it can be
  problematic when a single user/program consumes all of the available cores. This setting limits
  the maximum number of procs.
• Added the EmbankmentMapping tool for mapping transportation embankments (road, rail) in LiDAR DEMs.
• Added the SplitVectorLines tool. This tool will parse an input line vector into a series of segments
  of a specified length. It is also an example of a WBT plugin.
• The code has been updated to reflect the new zLidar v1.1 specification, which has significantly improved
  compression rates (testing shows it is between 91% and 109% of LAZ), greater flexibility (users may
  specify the degree of compression versus speed of reading/writing), and numerous bug fixes. The zLidar
  specification webpage will soon be updated to reflect the new version. Further news on this front,
  it has come to our attention recently that there is now a Rust-based LAZ encoder/decoder, which provides
  an opportunity for us to add LAZ support in a future version of WBT. We are currently evaluating this
  as an option.
• We are trying to be more engaging with the WBT user community. In this regard, we have set up a new
  Google Groups forum for user to ask questions (https://groups.google.com/g/whiteboxtools), and have a
  new Twitter account (@whiteboxgeo) and newsletter to make announcements. Feel free to sign up for
  either if you're interested in staying in touch.
• Lastly, we are very pleased to announce the creation of WhiteboxTools Geospatial Inc., a new company
  based on providing extension services around the open-source WBT platform. It is our vision that this
  company will provide a way of making the ongoing development of the WBT open-core more sustainable in
  the future, by enabling developers to work full-time on the project. Please read my 'open letter to the
  WBT community' (https://www.whiteboxgeo.com/open-letter-whiteboxtools-community/) for more details
  about this exciting development. Our plan is to maintain, and continue development of, the open-core of
  WBT, while providing plugin extensions that enhance the core capabilities. To begin with, we are launching
  the Whitebox General Toolset Extension, a set of (currently) 19 tools to help GIS professionals with their
  everyday workflows. Please see the newly redesigned WBT webpage at www.whiteboxgeo.com for more details.
  If you have been interested in supporting the WBT project in the past and haven't known how, buying a
  license for the General Toolset Extension is a wonderful way of doing so.

WhiteboxTools - WhiteboxTools v1.4.0

This release add some new tools and several bug fixes. Of the new tools, we are most excited about the addition of the TimeInDaylight tool, which estimates the proportion of daytime that each cell in a digital surface model (DSM) is in an exposed area. This is a very powerful method of performing a basic solar radiation modelling workflow. The new LidarDigitalSurfaceModel tool can be used to create DSMs for input to the TimeInDaylight tool. In addition to these updates, the User Manual has also been updated in numerous places with enhanced documentation. As always, if you wish to compile from source code, be sure to update to the most recent version of Rust beforehand using rustup update stable. Pre-compiled binaries are available for Windows (win), MacOS (Darwin), and Linux on Github and from the WhiteboxTools homepage. Please report any bugs that you encounter by creating an issue on the WhiteboxTools Github site.

• Added the TimeInDaylight model tool for modelling the proportion of daytime that a location is not in shadow.
• Added the MapOffTerrainObjects tool.
• Added the FilterRasterFeaturesByArea tool.
• Added the LidarDigitalSurfaceModel tool.
• The D8 and FD8 flow pointer tools now output byte rasters.
• The Isobasins tool now optionally outputs an upstream/downstream connections table.
• The HorizonAngle tool has had significant performance improvements.
• Improvements to the RemoveOffTerrainObjects tool's performance.
• The Resample tool has been modified so that it does not require a 'destination' raster. Instead,
  it will create a new output raster either based on a user-specified target cell resolution or
  an optional base raster, much like the vector-to-raster conversion tools.
• Tools that input a z_factor conversion no longer override user input with geographic coordinates
  (see issue #113).
• The StreamLinkIdentifier tool now outputs a 32-bit integer format, increasing the maximum allowable
  number of streams (see issue #110).
• Fixed a bug with cubic-convolution and bilinear resampling in the Mosaic tool (see issue #109).

WhiteboxTools - WhiteboxTools v1.3.1

This release adds a few new tools, including two options for creating more advanced hillshade images from DEMs, and better raster file support. This includes critical fixes for the WBT GeoTIFF reader/writer and added support for reading BIL files.

• Added the HypsometricallyTintedHillshade tool to create hypsometric tinted hillshades.
• Added the MultidirectionalHillshade tool.
• Added the ability to read/write in the Esri BIL raster format.
• Added the LidarRooftopAnalysis tool.
• The MultiPartToSinglePart tool now handles MultiPoint vectors.
• Fixed a bug with the VoronoiDiagram to better handle MultiPoint vectors.
• Fixed an issue with writing compressed RGB GeoTIFFs.
• Fixed an issue reading LZW compressed GeoTIFFs.

WhiteboxTools - WhiteboxTools v1.3.0

• Tools will now output DEFLATE compressed GeoTIFFs when the --compress_rasters parameter is used.
• Added support for a newly developed compressed LiDAR data format, the ZLidar file. All tools
  that accepted LAS file inputs and produced LAS outputs can now use '*.zlidar' files as well. I
  have also added the LasToZlidar and ZlidarToLas tools to perform conversions. While the ZLidar
  format does not yield compression rates quite as good as the popular LAZ file format, you can
  expect ZLidar files to be between 20-30% of the size of the equivalent LAS file. A file
  specification will be published in the near future to describe the open ZLidar data format.
• Added the AsciiToLas tool.
• Added the ContoursFromRaster tool for creating a vector contour coverage from a raster surface model (DEM).
• Added the ContoursFromPoints tool for creating a vector contour coverage from vector points.
• Added the UpdateNodataCells tool.
• Modified the Slope tool to optionally output in degrees, radians, or percent gradient.
• Modified the Mosaic tool, which now runs much faster with large numbers of input tiles.
• The vector-to-raster conversion tools now preserve input projections.
• Fixed a bug in the RasterToVectorPolygons tool.
• Fixed several bugs in the MergeTableWithCsv tool.
• Modified the FillMissingData tool to allow for the exclusion of edge-connected NoData cells from the operation.
  This is better for irregular shaped DEMs that have large areas of NoData surrounding the valid data.
• The LidarConstructVectorTin tool has been depreciated. The tool was not creating the proper output.
  Furthermore, since the number of points in the average LiDAR tile is usually many million, this tool
  would usually produce Shapefiles that exceed the maximum allowable number of shape geometries. If
  a vector TIN is required for a LiDAR point set, users should convert the file to a Shapefile and then
  use the ConstructVectorTin tool instead. And of course, if you are interested in a raster TIN from a
  LiDAR file, use the LidarTinGridding tool instead.
• FlattenLakes now handles multipart lake polygons.

WhiteboxTools - WhiteboxTools v1.2.0

• Added the RasterToVectorPolygons tool, which now completes the raster-vector conversion tool set.
• Added the MultiscaleElevationPercentile tool.
• Added the AttributeCorrelationNeighbourhoodAnalysis tool.
• Added the RadialBasisFunctionInterpolation tool, which includes a thin-plate spline mode.
• Added the RasterPerimeter tool to measure the perimeter of raster polygons.
• Added the MDInfFlowAccumulation tool to perform the MD-infinity flow accumulation of Seibert
  and McGlynn (2007).
• Added the InsertDams tool, which can be used to insert impoundment features at a set of points
  of interest into a DEM. This tool can be used in combination with the ImpoundmentSizeIndex tool
  to create artificial reservoirs/depressions.
• Added the HeightAboveGround tool, to normalize a LiDAR point cloud. Each point's z-value is
  converted to the height above the nearest ground-classified point.
• Modified the LidarRbfInterpolation tool to improve efficiency.
• Fixed an issue with how floating point attributes were written in Shapefile attribute tables.
• Updated the LidarSegmentation tool, which now used RANSAC to fit planar models to points.
• Fixed an issue with the Reclass and ReclassFromFile tool that caused striping.
• The Relcass and ReclassFromFile tools now take 'min' and 'max' in the reclass string.
• The watershed tool now accepts either a set of vector points or a raster for the pour points
  file. If a raster is specified, all non-zero, non-NoData valued cells will be considered
  outlet cells and the watershed labels will be assigned based on these values.
• The D8 and D-infinity flow accumulation tools now take either an input DEM or a flow pointer raster
  as inputs.

WhiteboxTools - WhiteboxTools v1.1.0

• Added the BreachDepressionsLeastCost tool, which performs a modified form of the Lindsay
  and Dhun (2015) impact minimizing breaching algorithm. This modified algorithm is very
  efficient and can provide an excellent method for creating depressionless DEMs from large
  DEMs, including those derived from LiDAR. It is particularly well suited to breaching
  through road embankments, approximately the pathway of culverts.
• The FillDepressions tool algorithm has been completely re-developed. The new algorithm is
  significantly faster than the previous method, which was based on the Wang and Lui method.
  For legacy reasons, the previous tool has been retained and renamed FillDepressonsWangAndLui.
  Notice that this new method also incorporates significantly improved flat area correction
  that maintains general flowpaths of filled areas.
• The Sink and DepthInSink tools have been updated to use the new depression filling algorithm.
• Added the ClassifyBuildingsInLidar tool to reclassify LiDAR points within a LAS file
  to the building class value (6) that are located within one or more building footprint
  contained in an input polygon vector file.
• Added the NaturalNeighbourInterpolation tool for performing Sibson's (1981) interpolation
  method on input point data.
• Added the UpslopeDepressionStorage tool to estimate the average upslope depression
  storage capacity (DSC).
• Added the LidarRfbInterpolation tool for performing a radial basis function interpolation
  of LiDAR data sets.
• The WhiteboxTools Runner user interface has been significantly improved (many thanks to
  Rachel Broders for these contributions).
• Fixed a bug in which the photometric interpretation was not being set by certain raster
  decoders, including the SAGA encoder. This was causing an error when outputting GeoTIFF
  files.
• Updated the ConstructVectorTIN and TINGridding tools to include a maximum triangle edge
  length to help avoid the creation of spurious long and narrow triangles in convex regions
  along the data boundaries.
• Added the ImageCorrelationNeighbourhoodAnalysis tool for performing correlation analysis
  between two input rasters within roving search windows. The tool can be used to perform
  Pearson's r, Spearman's Rho, or Kendall's Tau-b correlations.

• Added a Wilcoxon Signed-Rank test (WilcoxonSignedRankTest) for comparing two rasters.
• Added a paired-samples Student's t-test (PairedSampleTTest) for comparing two rasters.
• Added the inverse hyperbolic trig functions, i.e. the Arcosh, Arsinh, and Artanh tools.
• Renamed the LeeFilter to the LeeSigmaFilter.
• Renamed the RelativeStreamPowerIndex tool to StreamPowerIndex, to be more in-line with
  other software.
• Fixed another bug related to the handling of Boolean tool parameters.

Natural Resources - Water Supply and Quality - Rust
Published by jblindsay over 5 years ago

WhiteboxTools - WhiteboxTools v1.0.1

This is a bug-fix release. It includes the following changes:

• Boolean type tool parameters previously worked simply by their presence in the parameter list. That is, simply have --flag in the list set the value of flag to True while its absence set it to False. This was causing problems with some WBT front-ends, particularly the QGIS front-end, where the parameters were being provided to WBT as --flag=False. In this case, because the flag was present, it was assumed to be True. All tools that have Boolean parameters have been updated to handle the case of --flag=False. This is a widespread modification that should fix the unexpected behaviour of many tools in certain front-ends. Because this represents a significant modification to the behaviour of numerous tools, it was decided that this minor release was warranted.
• Fixed a minor bug with the VectorPolygonToRaster tool.
• Fixed a bug in the DownstreamDistanceToStream tool.

WhiteboxTools - WhiteboxTools v1.0.0

We are very pleased to announce the release of WhiteboxTools v1.0.0. This milestone release contains numerous feature additions and bug fixes and marks a period of stabilization in the platform. Modifications include the following:

• Added support for reading and writing the BigTIFF format. This has resulted in numerous changes
  throughout the codebase as a result of significant modification of ByteOrderReader and addition
  of ByteOrderWriter. This change has touched almost every one of the raster format
  encoders/decoders.
• Performance improvements have been made to the FlattenLakes (hydro-flattening) tool.
• Fixed a bug preventing the SplitColourComposite tool from reading the '--input' flag correctly.
• The ClipLidarToPolygon now issues a warning if the output LAS file does not contain any points
  within the clipped region and does not output a file. Also, the LAS reader no longer panics
  when it encounters a file with no points. Now it reads the header file, issues a warning, and
  carries on, allowing the tools to handle the case of no points.
• ImageRegression can now optionally output a scatterplot. The scatterplot is based on a random
  sample of a user-defined size.
• Added the CleanVector tool.
• ExtractRasterStatistics has been renamed ZonalStatistics to be more inline with other GIS,
  including ArcGIS and QGIS.
• Added the median as a statistic that ZonalStatistics provides.
• Fixed a bug in the VectorPolygonsToRaster tool that sometimes mishandled polygon holes.
• Added the FilterLidarClasses tool to filter out points of user-specified classes.
• Added the LidarRansacPlanes tool to identify points belonging to planar surfaces. This tool
  uses the RANSAC method, which is a robust modelling method that handles the presence of
  numerous outlier points.
• The ClipLidarToPolygon tool has been parallelized for improved performance.
• The LasToAscii and AsciiToLas tools have been updated to handle RGB colour data for points.
• Added the CsvPointsToVector tool to convert a CSV text table into a shapefile of vector points.
  The table must contain x and y coordinate fields.
• The FeaturePreservingDenoise was renamed to FeaturePreservingSmoothing. The DrainagePreservingSmoothing
  tool was removed. Use FeaturePreservingSmoothing instead.
• Added the ability to output the average number of point returns per pulse in the LidarPointStats tool.
• LidarTinGridding, LidarIdwIntarpolation, and LidarNearestNeighbourGridding now can interpolate the
  return number, number of returns, and RGB colour data associated with points in a LAS file.
• Added the ModifyNoDataValue tool to change the NoData value in a raster. It updates the value in
  the raster header and then modifies each grid cell in the raster containing the old NoData value
  to the new value. This operation overwrites the existing raster.
• Fixed an issue with GeoTIFF NoData values that impacted many tools. NoData values were not interpreted
  correctly when they were very large positive or negative values (near the min/max of an f32).

WhiteboxTools - WhiteboxTools v0.16.0

Version 0.16.0 (24-05-2019)

• Added the MergeLineSegments and SphericalStdDevOfNormals tools.
• Fixed a bug with reading LAS files with point records with extra bytes. Previously, the LAS decoder
  assumed the Point Record Length matched that of the LAS specifications (with the variable of the
  optional intensity and user data). Some LAS files in the wild (particularly those created using
  LASTools and of LAS version 1.2) have larger Point Record Lengths, which presumably carry extra
  bytes of information. These extra byes are ignored, but they no longer throw off the decoding.
• Fixed a bug with writing Big-Ending GeoTIFF files. The 'MM' file header was not correct previously.
• Significantly reduced the memory requirements of the StochasticDepressionAnalysis tool. The tool
  may be somewhat slower as a result, but it should be applicable to larger DEMs than was previously
  possible.
• Fixed bugs with the Union and SplitWithLines tools.
• WhiteboxTools can now read and write Shapefiles of MultiPointZ, PolyLineZ, and PolygonZ ShapeTypes
  missing the optional 'M' values (i.e. measures).
• SelectTilesByPolygon and LidarTileFootprint are now compatible with LAZ file inputs. Both of these
  tools only rely on information in the input LiDAR file's header, which is the same for a LAZ file
  as a LAS file.
• Fixed a bug with writing Saga GIS files (*.sdat) that inverted rasters.

WhiteboxTools - WhiteboxTools v0.15.0

Version 0.15.0 (03-03-2019)

• The following tools were added to the project:
  BoundaryShapeComplexity
  NarrownessIndex
  ShapeComplexityIndexRaster

• Fixed a bug with the PanchromaticSharpening tool.

• Previously, if a LAS v1.4 file were input to a tool, the output LAS file, which is currently
  always in LAS v1.3 format, would not correctly translate the 64-bit information (point
  return, number of returns, classification) into 32-bit format. I have added the
  get_32bit_from_64bit function to handle this translation more gracefully; albeit it is
  still a lossy translation where returns greater than 5 are ignored and classification
  values greater than 31 are lost.

• Added a maximum triangle edge length parameter to the LidarTinGridding tool to allow
  for the exclusion of large-area triangles (i.e. low point density) from the gridding.

• The NormalizedDifferenceVegetationIndex tool has been renamed to NormalizedDifferenceIndex
  to indicate the more general nature of this tool (i.e. NDVI, NDWI, OSAVI, etc.).

• Significant changes have been made to the BreachDepressions tool to make it more in-line
  with the behaviour of the GoSpatial algorithm described in the original Lindsay (2016)
  paper. These changes include: 1) the inclusion of an optional parameter to fill single-cell
  pits prior to breaching, 2) the addition of a --flat_increment parameter, which overrides
  the automatically derived value assigned to flat areas along breach channels (or filled
  depressions), and 3) the tool now performs a fast post-breach filling operation, when
  run in constrained-breaching mode (i.e. when the user specifies values for either
  --max_depth or --max_length, placing constraints on the allowable breach channel size).

  interpreted as geographic coordinates, thereby messing up the calculation of
  inter-cell distances for tools like slope, aspect, curvature, etc.
• Fixed a bug with several of the math tools; output files took their data type
  from the input file. In some cases, this does not work well because the input
  is integer and the output must be floating point data.

WhiteboxTools - WhiteboxTools v0.13

• The release largely focusses on bug-fixes rather than adding new features. The
  following tools were added to the project:
  MosaicWithFeathering
• Support was added for GeoTIFF MODELTRANSFORMATIONTAG (Tag 33920).
• Support was added for reading GeoTIFFs that have coordinate transformations
  defined by multiple tiepoints contained with the ModelTiepointTag (Tag 33922).
  These rasters have their raster-to-model transform defined by a 2D polynomial
  regression of the 3rd order.
• The initialize_using_file function in the abstract Raster model now transfers
  information contained in an input GeoTIFF's ModelTiePoint, ModelPixelScale,
  ModelTransform, GeoKeyDirectory, GeoDoubleParms, and GeoAsciiParams tags to
  the output raster. This means that if a GeoTIFF file is input to a Whitebox
  tool, and the output raster is specified to be of GeoTIFF format as well,
  all of the coordinate information contain in the input raster will now be
  contained in the output raster.
• The FeaturePreservingDenoise and DrainagePreservingSmoothing tools, both of
  which are used for DEM generalization, now represent surface normal vectors
  using 32-bit floats instead of the original double-precision values. This
  does not alter the results of these tools significantly, but does reduce the
  memory requirements and run-times of these tools substantially.
• The LidarKappa tool now outputs a raster displaying the spatial distribution
  of the overall accuracy per grid cell (i.e. percent agreement).
• Fixed a bug with the RasterStreamsToVector tool that resulted in overlapping
  traced streams.
• The D8FlowAccumulation tool has been modifed to use a fixed flow-width to
  calculate specific contributing area, equal to the average grid cell resolution.
  The tool previously used a variable flow-width for SCA calculations, however,
  1. this differs from the constant value used in Whitebox GAT, and 2. a
     variable flow-width means that flow accumulation values do not increase
     continuously in a downstream direction. This last issue was causing problems
     with applications involving stream network extraction. This change does not
     affect the 'cells' nor 'catchment area' outputs of the tool.
• Fixed a bug with the GeoTIFF NoData tag.
• Fixed a bug with the SetNodataValue tool.

WhiteboxTools - WhiteboxTools v0.12.1

Version 0.12.0 (22-11-2018)
Tools Added

• The following tools were added to the project:
  BlockMaximumGridding
  BlockMinimumGridding
  Clip
  Dissolve
  Erase
  JoinTables
  Intersect
  LasToShapefile
  LidarClassifySubset
  LinearityIndex
  LineIntersections
  LongestFlowpath
  MergeTableWithCsv
  MergeVectors
  NearestNeighbourGridding
  PatchOrientation
  Polygonize
  RasterToVectorLines
  SplitWithLines
  SymmetricalDifference
  Union
  VoronoiDiagram

Other Changes

• Modified the algorithm used by the CostDistance tool from an iterative method of
  finding the minimum cost surface to one that uses a priority-flood approach. This
  is far more efficient. Also, there was a bug in the original code that was the
  result of a mis-match between the neighbouring cell distances and the back-link
  direction. In some cases this resulted in an infinite loop, which is now resolved.
• Improvements have been made to the WhiteboxTools GeoTIFF reader. A bug has been
  fixed that prevented tile-oriented (in contrast to the more common strip-oriented)
  TIFF files from being read properly. Support has been added for reading rasters
  that have been compressed using the DEFLATE algorithm. Lastly, the WhiteboxTools
  GeoTIFF reader now supports sparse rasters, as implemented by GDAL's GeoTIFF driver.
• An issue in the SAGA raster format reader has been fixed.

WhiteboxTools - WhiteboxTools v0.11.0

This release is marked by the addition of several vector data processing capabilities. Most notably, this includes support for TINing and TIN based gridding (vector and LiDAR), as well as several vector patch shape indicies. The following tools were added to the project:

• AddPointCoordinatesToTable
• CentroidVector
• CompactnessRatio
• ConstructVectorTIN
• ElongationRatio
• ExtendVectorLines
• HoleProportion
• LayerFootprint
• LidarConstructVectorTIN
• LidarTINGridding
• LinesToPolygons
• Medoid
• MinimumBoundingCircle
• MinimumBoundingEnvelope
• MultiPartToSinglePart
• PerimeterAreaRatio
• PolygonArea
• PolygonPerimeter
• RasterStreamsToVector
• RasterToVectorPoints
• RelatedCircumscribingCircle
• RemovePolygonHoles
• ShapeComplexityIndex
• SinglePartToMultiPart
• SmoothVectors
• SumOverlay
• TINGridding

Other Changes

• Added a minimum number of neighbours criteria in the neighbourhood search of the
  LidarGroundPointFilter tool. In this way, if the fixed-radius search yields fewer
  neighbours than this minimum neighbours threshold, a second kNN search is carried
  out to identify the k nearest neighbours. This can be preferable for cases where
  the point density varies significantly in the data set, e.g. in the case of
  terrestrial LiDAR point clouds.
• The MinimumBoundingBox tool has been modified to take an optional minimization
  criteria, including minimum box area, length, width, or perimeter.
• Fixed: Bug that resulted in a 0.5 m offset in the positioning of interpolated grids.
• Fixed: Viewshed tool now emits an intelligible error when the viewing station does
  not overlap with the DEM.
