WhiteboxTools v1.0.2

• Added the BurnStreamsAtRoads tool.
• Added a two-sample K-S test (TwoSampleKsTest) for comparing the distributions of two rasters.
• 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.

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 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 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 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).

WhiteboxTools v0.14.1

This is a bug-fix release with only one major feature addition, the RasterArea tool.

WhiteboxTools v0.14

• This release largely focusses on bug-fixes rather than adding new features. However, the
  following tools for measuring surface roughness in a DEM were added to the project:
  CircularVarianceOfAspect
  EdgeDensity
  SurfaceAreaRatio
• Fixed a bug that resulted in rasters with projected coordinate systems being
  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 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 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 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

• Medoid
• MinimumBoundingCircle
• MinimumBoundingEnvelope
• MultiPartToSinglePart
• PerimeterAreaRatio

• 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.
