  • 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.
