2.0.0 (05-19-2020)

  • Adding Python 3.8 support and dropping Python 3.6 support.

  • Adding GDAL 3 support and dropping GDAL 2 support. The only non-backwards
    compatible issue in GDAL 2 to GDAL 3 is the need to handle Axis Ordering with
    osr.SetAxisMappingStrategy(osr.OAMS_TRADITIONAL_GIS_ORDER) because of
    https://trac.osgeo.org/gdal/wiki/rfc73_proj6_wkt2_srsbarn#Axisorderissues?.
    Since Axis ordering now matters for Geographic CRS the expected order is
    Lat,Lon but we use osr.OAMS_TRADITIONAL_GIS_ORDER to swap to Lon,Lat.

  • Using osr.CreateCoordinateTransformation() instead of
    osr.CoordinateTransformation() as the GDAL 3 call.

  • Fixed a bug in convolve_2d that would not ignore_nodata if the signal
    raster's nodata value was undefined. Changed the name of this flag to
    ignore_nodata_and_edges to reflect its expected functionality.

  • Warped signed byte rasters are now also signed byte rasters.

  • Adding a GitHub Actions-based build job for building wheels and a source
    distribution for a given commit of pygeoprocessing.

  • Updated setup.py to point the URL project link to the project's new
    home on GitHub.

  • Updated MANIFEST.in to only include files that should be there in the
    pygeoprocessing source distribution. This fixes an issue where files
    matching a variety of extensions anywhere in the pygeoprocessing directory
    might be included with the source distribution.

  • Added set_tol_to_zero to convolve_2d to allow for in-function masking
    of near-zero results to be set to 0.0.

  • Fixed malformed logging outputs which could be seen during long running
    rasterize calls.

  • Renamed all parameters involving Spatial Projections to the form
    [var_id]_projection_wkt, this involves optional arguments in
    reproject_vector, warp_raster, transform_bounding_box,
    and align_and_resize_raster_stack as well as the return value from
    get_raster_info and get_vector_info.

  • Fixed an issue in zonal_statistics that would crash if an aggregate
    vector had a feature with no geometry defined. Now the function ignores
    such features and prints a warning to the log.

  • Fixed a malformed ValueError message when a corrupt raster was
    encountered in raster_calculator.

  • Fixes an unnecessary calculation that pre-fills slope raster GeoTIFFs with
    nodata values.

  • Added a check to convolve_2d to verify that raster path/band tuples were
    passed where expected and raise a useful Exception if not.

  • Removed most of the pygeoprocessing.testing module and added the following
    convenience functions to pygeoprocessing, which should not be used
    for production code but are useful for testing and scripting:

    • raster_to_numpy_array - read a single band of a raster into a numpy
      array, runs the risk of memory error if the raster is too large.
    • numpy_array_to_raster - writes a numpy array to a raster on disk.
    • shapely_geometry_to_vector - creates a vector from a list of
      Shapely geometry.

  • Fixed an issue in flow_dir_mfd that would cause invalid flow directions
    on DEMs that had very small numerical delta heights.

  • Fixes an issue in convolve_2d that would occasionally cause undefined
    numerical noise in regions where the signal was nodata but mask_nodata
    was set to False.
