GDALRaster-class

  • add methods for color tables: getColorTable(), getPaletteInterp(), setColorTable()
  • add getRasterColorInterp(), setRasterColorInterp(): get/set color interpretation for raster bands
  • add getDescription(), setDescription(): get/set description for raster band objects
  • add flushCache(): flush all write cached data to disk
  • add getFileList(): returns a list of files forming the dataset
  • add infoAsJSON(): returns output of the gdalinfo command-line utility as a JSON-formatted string
  • new(): add a warning in the class constructor if the raster has an int64 data type (would be handled as double for now)

GDAL API stand-alone functions

  • add bandCopyWholeRaster(): wrapper for GDALRasterBandCopyWholeRaster(), efficiently copy a whole raster band
  • add createColorRamp(): wrapper for GDALCreateColorRamp(), automatically create a ramp from one color to another
  • add sieveFilter(): wrapper for GDALSieveFilter() in the Algorithms API, remove small raster polygons
  • add PROJ utility functions: proj_version(), proj_search_paths(), proj_networking() (via GDAL headers)
  • add g_buffer(): compute buffer of a WKT geometry (GEOS convenience function via GDAL headers)

CmbTable-class

  • add updateFromMatrixByRow(): update the hash table from a matrix having integer combinations arranged in rows
  • add asMatrix(): return the combinations table as a numeric matrix (alternative to asDataFrame())

Bug fix

  • warp() caused segfault if proj.db could not be found (#96)

Other miscellaneous

  • plot_raster(): default value of the legend argument has been changed to FALSE; legend can now use a color table for continuous data; add argument maxColorValue (e.g., to use RGB 0:255 instead of 0:1 in col_tbl)
  • bbox_from_wkt(), bbox_to_wkt(): add arguments extend_x, extend_y
  • on Windows, reset GDAL environment variables on package unload if they were previously set on load
  • add inst/extdata/storml_tcc.tif: example dataset of NLCD Tree Canopy Cover
  • update the package vignette for color tables and raster display
