terrainr v 0.6.0

terrainr 0.6.0

• New features:
  • Two new functions, transform_elevation and transform_overlay, should
    now provide raster transformation functions that were possible with
    raster_to_raw_tiles but not with make_manifest. As an added bonus, the
    internal code to handle tiling is now dramatically simpler.
• Improvements and bug fixes:
  • make_manifest will now overwrite any file at importer_path, in line
    with documented behavior. Previous versions would never overwrite
    importer_path.
  • merge_rasters' fallback method now runs much faster
• Dependency changes:
  • gdalUtils has been removed from dependencies following CRAN directions
  • rgdal is now an explicit dependency (had previously been imported via
    gdalUtils)
