terrainr 0.2.0

  • Breaking changes:
    • merge_rasters loses the argument merge_raster. For the "georeference
      a single image" use case, see the new georeference_overlay function.
    • get_tiles gains an argument resolution (details below) between
      side_length and services. No functionality should be changed, but code
      with unnamed arguments to services, verbose, or georeference may be
      impacted.
  • New features:
    • A new family of functions for dealing with overlay creation:
      • vector_to_overlay lets users quickly produce image overlays from
        vector data.
      • georeference_overlay replaces the use of merge_raster for creating
        single-file georeferenced overlay files.
      • combine_overlays lets users, well, combine overlays into a single
        image
    • get_tiles gains an argument, resolution, specifying the number of
      meters each pixel should represent (so higher images result in smaller
      downloads).
    • get_bbox provides an S3 generic to create terrainr_bounding_box
      objects. In this version, that means users can use get_bbox to get
      bounding boxes from sf and RasterLayer objects, and it means adding
      methods will be easier going forward. The generic get_bbox method
      is equivalent to get_coord_bbox
    • raster_to_raw_tiles handles rectangles appropriately
  • Improvements and bug fixes:
    • get_tiles, raster_to_raw_tiles, and merge_rasters are now much more
      conscientious about deleting tempfiles when they're done with them.
    • merge_rasters no longer fails when handed a mix of 3- and 4-band raster
      files. The current implementation will cast all 4 band rasters to 3 band
      images and then return a 3 band raster image.
    • The output_image argument to merge_rasters now has a default value of
      tempfile(fileext = ".tif") to be a little more friendly to users.
    • Arguments lat and lng to get_bbox (and get_coord_bbox) no longer
      need to be quoted -- either the tidyverse-feeling NSE approach or the
      more standard quoted argument approach will work.
  • Internal changes:
    • All terrainr-provided functions now explicitly use the terrainr::
      namespace.
  • Changes in dependencies:
    • sf has been added as an explicit import due to vector_to_overlay. sf
      is required by gdalUtilities, also imported by this package, so this
      change should have no impact on users.
    • rlang is added as a dependency to allow lat and lng be unquoted in
      get_bbox.
    • ggplot2 has been added to Suggests due to vector_to_overlay.
    • jpeg and tiff have been added to Suggests due to
      georeference_overlay. I'd expect more image libraries to join this list
      over time.
