terrainr v 0.3.0

terrainr 0.3.0

• Breaking changes:
  • terrainr_* classes have been effectively removed and are no longer
    exported. Functions which previously expected these objects now generally
    accept sf and Raster class objects instead. Functions which previously
    returned these objects now generally return sf objects instead (#24).
  • The list returned by get_tiles now uses the service names provided by
    the user, not the endpoint names. This means that
    get_tiles(..., services = "elevation") will now use the name elevation
    instead of 3DEPElevation, and remain standard across versions (#12).
  • get_bbox and get_coordinate_bbox have been removed. Functions that
    used to expect terrainr_bounding_box objects now accept objects of class
    sf or raster (#24).
  • add_bbox_buffer loses the divisible argument. For precise control over
    side length, use set_bbox_side_length (which should be more accurate, if
    slightly more conservative, than the divisible system ever was) (#17).
  • convert_distance has been removed (internally replaced by the
    units package) (#7).
  • merge_rasters loses the input_images and output_image function, as
    most downloaded files are now already georeferenced. To recreate this
    functionality, georeference image tiles directly via
    output <- georeference_overlay(img_tiles, ref_tiles, tempfile(fileext = ".tif"))
    and then provide output to merge_rasters.
  • A handful of utility functions are no longer exported:
    • calc_haversine_distance
    • point_from_distance
    • rad_to_deg
    • deg_to_rad
• New features:
  • Two new functions, geom_spatial_rgb and stat_spatial_rgb, allow you to
    use RGB map tiles as backgrounds for further plotting.
  • calc_haversine_distance gains an argument coord_units allowing it to
    handle coordinates in radians as well as degrees.
• Improvements and bug fixes:
  • georeference_overlay provides tempfile(fileext = ".tif") as a default
    output location if no output_file is provided.
  • get_tiles now tells you what tiles it's retrieving, not retriving.
• Internal changes:
  • calc_haversine_distance has been internally simplified somewhat to
    reduce code duplication.
  • All services arguments to hit_national_map_api and get_tiles can
    now handle both base64 and binary returns, removing the need to manually
    categorize endpoints (54ad9fb).
    • hit_national_map_api auto-detects whether API endpoints are
      returning base64 or binary and handles them appropriately
    • get_tiles now auto-detects whether hit_national_map_api is
      returning base64 or binary and writes to file appropriately.
  • hit_national_map_api is now more likely to fail with a human-friendly
    error message if API endpoints return a non-200 status (54ad9fb).
  • hit_national_map_api (and by extension get_tiles) now register a user
    agent.
  • Changes in dependencies:
    • gdalUtilities has been removed, with functionality replaced by sf.
    • rlang has been removed, with functionality removed.
    • units has been added.
    • ggplot2 has been moved to Imports (was previously in Suggests) due to
      the new geom_spatial_rgb and stat_spatial_rgb functions.
