• More tests are flagged to skip on CRAN, or when run offline

• georeference_overlay should give fewer useless warnings

• New query method is dramatically faster and less-error prone.

• Updated contours URL to new location
• Removing dependencies on raster and rgdal
• Fixed infinite loop when following two-stage APIs
• Removed HRO, as the endpoint appears to have disappeared

• New features:
  • Two new endpoints are available: HRO, which provides orthoimagery for non-CONUS US domains, and USGSNAIPImagery, which only returns NAIP (whereas USGSNAIPPlus, the default for ortho, will use HRO where appropriate).
• Improvements and bug fixes:
  • Updated NAIP URL to its new home, which should reenable NAIP downloads.
  • Fixed warning in geom_spatial_rgb() about "dropped aesthetics".
  • Fixed govunits test.
• Dependency changes:
  • ggplot2 now requires a minimum of 3.4.0

• Improvements and bug fixes:
  • Redocumented package to stay on CRAN.
  • merge_rasters no longer warns that options aren't respected when using the fallback method before immediately passing said options to gdalwarp.
  • Starting to move error messages into rlang with string interpolation via glue.
• Dependency changes:
  • rlang and glue have been added to Imports
  • raster now requires a minimum version of 3.5-19.

terrainr 0.7.0

• New features:
  • make_unity is a new function which uses the new unifir package to automatically create Unity scenes, no clicking necessary.
  • Internally, all calls to functions from {raster} have been replaced with calls to {terra}. This future-proofs the package against any coming deprecations and takes advantage of newer, faster terra code. This is not intended to be a breaking change; any methods that previously took {raster} objects should still work (and silently convert to {terra} under the hood). If you have any workflows impacted by this change, please file a bug report!
• Improvements and bug fixes:
  • make_manifest, transform_elevation, and transform_overlay no longer error when providing non-standard side lengths; they now warn as intended.
  • make_manifest, transform_elevation, and transform_overlay should no longer give warnings about nodata values in most cases. being clamped to 0.
  • Fixed some documentation, unused objects, restyled and removed lints.
  • transform_overlay (and by extension, every Unity overlay importer) now tries to automatically guess the scale of the input raster. Values under 1 are scaled from 0-1, integers under 255 are scaled 0-255, and integers under 65535 are scaled 0-65536. The main effect of this is more realistic coloring when importing terrain. Floats above 1 won't be affected.
• Dependency changes:
  • terra is now included as an Import (had been recursively imported through raster previously).
  • raster and rgdal are now in Suggests (used temporarily in Raster* methods for get_tiles and add_bbox_buffer, until the new version of raster hits CRAN).
• Internal changes:
  • raster_to_raw_tiles is now a thin wrapper around the functions transform_overlay and transform_elevation. It is no longer tested; it will be removed entirely in the next release (see deprecation notice in terrainr 0.5.0).

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)

terrainr 0.5.1

• New features:
  • A new endpoint, ecosystems, has been added to get_tiles and hit_national_map_api.
• Improvements and bug fixes:
  • merge_rasters gains an argument, overwrite, which allows you to specify whether or not to overwrite output_raster if it exists. Previous versions expected you to pass "-overwrite" to options. If a file exists at output_raster and overwrite is FALSE, merge_rasters will throw an error.
• Dependency changes:
  • sf now has a minimum dependency of 1.0-5, to take advantage of an upstream bug fix (relating to merge_rasters overwrite)

(This time for real -- this release matches the one published to CRAN)

• New features:
  • A new function, make_manifest, now helps automate the import of terrain and imagery to Unity. It fully replaces raster_to_raw_tiles (see Deprecations below). Documentation updates are forthcoming.
• Deprecations:
  • raster_to_raw_tiles is now deprecated and will be removed in a future release (no earlier than 2022). Use make_manifest instead.
  • The method get_tiles.list is now deprecated and will be removed in a future release (unexported in Fall 2021, removed no earlier than 2022). Convert your list to an sf object instead.
  • The bbox argument to hit_national_map_api is now documented as "An object from [sf::st_bbox]." This is a change from the earlier options of a length 2 list or terrainr_bounding_box object. Those methods are currently still supported, but undocumented; they will be removed in a future release (no earlier than 2022).
• Improvements and bug fixes:
  • get_tiles no longer mangles data with projected coordinates (via a fix to the internal function split_bbox). If for some reason you want the old behavior back, set the new argument projected to FALSE while providing projected data.
  • The documentation for add_bbox_buffer and set_bbox_side_length now specifies that they should only be used with geographic coordinate systems. If you use these functions with projected data, they will warn; this may be upgraded to an error in future versions.
  • The README images are now of beautiful Hyampom, California, a somewhat more appealing vista than the original Mt Marcy scene.
  • The "Import to Unity" vignette has been rewritten to use make_manifest, as has the overview vignette and other documentation.
  • Typos in the message merge_rasters gives when using the fallback method have been fixed.
  • merge_rasters gains an argument force_fallback which, if TRUE, will use the older, slower method for merging tiles. This is not recommended, but is useful for testing.
• Internal changes:
  • The slow removal of all terrainr_* custom classes marches on! These classes should no longer be present in any user-facing, non-deprecated code; the only functions still relying on custom classes are internal utilities and the split_bbox function responsible for tiling get_tiles requests.
  • split_bbox should now run faster, particularly for large tile sets, as some nested loops have been vectorized.
  • Improvements to test coverage and CI.
