Get DEMs and orthoimagery from the USGS National Map, georeference your images and merge rasters, and visualize with Unity 3D
get_tiles now displays a bulleted list of endpoints (again?), rather
than a jumble of raw markdownadd_bbox_buffer properly sets the CRS of the output when attempting to
buffer geodesic coordinates.combine_overlays
importFrom tag to terrainr-package.R to silence R CMD CHECK NOTE.vector_to_overlay deals with missing CRS in
vector_data:
error_crs, behaves just like error_crs in
add_bbox: if NULL, the function will give a warning when assuming
CRS; if FALSE, the function will assume a CRS silently, and if
TRUE, the function will error if vector_data is missing a CRS.target_crs has been removed. vector_data will be given the CRS of
reference_raster if it doesn't have its own CRS, and will always be
projected to the CRS of reference_raster.error_crs has been added to mirror add_bbox_buffer: if NULL and
your input data has no CRS, vector_to_overlay will warn about
assuming the raster CRS. Set to TRUE to error or FALSE to ignore
the warning.transparent = "false" to
minimize the number of times the backup method to merge_rasters (see
below) is called. To restore the old behavior, set transparent = "true"
in either get_tiles or hit_national_map_api.get_tiles will now infer bboxSR and imageSR from provided sf or
Raster objects if not otherwise specified. To restore the old behavior,
set bboxSR and imageSR to 4326 in get_tiles (or set your data's
CRS to 4326 before calling get_tiles).merge_rasters can once again handle merging mixed-band rasters (such as
NAIP images with and without alpha bands). At the moment this is using the
older, slower implementation and will raise a warning. (#30, #32).ggplot2 from vector_to_overlay now that
ggplot2 is requiredcalc_haversine_distance (not exported) now assumes it's been provided
with degrees. coord_units has been removed as an argument.get_tiles.terrainr_bounding_box has been removed; it should no longer be
possible for users to have terrainr_bounding_box objects unless they
were using non-exported functionality.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).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.calc_haversine_distance
point_from_distance
rad_to_deg
deg_to_rad
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.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.calc_haversine_distance has been internally simplified somewhat to
reduce code duplication.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 appropriatelyget_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.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.transportation endpoint has moved servers, and is now handled by the
same function that handles DEMs and orthoimagesterrainr is now main
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.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
imageget_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 appropriatelyget_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.output_image argument to merge_rasters now has a default value of
tempfile(fileext = ".tif") to be a little more friendly to users.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.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.
