More tests are flagged to skip on CRAN, or when run offline
georeference_overlay should give fewer useless
warnings
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).geom_spatial_rgb() about “dropped
aesthetics”.govunits test.ggplot2 now requires a minimum of 3.4.0merge_rasters no longer warns that options aren’t
respected when using the fallback method before immediately passing said
options to gdalwarp.rlang with string
interpolation via glue.rlang and glue have been added to
Importsraster now requires a minimum version of 3.5-19.make_unity is a new function which uses the new
unifir package to automatically create Unity scenes, no
clicking necessary.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.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.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).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).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.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
fastergdalUtils has been removed from dependencies following
CRAN directionsrgdal is now an explicit dependency (had previously
been imported via gdalUtils)ecosystems, has been added to
get_tiles and hit_national_map_api.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.sf now has a minimum dependency of 1.0-5, to take
advantage of an upstream bug fix (relating to merge_rasters
overwrite)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.raster_to_raw_tiles is now deprecated and will be
removed in a future release (no earlier than 2022). Use
make_manifest instead.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.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).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.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.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.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.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_overlaysimportFrom 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_distancepoint_from_distancerad_to_degdeg_to_radgeom_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
mainmerge_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_bboxraster_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.These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
