In rsi: Efficiently Retrieve and Process Satellite Imagery

rsi 0.3.1

• A test that requires online resources is now skipped on CRAN. There are no user-facing changes in this version.

rsi 0.3.0

• rsi has been peer-reviewed by the rOpenSci project! Huge thank you to @OldLipe and @mdsumner for their extremely helpful reviews.

• sentinel2_mask_function() now masks out SCL values of 2, "DARK_AREA", by default.

• landsat_mask_function() gains an argument, masked_bits, that allows you to specify the values you wish to mask out by bit values rather than just integers. Refer to the Landsat science product guide for further information on what bit values represent for your platform of interest.

• get_stac_data() no longer fails if downloading an asset fails, but instead returns a raster with all available data. This may still fail when a single asset fails to download while downloading multiple assets combined within a single raster; please open an issue if this happens to you! Thanks to @laurenkwick in #74 (#75).

rsi 0.2.1

• calculate_indices() gains several new arguments:
• overwrite, which is passed directly to terra::predict(). Thanks to @Cidree in #69 (#70).
• wopt and cores, which are passed directly to terra::predict().

• extra_objects, which lets you provide additional objects for calculating indices inside of the minimal environment used to isolate potentially untrustworthy code.

• Band mapping objects now have a c() method, making it easier to add assets you wish to download to an existing object. Thanks to @laurenkwick in #71 (#72).

• stack_rasters() gains a new argument, check_crs, which can be set to FALSE to skip checking if all rasters share the same CRS.

• Added a new section to the "How can I?" article on the pkgdown site, with pointers on how to "Calculate all possible indices using a certain data set". Thanks to @alkimj in #60 (#61).

rsi 0.2.0

Deprecations

• default_query_function() has been renamed to rsi_query_api(). Please update any code using the old name; it will be removed in a future release.

New features

• get_stac_data() gains an argument, download_function, which takes a STACItemCollection object and returns a data frame, where columns correspond to distinct assets, rows correspond to distinct items, and cells contain file paths to the downloaded data.

• rsi_download_rasters() is a new function that exposes how get_stac_data() downloads assets.

• get_alos_palsar_imagery() and alos_palsar_mask_function() are new functions to help you get and mask ALOS PALSAR imagery, respectively. Thanks to @h-a-graham via #48 and #50.

• get_naip_data() is a function for getting National Agricultural Imagery Program data from (by default) Planetary Computer. Data covers the continental United States.

• landsat_mask_function() gains an argument, include, which lets you specify whether you'd like to include pixels that represent land ("land"), water ("water"), or both ("both"). Thanks to @mateuszrydzik for the report via #37 (#46).

Bug fixes and other changes

• Progress bars have been split into separate bars for downloading, masking, compositing and so on.

• get_stac_data() no longer errors in (rare) circumstances where calculating the intersection of bounding boxes between your AOI and an individual item, performed when setting composite_function = NULL, produces a bounding box with ymin or xmin higher than ymax or xmax.

• Functions will no longer error if you construct their arguments with glue::glue() (or otherwise if they have more than one class).

• stack_rasters() will only rename bands if band_names is the same length as the number of bands in the output raster (or missing, or defined by a function). It will now warn you if these lengths are different. Previously, if you provided more than the required number of band names, stack_rasters() would silently ignore the extra names, and would error if you provided fewer names than bands.

• get_stac_data() now warns if asset_names is NULL and there is more than one asset per item.

• Functions sending HTTP requests now set a user agent of rsi (https://permian-global-research.github.io/rsi/)

rsi 0.1.2

• get_stac_data() no longer includes mask_band in its outputs when composite_function = NULL. Add this band to asset_names to include it in the download.

rsi 0.1.1

• get_stac_data() now removes colons (:) from the file names generated when composite_function = NULL. This means that datetimes are now generally formatted as YYYY-MM-DDTHHMMSSZ, which is slightly dissatisfying but is a valid path on Windows systems (thanks to @jguelat, #29, #32).

• stacK_rasters() no longer includes "-r", "bilinear" in its default value for gdalwarp_options (#27, #30).

• get_stac_data() now provides a more informative error when 0 items are found for a given query (#26, #31).

rsi 0.1.0

• Initial CRAN submission.
