This means that get_resources() has to be run in every new R session to make resource available for further processing (#219).Rasters are now cropped to the spatial extent of an asset with setting snap="out", thus delivering a slightly bigger extent (#212).
Speed improvements for GFW indicators (up to x10 for larger rasters) now require R package exactextractr to be installed. Also, it is advised to have the R package landscapemetrics installed to gain the full computation speed improvement.
calc_indicators() checks for 0-length tibbles (#196, #199, #215)..read_raster_source() now uses a simplified logic to cover all cases (e.g. single tiles, tiled rasters with and without temporal dimension, single temporal rasters) (#211).snap="out" by default (#212)..read_raster_source() now projects assets in case their CRS differs from the portfolio (#213).sf objects instead of being written to disk (#219)..read_raster_source() now applies a precision round-trip of 5 decimal point to match rasters with slight changes in their spatial extent (#217).register_resource() and register_indicator() now issue warnings for resources/indicators with names already registered and overwrites them (#220).added new resource called ucdp_ged providing a database of violent conflict from 1989 to today
added a new indicator called fatalities aggregating number of deaths by type of conflict on a monthly time scale based on the ucdp_ged resource.
Added a new resource called fritz_et_al providing a raster layer of deforestation
added a new resource called fritz_et_al providing a raster layer of deforestation drivers in tropical forests based on Fritz et al. (2022)
added a new indicator called deforestation_drivers using the fritz_et_al resource to obtain information on the absolute and relative area driving forest losses in assets for the period 2008-2019
added two new exported functions register_resource() and register_indicator() which allow users to register custom functions for resources/indicators
added a new vignette for the web-version of the package only informing about how to obtain wide-output from indicators
added a new vignette for the web-version for a custom analysis of the NASA FIRMS resource in the example section
added the data for years 2017-2020 to the Global Mangrove Watch resource
Changed the parallel backend to the future package. Parallel processing is now implemented by furrr::future_map() on the asset level within the calc_indicators() function. User code is now required to set up a plan() to enable parallel processing. The function call needs to be wrapped on the user side with progressr::with_progress() to show a progress bar.
mapme.biodiversity no longer sets terra’s temporal directory for you. Instead you have to call terra::terraOptions() manually
esalandcover indicator now returns the value per each land cover class exactly once (#177)disabled running examples on CRAN
disabled tests for get_* functions on CRAN
terra engines now use get() to resolve the requested zonal statistic function
applying tidyverse coding style to existing code (#156, @karpfen)
extensive re-factoring of vector-raster zonal statistic engines (#150)
extensive re-writing of testing infrastructure for indicator functions omitting the usage of snapshot tests as far as possible (#142)
rundir and todisk arguments removed from indicator functions since they were of no practical use
instead of a resource and indicator backlog, resources and indicators are now registered to .pkgenv and queried there during runtime. This also allows users to register custom resources/indicator functions
removed deprecation warnings for old resource/indicator name
on MacOS s2-based calculations are now enabled so users can expect the package to return numerically equivalent results on any operating system (#131)
the online source for the nasa_srtm resource shows an expired SSL certificate since November 2022. The get_resources() function now includes an error and instructions how to disable SSL certification at a users own risk. The websites maintainers have been contacted and asked to renew the certification. (#131)
GFW resources are now updated to use the latest version allowing analysis for the additional year of 2021 (#123, @fBedecarrats)
GFW indicators now accept numeric min_size argument allowing to specify fractional covers (#110)
fire indicators now allow the simultaneous calculation of indicators based on MODIS and VIIRS. Before users had to chose between one of the instruments for each analysis (#126)
case when one or multiple assets return NA instead of a tibble is now properly tested and handled (#101)
Rasters are no longer temporary written to disk to omit a bug caused by applying mask/classify to an already existing raster file (#108, @Jo-Schie)
Bug with soilproperties set to NA caused by the function to return a data.frame instead of a tibble was fixed (#116)
both, treecoverloss_emissions and treecover_area_and_emissions now return 0 instead of NaN for observation years where now forest loss occurred (#120)
.make_global_grid() now specifies the CRS when constructing the bounding box and returns the grid in the specified CRS instead of Lat/Lon (#113)
.calc_active_fire_properties now uses st_coordinates to retrieve locations of fires (#119, @DavisVaughan)
tests for MacOS have been re-enabled (#131)
tests for downloading nasa_srtm resource are skipped because the SSL certificate of the online source has expired (#131)
extensive renaming of resources and indicators. These are handled gracefully until the next release (i.e. a warning is issued and names are replaced):

init_portfolio() now sets the testing attribute to FALSE by default.get_<resource>() functions now return filenames early if testing is set to TRUE.calc_<indicator>() examples now copy files to the R temporal directory and are wrapped in try() to avoid errors/warnings on CRAN if an internet resource is not available.calc_tri() and calc_elevation() are now disabled on CRAN because of the responsiveness of CIGAR servers.NEWS.md file to track changes to the package.init_portfolio() is used to initialize a portfolio object. The input must be an sf object where all geometries are of type POLYGONget_resources()calc_indicators()write_portfolio()read_portfolio(). If users wish to download additional resources or calculate indicators, init_portfolio() has to be called again.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.
