mapme.biodiversity (development version)

mapme.biodiversity 0.4.0

CRAN release: 2023-08-28

New features

  • 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

Breaking changes

  • 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

Bug Fixes

  • esalandcover indicator now returns the value per each land cover class exactly once (#177)

Internal

  • 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

mapme.biodiversity 0.3.0

CRAN release: 2023-01-21

Breaking changes

  • 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)

New features

  • 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)

Bug fixes

  • 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)

Internal

  • .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)

mapme.biodiversity 0.2.1

CRAN release: 2022-09-09

Bug fixes

  • fixes a serious bug that occurred for tiled resources when multiple assets are within the same tile resulting in returning the same tile multiple times

Internal

  • tests to catch above mentioned bug have been introduced for tiled resources

mapme.biodiversity 0.2.0

CRAN release: 2022-08-23

Breaking changes

  • extensive renaming of resources and indicators. These are handled gracefully until the next release (i.e. a warning is issued and names are replaced):

  • resources:

  • treecover2000 -> gfw_treecover

  • lossyear -> gfw_lossyear

  • greenhouse -> gfw_emissions

  • traveltime -> nelson_et_al

  • nasagrace -> nasa_grace

  • mintemperature -> worldclim_min_temperature

  • maxtemperature -> worldclim_max_temperature

  • precipitation -> worldclim_precipitation

  • ecoregions -> teow

  • mangrove -> gmw

  • srtmdem -> nasa_srtm

  • indicators:

  • treecover -> treecover_area

  • emissions -> treecoverloss_emissions

  • treeloss -> treecover_area_and_emissions

  • chirpsprec -> precipitation_chirps

  • accessibility -> traveltime

  • popcount -> population_count

  • checks for tile availability reactivated for SRTM
  • fixed notes due to uninitialized variables in TEOW and biome indicators

mapme.biodiversity 0.1.1

CRAN release: 2022-05-02

Internal

  • 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.
  • examples for calc_tri() and calc_elevation() are now disabled on CRAN because of the responsiveness of CIGAR servers.
