n2khab 0.10.1 (2023-12-04)

• Silently ignore errors from package {remotes} during package loading (56e9c06).

n2khab 0.10.0 (2023-12-01)

Breaking change

read_GRTSmh(), read_GRTSmh_base4frac(), read_GRTSmh_diffres() and read_raster_runif() now return a SpatRaster object from {terra} by default (#173). Previous behaviour using {raster} can still be restored; see below. However do note that {raster} is a legacy package and {terra} is its successor.

New feature

The package can be configured using options() or corresponding environment variables. Current configuration state is returned by n2khab_options(). See ?n2khab_options for information on package configuration.

Two settings are now available:

• optionally use {raster} instead of {terra} (#173);
• optionally set a custom n2khab_data path, affecting all functions that need this path (#174).

Deprecated functions

read_schemes() and read_scheme_types() were moved to a new package {n2khabmon}. In {n2khab} they are still functional but deprecated, and will eventually disappear (#175). The accompanying data sources schemes and scheme_types have moved to {n2khabmon}. {n2khab} 0.10.0 will be the minimum version required by {n2khabmon}.

n2khab 0.9.1 (2023-11-24)

• Added workaround for a note during package installation (d300e4a).
• Package startup message: improve recommended code to update package (793e303).

n2khab 0.9.0 (2023-11-22)

• download_zenodo() has been improved (#169):
  • fixes in order to use the renewed Zenodo website;
  • speedup the initiation of a multi-file download;
  • set concurrent (parallel) downloading as default for multi-file records;
  • add unit tests to regularly check that the function still works.
• read_watersurfaces() gained extra capabilities (#168):
  • data source version watersurfaces_v1.2 is now supported;
  • a new fix_geom argument allows to fix invalid or corrupt geometries on the fly. This behaviour is turned off by default (see #60).
• Package startup messages have been updated, including a check whether the latest release is being used (#170, 502c3a2).
• Internally, an update has been applied (9691ec2) to googlesheets authentication, used in updating the built-in textual data sources. These data sources have not changed since previous release.

n2khab 0.8.0 (2022-11-18)

• Reference list namelist has been updated with improved type names (#163; thanks @jeroenvdborre).
• Paper by De Saeger et al. (2017) is now referred in documentation of read_habitatmap() and derived functions (#165).
• Git repository: branch master is replaced by main (#164).

n2khab 0.7.0 (2022-05-23)

• Upgrade most vc-formatted data sources to the format of {git2rdata} version 0.4.0. In this version, files not optimized for version control (but rather for readability), are saved as csv instead of tsv files. For {n2khab}, this applies to the types and env_pressures data sources. Since it is expected that this upgrade is not compatible with older {git2rdata} versions, the version dependency for {git2rdata} has been updated (#161).
• scheme_types data source: update typegroup membership of type 7210 in scheme GW_03.3 (#161).

n2khab 0.6.0 (2022-02-03)

New features

• Function read_shallowgroundwater() to return the shallowgroundwater data source (#156).
  • The raw data source shallowgroundwater represents the areas in the Flemish region of Belgium where the mean lowest groundwater level is estimated to be less than approximately 2 m below soil surface (inbo/n2khab-preprocessing/pull/61; https://doi.org/10.5281/zenodo.5902880).
• Reference lists types, schemes, scheme_types, namelist were updated (#150, #151, #154, #158):
  • a few type name updates (thanks S. De Saeger);
  • updated value of groundw_dep for type 91F0;
  • environmental pressures ep_07.2 and ep_07.4 received updated (Dutch) explanations;
  • scheme HQ2190 has been replaced by two schemes HQ2190_terr and HQ2190_aq;
  • typegroups were defined for scheme GW_05.1_aq (with contributions from L. Denys & A. Leyssen).
• Readme (homepage): a new installation method using inbo.r-universe.dev has been added and is recommended (#153, 746fb81).

n2khab 0.5.0 (2021-05-12)

Support for new data source versions

The following new data source versions are now supported by their associated reading functions:

• habitatmap_2020 (read_habitatmap() - #139)
• habitatmap_stdized_2020_v1 (read_habitatmap_stdized() - #139, #140)

• habitatstreams_v1.7 (read_habitatstreams() - #114)
• watersurfaces_v1.1 (read_watersurfaces() - #118)
• watersurfaces_hab_v4 (read_watersurfaces_hab() - #142)

Function documentation was updated accordingly and refined.

New functions

• Function read_raster_runif() to return the raster_runif data source (#136, #138)
  • The raw data source raster_runif is a raster with cells matching those of GRTSmaster_habitats. Their values are uniformly distributed random numbers between 0 and 1 (inbo/n2khab-preprocessing/pull/55 and following pull requests; https://doi.org/10.5281/zenodo.4745983).
• Function checksum() and associated shortcut functions to calculate file checksums (#122)

Other updates & internal changes

Including:

• scheme_types data source: updates in typegroup memberships of MNE scheme GW_05.1_terr (#116)
• expand_types() now also supports expanding 5130_hei to 5130 (#143)

n2khab 0.4.0 (2021-02-10)

New feature

• Function read_watercourse_100mseg() (#105) to return the watercourse_100mseg data source or one of its elements. watercourse_100mseg is a new processed data source (inbo/n2khab-preprocessing/pull/44; https://doi.org/10.5281/zenodo.4452577).

Updates & internal changes

Including:

• Update namelist data source: Dutch shortname of one type changed (#102).

  • note on handling proj4string warnings;
  • improved explanation of git workflows in developing the package.
• Continuous integration: leave Travis CI; add new GitHub Actions workflows (#108).
• Website: larger fontsize; Ubuntu Mono font for code; consistent colouring of hyperlinks (#110).

n2khab 0.3.1 (2020-10-26)

Minor patch

• read_watersurfaces() has been limited explicitly to using data source version 'watersurfaces_v1.0'. Accommodation of the newer 'watersurfaces_v1.1' is planned for later.

n2khab 0.3.0 (2020-10-16)

Breaking change

• Functions that preprocess (non-included) N2KHAB data sources have been simplified by dropping their path argument (#92). Existing R code will continue to run normally if you complied with the recommended file organization (see vignette("v020_datastorage") and vignette("v022_example")) and did not set the path and file arguments.

New features

• New function read_habitatquarries() for reading the habitatquarries data source (#83, #94, inbo/n2khab-preprocessing/pull/41).
• Updates in reference lists (#88, #93, 7ce3b32):
  • schemes & scheme_types: updates of spatial restrictions, names and typegroup names of MNE schemes (for defining the schemes' target populations);
  • types: update groundwater dependency of type 2170.

Internal changes

  • types: updates of flood dependency scores and hydrological class of several types, following several expert discussions and checks
  • schemes & scheme_types: updates regarding spatial restrictions, types and typegroup memberships of MNE schemes (for defining the schemes' target populations); added MHQ scheme 'HQ2120'
  • env_pressures: updated explanations. Each pressure now has its own explanation
  • namelist: according updates
• renv framework implemented to enhance reproducibility of generating the built-in textual data sources (#72)
• read_env_pressures(): an extra column 'remarks' is now returned (#65)
• New function read_soilmap() for reading the soilmap or processed soilmap_simple data sources (#29; inbo/n2khab-preprocessing/pull/34)

Historical note

This package is the successor of the {n2khabutils} package. Previous to commit c8608d9, the code was part of the n2khab-monitoring repo (formerly 'n2khab-inputs'), where the original version history remains stored. At that time, the package was called {n2khabutils}. As a convenience, the {n2khab} repo still holds the rewritten (shrinked) package history from before commit c8608d9, as defined by the related files and folders. See this issue in the 'n2khab-monitoring' repo, where the migration is documented.
