See the r-spatial blog for details of this evolution. We will fully remove support for Spatial classes (from package sp) in the next release in Summer 2023.

It will be removed completely in Summer 2023.bec and tsa layers are now downloaded directly from the BC Data Catalogue.

(#92, #93)tools::R_user_dir("bcmaps", "cache") to determine the cache directory, while when R version is < 4.0, it will use rappdirs::user_cache_dir("bcmaps"). This is to align with CRAN’s storage policy using the tools approach while maintaining backwards compatibility with older R versions. Unfortunately this will require users who updated to version 1.0 to re-download layers because we are caching layers in a different location on your file system from that version. Users wishing to clear the old cache location could run bcmaps::delete_cache() before updating to bcmaps 1.0.1.

All data has been removed from the bcmaps package and moved to the bcmaps.rdata package, which is hosted on the bcgov drat repository: https://github.com/bcgov/drat. That package must be installed in order for bcmaps to access the data. It can be installed with: install.packages('bcmaps.rdata', repos='https://bcgov.github.io/drat/')
In previous versions of bcmaps, data was stored in the package and loaded by calling data("layername") or simply layername (e.g., data("bc_bound") or bc_bound).
Now loading data requires a function call - either using a shortcut function that is the same name as the dataset (e.g., bc_bound() whereas previously one would simply use bc_bound). Alternatively, one can use the get_layer() function (e.g., get_layer("bc_bound")).
Another major change is that all the layers are now returned as sf classes by default, rather than Spatial classes. Spatial versions of the data can still be obtained by setting the class argument to "sp" in get_layer() and the shortcut functions (E.g., bc_bound(class = "sp") or get_layer("bc_bound", class = "sp")).

self_union performs a union on a single SpatialPolygons* object to take into account overlaps. Polygon attributes are combined in a nested dataframe.get_poly_attribute allows you to easily parse a nested data frame column (created by self_union) to extract or calculate the attributes you wantAdded a couple of convenience functions:
transform_bc_albers() transforms a Spatial object to BC Albers projectionfix_self_intersect() checks for and repairs self-intersecting polygonsAdded 3 Natural Resource layers (areas, regions and districts)
Added high resolution BC boundaries (bc_bound_hres)
Added bc_area function
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.
