Meta-data on active GRASS locations

GRASS uses "locations"to store sets of rasters and vectors with the same coordinate reference system (CRS). These rasters and vectors may or may not be in the same actual location on Earth–they just have the same CRS. This function returns information on all of the GRASS "locations" that have been initialized. It is mainly useful for developers.

NB: fasterRaster always uses the "PERMANENT" mapset.

Usage

.locations(warn = TRUE)

Arguments

warn

Logical: If TRUE (default), display a warning if no GRASS "locations" have been created.

Value

A named list. The names are the "location's" names and the values are the coordinate reference strings.
