A new R package for working with path and row numbers from the World Reference System (WRS) grids (both WRS-1 and WRS-2) is now available on CRAN.
wrspathrow includes functions for determining the path and row number(s) needed
to cover a given spatial object, or, conversely, for returning the polygon for
a given path and row. Note that installation of the
wrspathrow package may take
a bit of time due to the need to download the
it depends on. The
wrspathrowData package is approximately 26MB in
size, as it includes the full WRS-1 and WRS-2 vector grids in R format. My
thanks to the USGS for allowing the re-release of these reformatted datafiles
on CRAN. See the USGS WRS-1 and WRS-2 shapefile download
page for the original
source of these files.
