OSMscale
is an R package to easily handle and project
lat-long coordinates, download background maps and add a correct scale
bar to ‘OpenStreetMap’ plots in any map projection. There are some other
spatially related miscellaneous functions as well.
OSMscale
is available on CRAN:
It relies on OpenStreetMap to do the
actual work, thus rjava
must be available, see installation
tips.
