%description
Calculates distances from point locations to features. The usual approach
for eg. resource selection function analyses is to generate a complete
distance to features surface then sample it with your observed and random
points. Since these raster based approaches can be pretty costly with
large areas, and often lead to memory issues in R, the distanceto package
opts to compute these distances using efficient, vector based approaches.
As a helper, there's a decidedly low-res raster based approach for
visually inspecting your region's distance surface. But the workhorse is
distance_to.
