get.spatial.overlap: get.spatial.overlap
In kmcd39/xwalks: Helper function for calculating geographic correspondence (crosswalks) and a set of bundled xwalks for selected areas
Description
Calculates the
unique/row identifier column for each; returns a row for each combination of
rows in the input sfs that intersect with one another with a column for the
percent overlap.
artifact of differing resolutions between the shapefiles or other artifacts
of their representation. Filtering to geometries below a very small
using filter.threshold or otherwise can remove these slivers.

filter.threshold
percent overlap between sf1 and sf2, as decimal,
below which to trim results before returning.
