# difference-polygons
Given a "land" shapefile, remove all the shapes from one or more other shapefiles, producing a new shapefile that only has the "difference".
## Usage
difference-polygons -l ./land_polygons.shp -r ./dont_want.shp -r water_polygon.shp -o not_covered.shp
### Min area filter
Use the `-a`/`--min-area` option to drop any resultant shapes that are less than this size (e.g. `-a 1e-09`). Area is based on units of the shapefiles's coordinate reference system.
