Clean any spatial data layer (shape file)

Many shape files contain errors, places where the edges of a polygon cross over or polygons which overlap. This helps remove some of those errors by smoothing the edges of polygons, removing corners, and dissolving edges where polygons overlap. This reduces the complexity of the shape file, making future steps faster.

Usage

clean(spatial_data, ...)

Arguments

spatial_data: spatial data frame from sf.
...: extra options (currently not used)

Value

An sf object with simplified and validated geometry.
