Keep original geometries of sf objects
Description
When intersections occur, what was originally 2 polygons features can become
LINESTRING and/or POINT and any COLLECTIONS or MULTI- versions of these.
This function evaluates what the original geometry was and drops any newly created
different geometries. For example, if a POLYGON becomes a COLLECTION of
MULTIPOLYGON, POLYGON and POINT geometries, the POINT geometries will
be dropped. This function is used internally in postProcessTo().
Usage
keepOrigGeom(newObj, origObj)
Arguments
newObj |
The new, derived |
origObj |
The previous, object whose geometries should be used. |
Value
The original newObj, but with only the type of geometry that entered
into the function.
