WebThe original polygons are intersected and divided so that each overlap area becomes a single, separate polygon. If necessary, the user can merge subdivided polygons into a single polygon of the same type. The Intersect Polygons command can be used to create new polygons from the common overlapping areas between the intersecting polygons. … WebAug 29, 2024 · go.geo (deprecated) Go.geo is a geometry/geography library in Go. The primary use case is GIS geometry manipulation on the server side vs. in the browser using javascript. This may be motivated by memory, computation time or data privacy constraints.
