Use this tag when asking questions related to where features overlap.

GIS features can intersect in many ways. For examples see:

The concept of "intersection" may include more than just sharing common points (the set-theoretic model): when considering the topology of the features, intersections can be further refined according to which parts of the features overlap (interior, boundary, and exterior) and how they overlap (such as a transverse intersection of polylines compared to tangential contact).

In addition, intersection is a place or area where two or more objects (e.g. streets) intersect as well as the set of elements common to two or more sets; especially the set of points common to two geometric configurations
