DESCRIPTION

r.intersect creates a vector line at the intersection point of two raster maps. For example if a planar trend surface or dynamic flooding level raster map is available this module can create a "bathtub ring" vector line at the intersection of that map and a coincident elevation map.

NOTES

This module uses r.contour internally, which can use a lot of memory in very large regions.
