Land Cover Continuity Analysis

Summary

Continuity analysis of land cover from stream network.

The algorithm performs a shortest path exploration from stream pixels, and records the maximum land cover class on the path to every pixel.

The assumption is that the numeric counts for land cover classes reflect an ordering of those classes along a given gradient, typically an artificialization gradient (from the most natural/undisturbed to the most artificialized/disturbed).

The resulting map represents the continuity of land cover along the gradient of the land cover classes.
