About this document

Terrain Feature Extraction Algorithms by roscao2001 is a document available to read on EtoBox.

This document surveys algorithms for extracting significant terrain features from two terrain models: regular square grids (RSGs) and triangulated irregular networks (TINs). Section 2 introduces these two models as well as contour line models. Section 3 describes algorithms for extracting features from RSGs, including early work by Peuker and Douglas from 1975 using elevation differences between points and neighbors to identify peaks, pits, passes, and other features. Section 4 discusses approaches for extr
