Welcome to demcompare’s documentation!

Demcompare is a python software that aims at comparing two DEMs together.

A DEM is a 3D computer graphics representation of elevation data to represent terrain. demcompare has several characteristics:

  • Provides a wide variety of standard metrics and allows one to classify the statistics.

  • Works whether or not the two DEMs share common format projection system, planimetric resolution, and altimetric unit.

  • Performs the coregistration based on the Nuth & Kääb universal coregistration method.

  • Classifies the stats by slope ranges by default, but one can provide any other data to classify the stats.

A comparison report can be compiled as html or pdf documentation with statistics printed as tables and plots.
