The Ames Stereo Pipeline (ASP) was initially developed for Mars Global Surveyor satellite and built on technology for the Mars rovers.Ī team at NASA Ames Research Center extended the toolkit to handle earth-orbiting satellites and they continue to support the open source project.ĪSP uses an area-based image matching algorithm that searches for matching points on the two source images by comparing pixel patterns using a moving window within a search space constrained by the sensor collection geometry.

Refer to the SETSM homepage for more information and source code.īoth ArcticDEM and REMA are processed using SETSM Publications SETSM also iteratively refines the platform sensor model, reducing the bias introduced by satellite model uncertainty.

This object-space matching approach allows SETSM to produce output at the full image resolution if desired. Unlike other elevation extraction algorithms, SETSM employs a vertical line locus search strategy, which inverts the normal method by varying the assumed elevation of a given point, instead of the horizontal coordinate values, to find the best match.

Each iteration of the algorithm uses the results of the previous level to refine and limit the image search space. It uses a hierarchical image matching strategy that begins by matching one image to the other at a coarse resolution. The Surface Extraction with TIN-based Search Space Minimization (SETSM) algorithm was written by Myoung-Jong Noh and Ian Howat at The Ohio State University.

More information is below on each of the software packages and algorithm details. The PGC primarily uses two open-source software packages for creating stereo-derived elevation models, SETSM and ASP.
