Geomorph: Open-Source Terrain Analysis & Modeling
An open-source browser-based software for spatial analysis and modeling of terrain, allowing users to visualize, analyze, and model elevation data sets.
What is Geomorph?
Geomorph is an open-source, browser-based software tool for spatial analysis and modeling of digital elevation models (DEMs). It enables users to load in DEM data sets, visualize them in 2D and 3D, and perform a variety of terrain analysis techniques to quantify land surface processes and landform patterns.
Some key features and capabilities of Geomorph include:
- Interactive 3D visualization of landscape topography
- Contour mapping and hillshading raster layers
- Specialized terrain indices for landform characterization (e.g. Topographic Position Index)
- Spatial analysis tools for hydrology and geomorphology
- Manual and automated landform classification
- Scriptable workflow with Python programming interface
- Export analysis results, maps, 3D scenes
- Cross-platform web app requiring only a browser
Geomorph is well-suited for researchers, students, or professionals working with high-resolution topographic data. It facilitates both visualization for conceptual interpretation as well as quantitative land surface analysis. The open architecture encourages custom scripting and analysis methods as well. Geomorph represents a user-friendly, flexible option for topographic data analysis.
