Source Code for Importing and Processing SRTM DEM Data

This MATLAB library provides comprehensive source code for importing and processing SRTM (Shuttle Radar Topography Mission) Digital Elevation Model data. The implementation specifically supports SRTM-3 format files with 3-arcsecond (~90 meter) resolution, while excluding support for higher-resolution SRTM-1 files (1-arcsecond, ~30 meter). The codebase includes essential functions for DEM data handling, featuring automated file parsing routines that extract elevation matrices from standard .hgt binary formats. Key functionality encompasses digital elevation data visualization through customized plotting functions that generate topographic maps with elevation color coding. Analytical capabilities include terrain analysis algorithms for slope calculation, aspect derivation, and hydrological feature extraction using flow accumulation methods. For elevation analysis, the library implements statistical functions for terrain profiling, elevation distribution analysis, and cross-sectional terrain examination. These computational tools enable researchers to perform sophisticated geospatial analysis, supporting applications in geological studies, geographical research, environmental modeling, and terrain-dependent scientific investigations through standardized MATLAB programming interfaces.
