Comprehensive Terrain Analysis#

Complete geomorphological analysis of a DEM: morphometry, hydrology, terrain indices, classifications, and statistics. Produces a ZIP package with rasters, vectors, CSVs, and a JSON manifest.

Inputs:

  • DEM Package (ZIP). ZIP file from Search & download Planetary Computer containing a DEM GeoTIFF and manifest.json

  • Contour Interval (m). Elevation interval for contour lines in meters (default: 10)

  • Major Contour Interval (m). Elevation interval for major contour lines in meters (default: 50)

  • Watershed Threshold (cells). Minimum number of cells for watershed delineation (default: 500)

  • TPI Small Radius (cells). Neighborhood radius for small-scale TPI in cells (default: 5)

  • TPI Large Radius (cells). Neighborhood radius for large-scale TPI in cells (default: 25)

Outputs:

  • Terrain Analysis Package (ZIP). ZIP archive with rasters, vectors, statistics, and manifest

  • Summary. Human-readable summary of the terrain analysis results

  • Manifest JSON. JSON manifest string describing all outputs
