2. Data Output Formats

Select Data Output Format:

3. Layer Types & Additional SRTM Data

Digital Elevation Models (DEMs)

Digital Terrain Model (DTM)
Digital Surface Model (DSM)

Include Global 30m SRTM Data

5. Canopy Height Model (CHM)

Generate Canopy Height Model from DSM and DTM

This algorithm requires both Digital Terrain Model (DTM) and Digital Surface Model (DSM) from step 3 above. To enable DTM and DSM click here

6. Contour Lines

    Generate contour lines
    Output smoothed DEM
    Generate visualization

This algorithm requires either Digital Terrain Model (DTM) or Digital Surface Model (DSM) from step 3 above. To enable DTM/DSM click here
