Drainage Basin Geomorphometry
data, with 15 arc sec drainage basins and stream networks.
- Data sets by continent, with very large shapefiles.
- Created by ESRI products, so you might be able to adapt to other data
sets (so far I have no interest in that).
- I have excluded drainage basins less than 100 km²,
by filtering the basin shapefiles and exporting the larger basins.
This makes operations run much faster, and I don't trust the statistics for
the small basins, mostly along the coast.
Start on Analyze,
Batch processing, Drainage basin menu option.
- Make basin DEMs
- Compute Thalwegs
- Caculate basin statistics (threaded)
- Merge DBF files
