Resources

Our policy is to promote resources which are free and, to the best of our knowledge, reliable. So we emphasize, but do not necessarily rely exclusively, on open source software and data available freely on the internet.

Tools

• The WaterBase tools

• MapWindow is our current choice of GIS tool.

• SWAT (Soil and Water Assessment Tool) is the hydrological modeling tool we are currently using.

• FreeGIS is a major source of information on free resources for GIS: tools, geo-data, documentation, and projects

Data

The main data inputs for hydrological modelling are digital elevation, land use, and soil. These are the sources our data is currently based on:

• SRTM 90m Digital Elevation Data

• USGS Global Land Cover Characterization (GLCC) database

• FAO/UNESCO Soil Map of the World and Derived Soil Properties.
