Global Data

The following data may be used to help build your SWAT models.

Weather Data

Additional Data

Please note: we advise only using the landuse and soil maps below when nothing better is available.

Landuse Maps

The landuse maps below come in the form of zip files containing 1 or more tiles for each continent. They come in two resolutions, the originals at approximately 400 meters (at the equator) and the resampled at 800 meters. The first are a little more accurate but the they take some time to load and minipulate. You may prefer to use the resampled ones at least while you are learning or experimenting.

Landuse data was constructed from the USGS Global Land Cover Characterization (GLCC) database.

Soil Maps

The soil maps below come in the form of zip files containing 1 or more tiles for each continent.

Also available are some notes and a readme file from the FAO, the source of the soil data.

World Data Grids

This is a QGIS project contained in a zip archive that allows you to graphically select the DEMs, landuse, and soil maps that you need for your location. Just unzip the archive and open the project file World_Data_Grids.qgs in QGIS.

Lookup Tables

The lookup tables (global_landuses and global_soils) are supplied with QSWAT+ in the project database, as is the soil database (global_usersoil). The landuses are all defined in the standard SWAT+ plant database, also supplied with QSWAT+
