Input Data

Raster Component

Input data consist of whichever variables are needed for the CLEWs model in RASTER format. Their extent may be global or custom, country or region specific.

The global raster inputs so far have been acquired from public sources such as NASA and other research institutes, consisting of satellite acquired data as well as research based models. Current inventory of global raster inputs are as follows:

• Landcover
• Rainflux
• Water Table Depth

In addition, some inputs in consideration are:

• CarbonFlux (Net Ecosystem Excchange)
• Solar Horizontal Irradiation
• Wind Power Density Potential
• Global Livestock Distribution

The raw input data from your sources may consist of a variety of raster formats (netCDF, HDF, TIFF etc). However this CLEWs process is designed for simpler raster formats, therefore all inputs were converted to TIFF.

Vector Shapefile Component

This project uses administrative boundaries shapefiles that are used to clip the raster components to specific countries.

The Global Administrative Unit Layers GAUL is implemented by FAO.
