How to use WaPOR portal

4. Downloading WaPOR raster data

In this video, you will learn how to download raster data from the WaPOR portal. With WaPOR portal, you can collect raster data for the whole layer or a small area using 'Area Raster Download' in the analysis tool.

Downloaded raster data need to be corrected with a conversion factor so that pixel values in the raster show physical unit of the variable. You can do this using the' Raster calculator' tool in GIS software (ArcGIS, QGIS, etc.). The next page will provide a tutorial on how to pre-process raster data in QGIS.
