Data analysis and download on WaPOR portal

Start using WaPOR portal at https://wapor.apps.fao.org/

In this video, you will learn:

  • How to start using the WaPOR portal
  • How to select and display data layers on the portal

Data analysis tools on WaPOR portal

In this video, you will learn how to use the WaPOR portal analysis tool. This tool can be used to:

  • Extract time-series data of a point 
  • Extract time-series data of an area
  • Calculate crop water productivity rasters of an area from total biomass water productivity.


Note: When you are saving points or areas into MyWaPOR, they are only saved for that level. For example, points and areas saved in Level 1 (Continental 250m) can only be used for analyses in Level 1 and are not available for use in Levels 2 (National 100m) or Level 3 (Sub-national 30m). This is due to the different geospatial reference systems used for each level.

The uploaded shapefile must have the same spatial reference system of WaPOR dataset (EPSG:4326 for Level 1 and 2).

Common Errors: When using WaPOR 'Area Time Series', if you have the same error as below, try to save the area to MyWaPOR without space in the name. For example, 'myplot' instead of 'my plot'. 

Download raster data from WaPOR portal

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.


Note: Downloaded raster data need to be corrected with a conversion factor. You can do this in GIS software (ArcGIS, QGIS, etc.). In the next unit, there will be more tutorials on processing raster data in QGIS.
