This brief tutorial introduces Zonal Statistics with an example of aggregating human population data from a WorldPop raster file to a GADM adminstrative boundary polygon file. This video uses Q-GIS 3.2.3 (Bonn).
This work was sponsored by the US Defense Threat Reduction Agency's Cooperative Biological Engagement Program/Biological Threat Reduction Program in Southeast Asia.
