Hi, I have been using DHS GPS points in the past, and used buffers around the points when extracting values from geospatial covariates (2km if urban cluster, 5km buffer if rural cluster). Now I have come across this paper https://spatialdata.dhsprogram.com/references/DHS_Covariates _Extract_Data_Description_3.pdftime calculator and I was wondering if the overall guidelines on extraction are moving away from the buffers method to extracting to the actual point (although displaced)? Many thanks!
