It looks alright to me. The moving average algorithm searches (for each pixel) for points within the specified radius, and then averages the values of all those points.
"gdal_grid" also supports inverse distance or linear interpolation if you want a more smooth result. It is perhaps surprising that QGIS only exposes a small subset of gdal_grid's capabilities. -- Sent from: http://osgeo-org.1560.x6.nabble.com/GDAL-Dev-f3742093.html _______________________________________________ gdal-dev mailing list firstname.lastname@example.org https://lists.osgeo.org/mailman/listinfo/gdal-dev
