Sink (depression) removing in a DTM using QGIS and validation
Channel: Geoinformatics
Date: 2020-04-14

In this video, I demonstrate some different approaches to removing sinks (depressions) from Digital Elevation models and how to validate the result creating blue spot maps and using the profile plugin.
This video is the second of a series of four where I look at modeling urban surface water flow in QGIS
