Quick Review of FABDEM for Hydrological Applications with QGIS
Channel: Hans van der Kwast
Date: 2022-02-08

In this video we compare the new FABDEM (Forest And Buildings removed Copernicus DEM) with SRTM for stream and catchment delineation in QGIS.

FABDEM Data: Laurence Hawker, Jeffrey Neal (2021), FABDEM. https://doi.org/10.5523/bris.25wfy0f9ukoge2gs7a5mqpq2j7
Journal article FABDEM: https://iopscience.iop.org/article/10.1088/1748-9326/ac4d4f

The analysis has been done with the PCRaster Tools plugin: https://jvdkwast.github.io/qgis-processing-pcraster/
