Problems with SDR sample data (Gura) and my data

Great! I’m speculating a bit, but making sure that the nodata value is defined in the input rasters might make it a whole lot easier to see the patterns in the results.

Hi @CTXBrabbs , thanks for updating the data. The results are not actually all 0, but a default rendering in GIS might make it look that way because there are some extremely high/low values in the output rasters that skew the distribution and make it difficult to apply a colormap that shows the variation in the values. One reason for this might be the fact that the input rasters do not have a nodata value defined. For example, if I look at the DEM, all the black areas around the outside should…
