I'm trying to model the great lakes bathymetric data for a cnc. I'm using Qgis to handle the conversion
The Geotiff was obtained from https://www.ngdc.noaa.gov/mgg/greatlakes/erie.html
using the raster calculator I removed the elevation above 0 ("erie@1" <= 0)*"erie@1"
I've tried using DEMto3d plugin to generate the stl file, but I can't get it to look like the raster in qgis
I have tried increasing the exaggeration factor in the plugin (demto3d) to 10 and even used the raster calculator to exaggerate the the raster file before converting. "erie@1"*100
