I'm using a DEM of Mars I got from UA's HiRISE website, and I want to convert it into an STL for 3D printing using the DEMto3D plugin.

However, the raster values are all negative, so I thought I could convert them into positive values using the Raster Calculator. Any time I try this though, I get an error message saying that "Raster calculator : Could not create destination file."

I haven't had this problem before working with HiRISE DEMs on QGIS, so I uninstalled and reinstalled the program, but that didn't work.

This is the link from which I got the DEM: https://www.uahirise.org/dtm/dtm.php?ID=ESP_027802_1685

  • Turns out that the DEMto3D plugin worked fine even with the negative values, guess I don't need to use raster calculator at all.

Previously, the plug in didn't seem to accept negative elevation values, so I tried to use the Raster Calculator as per this answer about Mars DEMs, but more recently it turns out that the plugin will work just fine with negative elevation values.
