GEO TIFF File

[Brian_Washburn]

It looks like you are trying to import a Hillshade, which is meant for visualization purposes and does not contain elevation information. See a similar issue here:

GEOTIF import Problem in Bison

Along the lines of what @wim said, it looks like the tif you are trying to import is the hillshaded version of dgm_1m_3918-04_2015.tif, which is meant for visualization and not for creating terrain (all the data gets stripped out to make the tif more visually readable). Heron would not be able to create terrain from a hillshade either. Did you try the file without *_shd_* in the file name? -Brian

I was able to download a tiff file from swissALTIRegio which imported just fine with Heron (and probably would work in Bison as well). I then tapped into the ch.swisstopo.images-swissimage layer of the wms.geo.admin.ch WMS GetMap service to get an aerial image to map on the topo.
