I have been trying to use the new Bision plug-in to work with GeoTiffs and Meshes.
I downloaded a GeoTiff from OpenTopography and inputted into “Import Mesh DEM” component to generate a mesh from it. But the elevation is clearly exaggerated, I do not understand why… I scaled the mesh in Z just to make it look better, but I would like to have the real elevation as close as possible.
I tend to think it has to do with the plug-in itself, as the GeoTiff is a standard one from OpenTopo…
I also have doubts regarding the dimensions of the mesh, as the inputs seem to be in pixels…
I am not sure what values to input so that the mesh has the real extension in kilometers…
Sample: Sampling factor as nth pixel to read
XDimension: X dimension pixel size.
YDimension: Y dimension pixe size.
Hope someone can shed some light on these issues for me.
Unfortunately Tiff isn’t a supported/authorized extension, so I cant upload it, but if you need more info like the metadata of the GeoTiff I can provide it.
