Problems adding elevation data

DanSocaciu — Sat, 01 Jun 2019 06:47:35 GMT

Hi everyone, I am just starting to use ArcGIS Pro, and I am trying to create a local scene.

I exported a DEM model from Agisoft Photoscan as a a GeoTiff Elevation Data. I also exported a high quality JPEG that I want to drape over the elevation data. The problem is that when I add the .tif as a elevation source it says "an elevation surface needs to contain supported elevation information and the data source needs to be accessible". The .tif displays fine as a raster, showing a black and white contrast image.

I assume it has something to do with how I export the DEM from Photoscan. I do not understand what the no-data value is, I tried it as -3.40282, I found that value on a different forum regarding ArcMap.

Any help would be appreciated, I am trying to figure things out as I go. Thank you

-3.402823466e+38 I suspect, Was it a 32 bit tiff? The export format and type will give a clue to the nodata value

It is a 32 bit tiff. I tried that no data value, but now it doesn't work even as a raster image. Metsa2.tif is the one with -3.40282 value and that displays properly as a raster. Nothing works as an elevation source.

Solved now, I just had to run the raster to tin tool, and use the tin file as an elevation source.

My ArcGIS Pro (v3.3.1) was telling me the same ("An elevation surface needs to contain supported elevation information and the data source needs to be accessible") when I tried to add a DEM raster as an elevation source in a Local Scene. It appeared OK as a 2D layer in the scene though.

I fixed it by defining spatial reference with the "Define Projection" GP tool.
