Problems displaying mosaicked raster three dimensionally in ArcScene

[KeithProsk]

I'm trying to display a mosaicked DEM made in ArcMap in ArcScene three dimensionally. To do this i'm trying to float the mosaicked DEM on its own surface in the base heights>floating on a custom surface option. All I get is a column of black shooting up through where the DEM used to be in ArcScene. I've tried several raster resolutions (in the base heights menu) and still get the same thing.

I mosaicked the raster using the 'mosaic to new raster' tool, and the mosaicked DEM does contain ocean (0 values). Also, would chosen pixel type chosen when mosaicking affect this?

Any suggestions would be greatly appreciated, and please be detailed in any descriptions since I'm relatively new to Arc.

Greetings,

It sounds like your data's coordinate system is in geographic coordinates.  Try projecting the data to a projected coordinate system that uses feet/meters.  Ideally, your x, y, and z unit should all be the same.  If you don't want to project the data you can visualize it in ArcScene by going to the Main Menu > View > Scene Properties.  In the vertical exaggeration box type a small number like 0.0003, or try hitting the Calculate From Extent button.

Regards,
Eric

Thanks Eric,

the projection still had the same problem, but changing the vertical exaggeration worked perfectly.
