I'm using ArcGIS 10.0 and trying to open a digital elevation model in ArcScene. I'm working on a project and got the DEM data from official sources which is quite huge. The resolution of the DEM is 1 meter. The total size is unknown but I think it's about 10km in diameter. The total file size is 1.5 GB.

Trying to add the DEM to ArcScene, using rightclick on Scene layers > Add Data and selecting the DEM, gives me the following message:

Could not add the specified data object to the scene. Try using a smaller subset.

Failed to open raster dataset.

Is the DEM too big? Why is that message? Could it be my total memory is not enough?

I'm running ArcScene 10.0 in a VirtualBox machine with Windows 7x86, with 2 processors 3.2 GHz and 4 GB memory allocated.

How to select a smaller subset? I neither see any option to do so nor find any subsets.

I solved this issue finally. The problem was I was accessing the DEM on a mounted UNIX-type data partition which was formatted ext4.

Copying the whole DEM to a Windows-type partition (NTFS formatted) allowed me to open the DEM in both ArcMAP and ArcSCENE.
