I've downloaded a bunch of the NED 10 meter data and trying to create a mosaic dataset. The dataset gets created easily enough, but once the rasters are added, the values get messed up. Elevation is in meters from NED. Once entered into the mosaic dataset the values all become exponential 3.4022e+038. I must be missing something as it appears (random guess) that my meters are being perhaps converted to DD. Thoughts?
