I import a 3DES IMG raster layer formatted in NAD83 metric vertical units (EPSG:26911) from the USGS 3D Elevation program. When I look at the elevation values in the layer properties, they appear to be about 1/3.2808 of the expected elevations. The layer comes in with a range of 254 to 304 meters in an area that ranges from 2732 to 3261 feet in the real world. That should translate to a range of 832-994 meters. This roughly corresponds to it converting from feet to meters, but the source is in meters already.
Is there a way to verify the source IMG values?
Is there a way to prevent this conversion (assuming the source data is valid) in QGIS?
