I'm trying to export an elevation layer acquired through Get Map Data, but CE produces a file that's not in the same location as the original. There are no options to pick in the export dialog, so I guess this is a bug?
What are you trying to export as? What is the coordinate system of the scene you are trying to import it in? What is the position and extent of the data you downloaded?
I managed to fix the problem by assigning the original terrain image's spatial reference through Catalog.
I used File > Export > Selected Terrain as Image, geoTiff. The scene is in EPSG 31467. Extent varies, 1x1km and upward.
