Hi Cat, you'll need to Download a DEM coverter tool to convert the Elevation maps to a readable form ( .tif, .bmp, .jpg) and so on, you can get one here: http://www.okino.com/conv/imp_dem.htm or if your'e on a mac here:http://www.treeswallow.com/macdem hope this helps:-)

Do atleast one thing a day that scares the hell outta ya!!
