After draining the northern flank of the Alps Mountains in Germany and Austria, the Danube River flows east as it enters this west-looking scene (upper right) and forms the border between Slovakia and Hungary. The river then leaves the border as it enters Hungary and transects the Transdanubian Mountains, which trend southwest to northeast. Upon exiting the mountains, the river turns southward, flowing past Budapest (purplish blue area) and along the western margin of the Great Hungarian Plain. South and west of the Danube, the Transdanubian Mountains have at most only about about 1300 feet of relief but they exhibit varied landforms, which include volcanic, tectonic, fluvial, and eolian features. Image was generated from a Landsat satellite image draped over an elevation model produced by the Shuttle Radar Topography Mission (SRTM). Color contrasts between the major land cover types, namely vegetation (green), bare ground (red), and water (blue). Elevation data acquired by the SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000.
