One of a series of three X-SAR/SRTM images (E-2774 though E-2776), this radar amplitude image and the other images show the basin of Kathmandu, the capital of Nepal. The series includes a detail (E-02775, with dimensions of 27 kilometers x 30 kilometers) of the X-SAR digital elevation model (shown in JSC2000-E-02776). This radar amplitude image is a measure of the backscattering of the transmitted microwaves. In the amplitude image the Bagmati River is visible south of the city center and the international airport in the eastern part. The runway appears as a dark stripe. The airport is well known for its difficult landing/takeoff conditions due to the close vicinity of the surrounding high mountains. The scene is located at 85 degrees, 15 minutes east longitude and 27 degrees 45 minutes north latitude. Note: All X-SAR imagery and related charts and maps are provided by DLR, Germany's national aerospace resource center as well as the national space agency.
