The mission covered the Earth between 60?N and 57?S and will provide interferometric digital elevation models (DEMs) of approximately 80% of the Earth's land mass when processing is complete. The radar-pointing angle was approximately 55? at scene center. Ascending and descending orbital passes generated multiple interferometric data scenes for nearly all areas. Up to eight passes of data were merged to form the final processed Shuttle Radar Topography Mission (SRTM) DEMs. The effect of merging scenes averages elevation values recorded in coincident scenes and reduces, but does not completely eliminate, the amount of area with layover and terrain shadow effects". 517 3 $aVoid filled SRTM digital elevation model of Afghanistan 517 3 $aVoid filled Shuttle Radar Topography Mission digital elevation model of Afghanistan 607 $aAfghanistan$vRelief models 700 $aChirico$b Pete$01389288 701 $aBarrios$b Boris$01393435 712 02$aUnited States.$bAgency for International Development. 712 02$aGeological Survey (U.S.) 801 0$bGPO 801 1$bGPO 906 $aBOOK 912 $a9910696364103321 996 $aVoid-filled SRTM digital elevation model of Afghanistan$93449579 997 $aUNINA
