| This map was produced from several larger digital              datasets. Topography was derived from Shuttle Radar Topography Mission              (SRTM) 85-meter digital data. Gaps in the original dataset were filled              with data digitized from contours on 1:200,000-scale Soviet General              Staff Sheets (1978–1997). Contours were generated by cubic convolution              averaged over four pixels using TNTmips1 surface-modeling              capabilities. Minor artifacts resulting from the auto-contouring              technique are present. Streams were auto-generated from the SRTM              data in TNTmips as flow paths. Flow paths were limited in number              by their Horton value on a quadrangle-by-quadrangle basis. Peak elevations              were averaged over an area measuring 85 m by 85 m (represented by              one pixel), and they are slightly lower than the highest corresponding              point on the ground. Cultural data were extracted from files downloaded              from the Afghanistan                Information Management Service (AIMS) Web site              (http://www.aims.org.af). The AIMS files were originally derived              from maps produced by the Afghanistan Geodesy and Cartography Head              Office (AGCHO). Because cultural features were not derived from the              SRTM base, they do not match it precisely. Province boundaries are              not exactly located.

This map is part of a series that includes a geologic map, a topographic                  map, a Landsat natural-color-image map, and a Landsat false-color-image                  map for the USGS/AGS (Afghan Geological Survey) quadrangles covering                  Afghanistan. The maps for any given quadrangle have the same open-file                  report (OFR) number but a different letter suffix, namely, -A, -B, -C, and -D                  for the geologic, topographic, Landsat natural-color, and Landsat                  false-color maps, respectively. The OFR numbers                  range in sequence from 1092 to 1123. The present                  map series is to be followed by a second series, in which the geology                  is reinterpreted on the basis of analysis of remote-sensing data,                  limited fieldwork, and library research. The second series is to                  be produced by the USGS in cooperation with the AGS and AGCHO.
