DATA SUMMARY

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 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 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.
