Nine ARC/INFO coverages of historical features of the Northern Tracts of the KSR were prepared based on mid-nineteenth century Government Land Office surveys. Coverages were created from photocopies of the original Government Land Office plat maps (approximate scale 1:32,000) obtained from the Kansas State Historical Society (Topeka, KS). For the plat maps covering KSR Northern Tracts, exterior township boundaries were surveyed in 1855-1856, and the interior section lines were surveyed in 1860. These coverages are valuable for examining the early character of KSR lands. Original field notes accompany the plat maps and should be consulted for additional information on biotic and cultural features. Users of these data should become familiar with the quality, characteristics and limitations of these early Government Land Office surveys (as is well described in the scientific literature). For example, vegetation is generally mapped as either forest or prairie occurring as a sharp boundary; more likely savanna and open woods occurred in transition areas. Another problem is that map elements generally become less accurate as distance from section lines increases; this is because the original plat maps were largely created by cartographers using surveyed distances of elements along sections lines, with only a description or sketch of the location of elements on the interior of the section.

Varner, KSR GIS technician, prepared materials for digitizing, digitized maps, and completed all other technical aspects for the project during 1991, with logistical support from W. Dean Kettle. During 1997, coverages were retrieved and processed by Pinde Fu, KSR GIS technician, in the GEMLab of Dr. Paul Rich at the University of Kansas. Export files (.e00) were retrieved and processed into coverage and shapefiles by Jorgina A Ross at the Kansas Biological Survey, May 2006. |
