Data integration of Soil Survey Geographic Database data with layers of The National Map and data from archived geologic maps.

This research integrates soil data from the Soil Survey Geographic Database (SSURGO) of the U.S. Department of Agriculture with layers from The National Map of the U.S. Geological Survey and bedrock geology data from archived geologic maps from the Missouri Geological Survey. The integration method involves geometry comparisons between alluvium based soil units from the SSURGO dataset with stream lines from National Hydrography Dataset of The National Map and alluvium units from the bedrock geology maps. The consistency of this integration process is analyzed by comparing the confidence limits of best fit parameters to the null set of pattern shift. Results imply good consistency with this method for areas with well-defined stream lines and distinct geologic units.
