            Thinly-soiled and depressional karst features were mapped in Schoharie County, NY in order to provide agricultural planners maps of manure-sensitive areas.  This mapping is needed to help farmers comply with the New York State DEC guidelines for managing manure in karst settings.  The study used 1 meter resolution LIDaR hillshades to digitize depressions and karst features.  This set of features was then analyzed with Bedrock Geology, Surficial Geology, Soil (SSURGO) data, hydrography data, and Brittle fracture data to classify features into 2174 Definitely Karst, 412 Not Karst (Glacial or Anthropogenic), and 2775 Possible Karst categories.  A random subset of 198 of the mapped Possible Karst features were analyzed with high resolution true color oblique imagery in order to reclassify each into Definitely Karst, Glacial or Anthropogenic.  Field surveys were conducted at 150 sites.  Ground Penetrating Radar (GPR) profiling was implemented at 17 sites, representing the most common combinations of soil, and geology factors.  GIS maps were prepared of these features, along with areas where carbonate bedrock is likely within four feet from the surface.  GIS maps of 100 and 30 foot setbacks were prepared for thinly-soiled karst areas.

            Google Earth KMZ files were created from this mapping so planners can view and work with this mapping directly in the field.  This is accomplished using the GOOGLE EARTH and GOOGLE DRIVE applets available for most cellphones.  This process uses the smart phone’s inherent GPS capability to plot exactly where the planner is in the mapping as he or she walks around.  Detailed instructions for how to accomplish this are presented below.
