Process step:
Process description:
SSURGO data for Napa County and all surrounding counties was downloaded from the United States Department of Agriculture as shapefiles and a Microsoft Access Database. The shapefiles for Napa and all surrounding countines were merged and than cut using the Napa County boundary received from Napa County. The union command was than used to union the shapefile with the dataset showing evaluation areas recieved from Napa County.  A report of Prime Rangelands was produced from the Access database and exported to dbf format. The dbf containing information on prime rangelands was joined to the shapefile and the results were exported to a shapefile. The resulting shapefile containing SSURGO defined prime grazing lands was than re-classified into three classifications: high, medium and low. Upon direction of Napa County the lowest classification was thrown out to show only areas that contain the most prime grazing lands.  The Napa County land use layer was then used to extract areas which have been developed.  Developed lands include:  i) Lands classified as Urban/Suburban-Residential, Commercial, Industrial, Public/Quasi-Public, Parks & Public Open Space, ii) Lands that are Public/Quasi-Public-Vacant, Commercial-Vacant, and Industrial-Vacant on parcels less then 2 acres in size.
