These layers are sorted into 6 Data categories; Land data (physical features as data layers), DXF Files (Addresses, streets, etc..), Transportation (Layer concerning transportation like railroads), All Files (Everything available), Election Data (Precincts), Imagery (Satellite imagery of Delaware county)
(Really blurry for some reason, but contains Parcels, Hydrology, and Street Center Lines of Delaware)
