Hocking County, Ohio Maps and Drafting Department

This site offers maps in .pdf and .tif graphic formats, as well as data in shapefile and .dwg formats. The .dwg maps are of USGS quadrangle topo lines, and of property parcels by township. .pdf files are of property parcels by township, school districts, and maps of the county and Logan. .tif files are of property parcels by township and by city, subdivision maps, and miscellaneous other maps. Shapefiles are of roadway centerlines, property parcels by township, and benchmarks. This site also offers links to download viewers for .dwg files (these are CAD-system type files, and can usually be easily converted to shapefiles). The site simply provides the directories, and the computer user must choose the file and download it, often without much explanation.
