  Georeferencing Quick Reference Guide, Version 2012. Georeferenced to the approximate geographic center of Columbia Township within the administrative boundaries of Meigs County, Ohio. Used Google Maps - Earth and Map Views to locate the geographic midpoint of Columbia Township. Used the Google Maps - Measure Distance Tool to measure a straight line from the approximate geographic midpoint of Columbia Township, measuring to its furthest extent, then halved this distance to find the midpoint of the line. Used the Google Maps - Measure Distance Tool again to find the linear extent by measuring from the midpoint to the furthest extent of Columbia Township. (at: 39.116403, -82.314627) Input coordinates, coordinate precision (.00001 degrees), coordinate source (locality description), datum (WGS84), linear extent (7100 m), and measurement error (10 m) into the MaNIS Georeferencing Calculator to find the uncertainty radius.
