Historic Maps
 

 
T-Sheet example from Belle Fontaine, Jackson County.

Historic Maps are available from a number of different sources.  The scanned images are useful in highlighting changes to the environment over time.  Some maps do not have high spatial accuracy, but give a glimpse into what features were present and how they were perceived.  The historic T-sheets have been geo-rectified using previously digitized historic shorelines from the same maps.  These maps provide accuracy as well as perspective on the environment and are regularly used in scientific research.
