Hillsborough County has developed a map atlas based on the U.S. National Grid so that federal, state, and local emergency responders can use a common georeferencing system in an emergency event. This map series are at three levels of scale and are in PDF file format. It is important that you shall not use any scaling or 'fit to page' when printing these maps so that scaling accuracy is maintained. The contents of this folder include the following:

A grid reader for measuring distance on multiple USNG map scales. To be printed 8 1/2 X 11 (No scaling).
