Extra Credit XVIII “GPS, Part II”

01 Jan

Extra Credit is video series that examines topics related to history in the Thunder Bay District and exploring that history. GPS can be a powerful tool for many types of applications.

For historical explorations, it can used in conjunction for satellite imagery and maps, both current and historic, to identify features that once existed on the ground. In this episode I demonstrate how I use Google Earth map overlay to identify points on old maps and then transfer that data to my GPS. Additionally, you will see how that process is validated once it is compared with the data that was gathered from the actual exploration.
