Every mapper has struggled with a map that for some reason doesn't align properly. Your different layers of base data aren't anywhere close to each other or you've shown up to do your fieldwork but your gps is several km from where it should be. This 2.5 hr course has been specifically designed to give you the knowledge to avoid these issues or troubleshoot them when they do arise. In the course you will learn all about coordinate reference systems, the earths magnetic field, declination, grid convergence, and grivation, and more.

Upcoming classes: There are no scheduled classes. If you would like to request a class, email jeff@navigationsports.ca
