There are many different ways of applying GPS tools to Keyline Design. On a small site (5-7 acres) you could do something as simple as using a cell phone GPS to locate waypoints from a map to the actual site. Cell phone GPS is only accurate to 3ish feet. On the high end, an RTK GPS-enabled topographic survey can provide a highly accurate landform map for designing your farm (sub-1 inch accuracy!).
We're covering many different use-cases for these tools in the workshop...and making it super-simple to implement.
ONLINE version for those that want to study at home too!
