HOW IT BEGAN
After becoming frustrated searching Google for a premade GCP that was durable enough to withstand the elements but also lightweight and portable, we decided to make our own Ground Control Points. We wanted to solve two main issues with our GCPs:
1. create a GCP that would not tear when a survey rod was placed into the middle of the target
2. create a GCP that would allow a surveyor to place wooden stakes for ground control ahead of time
