Creating a known point

If you are doing site/project work it will work just fine. The repeatability is what you’re looking for and as long as you have some kind of benchmark to tie your GCPs your map will be relative.

If you are doing property or other work that is recordable then it will depend on your municipality and whether or not the require true NAD83 or LLH coordinates.

I feel like there is another thread just like this?
