I have been using TBC to convert my GNSS Points from Grid Coordinates to Ground Coordinates using local site settings. This time however, my Project area is very large. The project area is 100km in length and 50km in Width. I usually used to take the centre of my project to key in the project location. But, for such large projects, is it ok to transform all the points using one single projection point somewhere in the centre of the project?
