Grid to Ground Conversion?
Posted by bill survey
I am running a large (for me) traverse of about 15,000 linear feet. I have four pairs of GPS along the way. My plan is to hold one of the GPS points (near the center of the project) grid position and scale the other GPS points to ground from there, by averaging the CGF provided by OPUS. What's the best way to apply this factor? Should I use the grid azimuths and apply the computed scale factor on that same azimuth, for each point? Or should I scale the Northing and Easting by the same computed factor?
