Title: GPS Grid to Ground options
Created: 0000-00-00Last modified: 0000-00-00

This is in regards to using SurvCE Version 6.02 or higher to scale your GPS equipment to Ground Distances.

***Please Note: It is most common to use a Multipoint Method of "Plane Similarity" and to add 4 to 6 control points around the outside of the project area in the Points tab.  This Automatically Calculates your grid to ground scale factor for you in which case NONE of the information in this Article applies.


1)  Applying a Grid to Ground Scale Factor without a Rover Localization
Basic Grid to Ground conversion


2)  Using a "2 point Rotate Only" Localization scaled to Ground
2point Grid to Ground


3)  For using a 1 point Localization with assumed Local Coordinates scaled to Ground {i.e. - Northing of 5,000 + Easting 10,000 + Elevation 900}
1point Grid to Ground
