Convert Ground Coordinates to Grid Coordinates given a GAF (a.k.a. combined factor)

Convert Grid Coordinates to Ground Coordinates given a GAF (a.k.a. combined factor)

Calculate a GAF given Ground Coordinates and Grid Coordinates. This utility is useful when reviewing plans that omit a GAF when both sets of coordinates are provided.

Compare two GAFs for a particular project. This is useful when comparing published GAF on NGS Data Sheets and a local GAF shown on design plans. You can set the distance that you want to use as a baseline for comparison

This app is simple and only calculates one pair of coordinates at a time for quick checks when reviewing survey maps and drawings.
