3
Working on a Local Grid Point 1Point 2 UTM X 562, , UTM Y 3,245, ,246, Local Grid X 10, , Local Grid Y 10, , You need two points in your area where you know: X-Y on your Local Grid X-Y on a normal HYPACK ® Project Grid, such as UTM, State Plane, UKNG, etc.

4
GEODETIC PARAMETERS: Setup for Local Grid Set GEODETIC PARAMETERS to a Grid/Zone that HYPACK knows about (e.g.: UTM). Next, change the Grids entry to None. Click the Local Grid Adjustment check box and then the Local Grid button.

5
LOCAL GRID: Window Enter the World and Local coordinates, select your origin and have the program compute the rotation, translation and scale.

6
Local Grid: Example Point 1 UTM X562, UTM Y3,245, Local Grid X10, Local Grid Y10, Point 2 UTM X563, UTM Y3,246, Local Grid X10, Local Grid Y11,

7
Checking it in GRID CONVERSION Point 1 UTM Zone 17. X = 562, Y = 3,245, UTM Lat-Long: Lat = N29° Lon = W80° Local Grid Coordinates X = 10, Y = 10,
