Once you have defined a survey grid, you can convert between Latitude/Longitude and grid coordinates based on that grid.
If you know the grid coordinates, enter them. The Latitude and Longitude will be computed and displayed automatically.
If you have a survey point with the coordinates for which you want a Latitude and Longitude, enter the point label for Point.
If you know the Latitude and Longitude, enter them. The grid coordinates are computed and displayed automatically.
Enter Latitude positive=North, negative=South or include the letter N before or after the value for North or the letter S before or after the value for South.
Enter Longitude positive=East, negative=West or include the letter W before or after the value for West or the letter E before or after the value for East.
Choose this button to change the grid used to convert between grid and geodetic values.
When you open this dialog, TPC assumes you want to use the current survey grid. Most of the time, this is a valid assumption. If, however, you have individual points based on another grid, you can enter those grid settings and do the computations in this dialog based on those grid settings. The Grid settings you choose from this dialog do not change the survey grid. To change the survey grid, you must choose Tools | Transform Survey from the Traverses Manager or choose Tools | Survey Information, Grid.
