Transform Survey Dialog

This dialog transforms the survey coordinates from the current survey grid (From box) to another grid (To box). Once the transformation is complete, the settings in the To box become the current survey grid settings and are stored with the survey the next time it is saved.

To change the survey grid without changing the coordinates, choose Tools | Survey Information, Grid.

From - Grid, Zone, Grid Factor, Ellipse, Feet to Meters

These are the current survey grid settings. When transforming the entire survey, you will not change these values. In fact, doing so will cause the transformation to compute erroneous coordinates.

TPC allows you to change these settings so that you can change selected imported traverses from whatever grid they are on to the current survey grid.

To - Grid, Zone, Grid Factor, Ellipse, Feet to Meters

Choose the desired grid settings you want to transform the survey to. Once the transformation is complete, the grid settings in the To box are stored with the survey as its current grid settings.

Transform What

All - transform the entire survey.

Selected - transform just the selected traverses.

Converting Imported Traverses to the Survey Grid

At times, you might also import data based on one grid and want to convert it to the survey grid. TPC lets you specify the grid settings for those traverses and convert them to the same grid as the survey. The steps are explained in the Coordinate Transformation topic.
