Project height

The project height can be defined as part of the coordinate system definition when creating a new job. Enter the project height in the Project height field of the Coordinate type tab of the Coordinate system definition dialog.

If a project height is required and has not been defined when click Save in the Coordinate system definition dialog, you are prompted to enter a Project height value.

If a point has no elevation, the Trimble Access software uses the project height in Cogo calculations. If you combine GNSS and 2D conventional observations, set the Project height field to approximate the height of the site. This height is used with 2D points to calculate grid and ellipsoid distances from measured ground distances.

In 2D surveys where a projection has been defined, enter a value for the project height that approximates the height of the site. You need this value to reduce measured ground distances to ellipsoid distance, and to compute coordinates.
