Add a new control point

The Local tab on the Control point screen is where to add the control points from a project. One control point from a GPS measurement can also be made there. Select Control Point to add a control point from an existing project file.

The WGS84 tab shows the selections to get one GPS measurement. This automatically enters the latitude, longitude, and height. WGS84 is recommended for a small project site in which 1-point localization is necessary.

The Grid tab can show, not the WGS84 tab. To replace Grid with WGS84, select the Coord. system tab to change the control point to GPS localization.
