Collaborative Marking GCPs

This chapter introduces you how to mark GCPs on multiple computers simultaneously.

For a large number of control points in a project, Get3D Mapper supports multiple computers to mark GCPs together to enhance work efficiency.

Collaborative Marking GCPs

Get3D Mapper supports opening sub-projects on multiple computers, and the only operation that sub-projects can do is to edit control points.

When the main project enters the interface of editing control points, it locks all control points by default.

When the main project releases a portion of the control points, the secondary project can lock that portion of the released control points and perform Mark GCPs operations. When multiple computers have finished collaborating on the marking, click on each computer to save the control point information.

Finally, the main project will update the control point information.

Operation Pricinple

The specific operation is as follows:

1) In the main project in the submit AT interface click Edit GCP to enter the Edit Control Points interface. Import the control point file and select the correct coordinate system.

2) Select some control points and click Unlock.

3) Open the project on another computer. When you open it, the default prompt is that the project opened here is a sub-project, and you can only edit control point operations.

4) Enter the Edit Control Points screen, click Update to see the unlocked control points, and then you can Mark GCPs on the machine after locking it.
