Coordinates transformation

Coordinates transformation transform single points, survey subprojects or the entire project between different cartographic or local systems.

• Click Survey.

• Click Transform by points.

  

• The command opens a new window.

  

• The first step is to define the type of transformation. On the left side of the window it is possible to choose:

  • Grid to Grid: transforms grid coordinates to other grid coordinates.

  • Geographic to Grid: transforms geographic coordinates to grid coordinates.

  • Grid to Geographic: transforms grid coordinates to geographic coordinates.

  • Geographic to Geographic: transform geographic coordinates to other geographic coordinates.

• The main panel shows the source system and the target system. Depending on the transformation mode selected we will have to enter the source and target system grid or geographic.

• Enter the source and target system. The software enter as default system in source the system applied to the current project.

• If the selection is a cartographic system, you can manually enter the parameters or click on Load predefined to load a predefined cartographic system.

• If the selection is local system click Details to open the calibration page to define the local system.

See Coordinate system for more information on the coordinate systems.

• In the Elevation system part, select the source and target elevation system. Here are listed available geoids.

See Localization package to download geoids from localization packages.

• At the bottom of the panel select which data to transform:

  • Transform survey subproject: transforms the coordinates of the active survey subproject.

    

  • Transform entire project: transforms the coordinates of entire project, including drawing, surfaces, etc..

    

  • Transform points: transforms a single point, entering the coordinate values.

    

• Click the Transform buttons to transform the points according to the entered parameters.
