Pocket 3D software has a predefined projection list by default while installing and setting up the software. In case your region is not included in the predefined projection list, you have to add your local coordinate system as user-defined.
But, there is no option in Pocket 3D software to configure and create a local coordinate system as user-defined. This article explains how to create any local coordinate system as an XML file, which will be uploaded to the software folder.
With MAGNET Field, you can create any local coordinate system as an XML file and copy this file to Pocket 3D.
Open MAGNET Field.
From the main menu, click Configure.
Click Coord Sys.
Click on the 3 dots next to the Projection drop-down menu to enter your projection/coordinate system parameters.
Click on the 3 dots next to the Datum drop-down menu to select your datum ellipsoid or to create a new datum.
In the Custom Projection screen, enter the Name of your projection. Then select the Type from the drop-down menu.
Select your Datum ellipsoid.
Enter the name of your Region.
You can write any Note about your projection.
Enter the parameters of your custom projection.
Click the green check mark to save.
Now you have created your local coordinate system. You can select it and make it Active.
Your local coordinate system is saved as an XML file inside the MAGNET folder. Copy it to your USB drive.
Close MAGNET Field, and insert a USB drive in your field controller.
Open Windows File Explorer by tapping the Start menu, then open File Explorer. Go to this path:
- Program Files/MAGNET Field/Geo
Inside the Geo folder, you will find your local coordinate system (XML file) with the name:
Copy the userprojections files to the USB drive.
Insert your USB drive into the field controller.
Open Windows File Explorer with the Start menu, then open File Explorer.
Now, copy the local coordinate system (XML) file into the following paths:
- /Program Files/Topcon/Pocket3D/Coordsys/
- /Program Files/Topcon/Pocket3D/Coordsys/Projections
Open Pocket 3D.
From the main menu, click the Data button.
Navigate to Control > Options.
Click the Proj. tab to see your local coordinate system in the list.
Click the + sign to expand and select your coordinate system.
In the Coords. tab, you can select your Datum ellipsoid from the drop-down menu.
Now your local coordinate system is the current system in your current project.
