The TinyMobileRobots Surveyor App supports importing of projection files. This gives you an option to import your own projection, when you can't find the projection you're looking for via search bar on the in-App library ( See Importing Job Files: How do I Select the Right Projection?...)
We support import of .prj files containing WKT or WKT 2 proj-string text
WKT and WKT 2 proj-string text can be found at EPSG.io
For more info on creating a .prj file, please see How to create a basic .prj projection file...
Step 1
Connect your TMR tablet to a computer via USB and copy over your .prj file to the tablet's internal memory. Try to remember which folder you put the .prj file in.
Step 2
Navigate to Settings > Position > Manage projections on the App
Press the Edit projections button
Step 3
Press the Import button
Step 4
Navigate to the folder where you copied your .prj file in step 1 and select it from your tablet's internal memory
Step 5
You can now view and edit the details of the imported .prj file
1 - Edit the name of your projection
2 - Give the projection a description
3 - View and edit the proj-string
4 - Press the 'Save' button to save the imported projection
5 - Press 'Cancel' to stop the import process
STEP 6
You will now see your newly saved projection in the 'Edit projections' menu and have successfully imported your .prj file
Step 7
Return to Settings > Position > Projection
Type the name of your imported projection file into the search bar and select it from the drop down list
You should notice that projections imported via .prj files will appear as 'Custom:xxxxx' once selected
Press the 'Apply projection' button to use your imported projection
The applied projection will appear on the 'Recently used' list with a green button beside it
