Hello TBC’ers! Today we’re talking about how to validate your drone data with background maps and the Reference Image Viewing Distance property in TBC. This is the easiest way to ensure your photogrammetry data is accurately imported and aligned with your area of interest. With TBC you can quickly verify that your drone data is correctly geo-referenced and positioned within the project area, identify and correct any misalignments or data import errors early in the workflow, and understand the spatial context of your project.
To begin this workflow follow these steps:
-
Import your drone data set into a defined geo-referenced coordinate system.
-
Enable a background map in the Home tab by clicking on the "Trimble Maps” drop-down under the View group. In this drop-down select “Satellite”.
-
If you set the reference viewing distance of your drone images to the flight height of your collection, you can see how closely aligned your drone imagery is to your target area. To change the size of the reference images in your project, go to the Project Settings > View > Referenced Image > Viewing distance. Then, click in the selection box and change the viewing distance to the flying height*.
*If you do not know the flying height of your project you can find it in the Flight Mission Adjustment Report. Be sure to subtract the terrain height from the flying height for the most accurate results.
-
In this case, the reference image viewing distance was set to 100m. You can see that the satellite background image aligns with the drone imagery.
And that’s it! By overlaying your drone data on Trimble Maps, you can visually confirm that your data is correctly imported and positioned, ensuring accuracy for your project.
You’re all set! Maximize your TBC experience and ensure smooth workflows by utilizing learning & support material most aligned with your needs and personal preferences.
