Has anyone had any issues recently exporting .las file from TBC and them not showing up in the right spot in TBC?
Background:
- Flew various stockpile locations within a 20mile radius using a DJI M350 RTK.
- Processed each flight/stockpile location individually in DJI Terra with checkpoints for verification of 3D accuracies.
- Exported from DJI Terra to project coordinate system (NAD83 14N, CGG2013), note check points were also shot in that system.
- Point cloud data tied in decent from DJI Terra to other surveyed data that was imported to TBC (2023.11) via WorksManager.
- Filtered point cloud data and created surfaces that were comprised of point cloud data and surveyed breaklines.
- Exported all filtered stockpile point clouds as one .las file using the "Grid" option for export.
- Had another user open TBC (2023.11) on their laptop, load the WorksManager project into the drawing and import a .vcl that contained the processed breaklines.
- They then tried to import the .las file and they point cloud data was out not in the correct locations - correct ballpark location, off by maybe 5-10m.
- I then tried to export each stockpile/pit location individually using the same above method, thinking it had to do with a combined scale factor and the distance between each stockpile/pit location.
- Upon import of those files, they came in miles away from where they were supposed to be.
Not an issue for this particular project as I can simply create individual stockpile surfaces and export them as .xml file for them to create their drawings off of, but would be great to know for the future.
Thanks in advance!
