    Your project there highlights perfectly why you (and anyone else including the LIDAR survey op) HAVE to prove your work with checkpoints. Understand that RMSE is a mathematical estimate. It can be a very good indicator of precision. But...

    I just want to add. You stated comparing mesh to the LiDAR. Compare the point cloud from your photogrammetry to the LiDAR point cloud. You can use Cloud Compare, it's free. Shift the LiDAR data to your data. Show the engineers your RMSE (I hope...

    What was your RMS? If your RMS as an example is 2 to 3 cm, the problem isn't your data, it's the older data. 0.64m is 64 cm and is not that high quality. How many check points were used in the LiDAR data? You can 100% compare data from...

    A mission of 4 sqmi (640 acres) would be close to 2.5 hours of actual flight time at 200ft AGL, so add the time it would take for multiple setups to maintain VLOS. Make sure to use real-time terrain following. Travel to and from the site, data...

    What is your friend hoping to get from this? Is this just for visualization of the property does he want absolute accuracy to include elevations for contours. Some points to think about Below 80 70 overlap (You can go lower, but with such a...
