Hello,
I am studying the new ASPRS guidelines, version 2, published in 2023. I am stuck with an equation prescribed for estimating the horizontal accuracy of a LiDAR dataset using the error values published by the GNSS and IMU manufacturers.
In the equation for Horizontal RMSE, there is a scaling term (1.478) used for the IMU errors. This is different in the two different versions of the guidelines. I'm attaching screenshots of both the equations as well as the link for the two documents.
If anyone who's an expert in this subject can please provide me with some insight as I'm really stumped with this.
ASPRS guidelines version 1, 2014: https://shorturl.at/aHM36 page no A7
ASPRS guidelines version 2, 2023: https://shorturl.at/s5679 page no 16
If I need to provide further information, I'm happy to do so.
