Applies to: Desktop Processing software version 2.11.0 and higher
Using the wall or ground control points (GCP) for post-processing is a great way to optimize the SLAM trajectory and remove drift from the data.
Before post-processing, you need to input (e.g. in SiteMaker) a .txt or .csv file containing all the measured control points.
Range of control point values
The accepted range/limit of the control point values is 20,000 meters if the data is to be used later in IVION (since v. 2.11, July 2021).
More details from the following docs:
Changelog: Version 2.11.0
How to Use Control Points: Creating the Anchor Poses File - M6 and VLX
Previously (before mid 2021) the limit was 10,000 meters.
