Compare GCPs to ground-classified points only when GCPs are located in vegetated areas
When GCPs are located under vegetation, such as under a forest canopy, it's recommend to enable "Compare GCPs only against ground classified points" in SpatialFuser: This will ensure that GCPs are compared to a TIN surface made from only ground ...
Fixing an incorrect IMU orientation in SpatialExplorer
Fixing an incorrect IMU orientation in SpatialExplorer IMU data is relative to the IMU's own coordinate system (specified by the manufacturer), so to get IMU data in vehicle frame, we must know how the IMU is oriented in respect to the vehicle. The ...
Which antenna model do I select in SpatialExplorer or LiDARMill?
There's several steps in the lidar production workflow where it is necessary to specify an antenna model, either in SpatialExplorer and LiDARMill. Selecting Reference Station Antenna Model When importing reference station data into SpatialExplorer, ...
Static Alignment vs Static Time
Static alignment and static time are two concepts that are frequently confused. Many lidar systems cannot statically align their gyroscopes, but all lidar systems still benefit from time spent statically at the beginning and end of a data ...
Does your NavLab pipeline fail when you select the Automatic dynamics model option?
Why does NavLab fail to process sometimes? This can be for several different reasons including, but not limited to, unideal vehicle dynamics, reference station data issues, etc. One method of troubleshooting is to select a dynamics model other than ...
