Ground targets for horizontal check for LIDAR data collection

An important evaluation to make when performing a QAQC analysis of a LIDAR data set is a control point comparison. Typically, this refers to checking the vertical accuracy of a LIDAR data set. In regards to vertical check/control point location: “Unlike horizontal checkpoints, vertical checkpoints are not necessarily required to be clearly defined or readily…

Trajectory Accuracy Estimates

TerraMatch allows for the correction of data that has position errors that vary over time, for example mobile data that was gathered in downtown areas with GPS drop-out. This is accomplished by computing tie line fluctuations that compute a correction curve along the trajectory to account for positional uncertainty. Each discrete position along a trajectory…
