Apply Correction is Very Slow

Symptom: Applying tie line fluctuation corrections using TerraMatch, either on loaded points, project points, or by using the Apply Corrections macro step runs very slow. Probable Resolution: Apply correction takes a long time if the points are not sorted by time stamp. The Apply correction process computes the scanner position for small intervals of consecutive time…

Intensity Custom vs Automatic Coloring

Color by Intensity custom/auto settings display the points according to their intensity value. The default grey scale of TerraScan stretches from dark grey for low intensity values to white for high intensity values. Intensity auto uses a more homogeneous grey-scale coloring scheme. The intensity values are fitted to the grey values of the coloring scheme…

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…

XY Swap Transformation

Sometimes customers will receive LIDAR data that has the X and Y positions in the wrong order in the data file.  Because of this, the data will appear inverted and out of position once it is read into TerraScan. There is an easy way to correct this using a transformation in TerraScan Settings. In older,…
