TERRA – SCAN, MODELER & MATCH

TERRA SOLID - MANAGING AND PROCESSING POINT CLOUDS


TerraScan
TerraScan is the main application in the Terrasolid Software family for
managing and processing all types of point clouds. It offers import and
project structuring tools for handling the massive number of points of a
laser scanning campaign as well as the corresponding trajectory
information. Various classification routines enable the automatic filtering of the point
cloud. Point cloud management, processing and visualization is only one part of
TerraScan. The results from the fully automatic classification can be refined by using half-
automatic and manual classification tools in combination with versatile 3D point cloud
visualization options.TerraScan supports several import and export formats, including the LAS and LAZ formats, TerraScan Binary and
TerraScan Fast Binary formats, as well as ASCII formats that can be defined according to the users’ needs.

VERSATILE TOOL FOR MANY KINDS OF DESIGN AND MODELING TASKS


TerraModeler
With TerraModeler you can create, edit, and utilize surface models. TerraModeler creates surface models (TINs) from
various sources, such as LiDAR points stored in binary files or loaded in TerraScan, XYZ ascii files and graphical design
elements. The software offers versatile visualization options including colored shaded surfaces, contour lines, grids, colored
triangle nets, elevation texts, slope directions and textured surfaces (in combination with TerraPhoto).

CALIBRATION AND STRIP ADJUSTMENT


TerraMatch
TerraMatch is a sophisticated tool for improving the accuracy and quality of the raw laser point cloud. It compares laser
data from overlapping flight or drive paths and calculates correction values for the misalignment angles as well as xyz
location errors. The comparison and correction value calculation can be either based on surface matching or on different
types of tie lines. Tie line matching comprises points or lines on horizontal, vertical or sloped surfaces that can be used
for matching flight/drive paths to each other, but also known point or line locations that enable the adjustment of the laser point cloud
to control measurements.
