Vectorize Rails, Wires, and Compute Track Geometry

Review these results of a TerraScan project that uses tools to automatically vectorize rails, wires, and fit geometric components to a breakline derived from the as surveyed rails. Railroad toolbox – Used to place lines, to fit lines to classified points along rails, to find rails and overhead wires automatically, and to check end points…

Analyze and Design Road Surface Improvements

Review these results of a TerraScan project that uses tools to analyze and design road surface improvements. Define color points – On-the-fly extraction of color values for each point, display of the point cloud. Draw Sight Distances – Determines how far a viewer sees along a road, railroad, or other corridor, and produces labels for…

LIDAR in Railroad Maintenance and Safety Analysis

The purpose of this animation is to illustrate a few railroad track maintenance and safety related factors. Download the presentation from Intergeo 2018. Draw Sight Distances – Potential obstacle search is defined as a constant value in the tool’s settings. Find Danger Objects – Finds points which are within a given distance from vectorized wires.…

Analyze Road Environments with Rotating Multi-Beam Laser Scanner data

As the use of multi-beam rotating scanners becomes increasingly popular in mobile mapping, a growing interest has been noticed for an animation about using Terrasolid tools to process such data sets. This animation shows some Terrasolid tools developed to analyze road environments. The part showing computing the road section parameters includes a comparison with a…
