You can use TerraScan-Lidar Data Processing Software in corridor and areal mapping projects. The most deadly thing about Lidar data is huge number of laser points. Your windows operating system may bang during data processing, one of the major cause is exceed memory limits. To avoid such circumstances, TerraScan Software let you divide data sets into smaller geographical blocks which can handle easily by Microstation tools.
The Lidar Data Processing will take place by some steps. The first round of processing will take place by user define macros. After completion of this automatic process, all points are segregated into different classes like ground, vegetation, trees and buildings. Automatic processing is fantastic for most of the cases, but sometime we need to run manual classification as per our project process document. Its manual Lidar Data Processing also very user friendly.
TerraScan reads-in raw laser points as XYZ text files or binary files like LAS and TerraScan binary.
The key-features of TerraScan - Lidar Data Processing Software are as follows:
