Geo-Information Extraction with Laser Scanning


International training course on Geo-Information Extraction with Laser Scanning

2-6 November 2015 at Space Krenovation Park, Sriracha, Chonburi, Thailand

Course Content

Airborne, terrestrial and mobile laser scanning are modern technologies to acquire and monitor the geometry of the Earth’s surface and objects above the surface like buildings, trees and road infrastructure. This course provides an overview on the state of the art of these techniques, potential applications as well as methods to extract geo-information from the recorded point clouds.

This course provide:

  • Introduction: principles of airborne, terrestrial and mobile laser scanning, properties, accuracy potential, comparison to other data acquisition techniques, overview on various applications.
  • General processing of point clouds: visualisation, segmentation of point clouds, error sources and correction methods, quality analysis. Digital terrain models: extraction of terrain points and break lines.
  • Detection and modelling: 3D building reconstruction, extraction of vegetation characteristics, change detection with multi-temporal and single epoch data for map updating, land slide analysis, and mobile mapping for road inventory.


This course will build capacity in laser scanning technology, image processing, and its applications as well as strengthen international, in particular regional cooperation.
