Airborne Laser Scanning, Elevation Models and True Orthophoto Mosaic of the Saxon–Bohemian Switzerland National Park Region from 2005

Abstract

The digital data has been created during an INTERREG IIIA project in the period from January 2004 up to December 2006. The main task of the project is the planning and finalisation of activities to create a homogeneous geographic data set including high accuracy topographic and optical data for the whole cross-border national park region Saxon- Bohemian Switzerland. Data acquisition was provided using one sensor system without splitting the region into several parts. Laser scanner data with a minimum of 1 measurement point per square meter and 50% overlap across flight direction, colour infrared and RGB imagery have been collected simultaneously. After the successful finalisation of data acquisition all the data was processed in order to produce high quality digital terrain models (DTM) and high resolution true ortho imagery mosaics. The data acquisition has been taken by TopoSys GmbH (Biberach, Germany) in Spring 2005 using the FALCONII sensor system. The mission was flown in March in the period from April 14th, 2005 to May 1st, 2005 (16 flights on 11 days). The true ortho imagery mosaic was completely created by TopoSys.
