Le manque d'informations sur la fiabilité des données acquises durant le vol constitue l'un des problèmes majeurs des systèmes laser aéroportés (ALS) actuels. Des erreurs ou des dégradations inacceptables de la qualité des données inertielles puis le géoré ...
One of the main problems of today’s Airborne Laser Scanning (ALS) systems is the lack of reliable data quality assessment within or shortly after the airborne survey campaign. This paper presents the development and implementation of a tool that allows com ...

A flexible quality-monitoring tool that assesses data quality in-flight avoids costly problems that are currently detected only in post-processing. ...
This paper describes the goals, concept and overall approach of the European 7th Framework Programme´s project named CLOSE-SEARCH, which stands for ´Accurate and safe EGNOS-SoL Navigation for UAV-based low-cost SAR operations´ and is being conducted by a c ...
This paper presents a methodology for the precise registering of airborne laser data directly in flight with an accuracy that is sufficient for the majority of derived products, such as digital terrain models. We first present the strategy that integrates ...
The quality of the laser point cloud georeferencing in airborne laser scanning missions is largely related to the quality of the GPS solution. The latter is obtained by post- processing the differential carrier-phase measurements in order to reach the requ ...
