In the analysis of terrestrial laser scanning (TLS) data the digital terrain model (DTM) is one of important elements. To evaluate the DTM or to find the DTM by way of optimization it is necessary to formulate the measure of DTM quality. Three parameterized measures are proposed and tested against a comparative model for a series of TLS data. The measure equal to the number of points inside a l...

Distributed Transactional Memory (DTM) is an emerging approach to distributed synchronization based on the application of the transaction abstraction to distributed computation. DTM comes in several system models, but the control flow model (CF) is particularly powerful, since it allows transactions to delegate computation to remote nodes as well as access shared data. However, there are no exi...

A comparison between data acquisition and processing from passive optical sensors and airborne laser scanning is presented. A short overview and the major differences between the two technologies are outlined. Advantages and disadvantages with respect to various aspects are discussed, like sensors, platforms, flight planning, data acquisition conditions, imaging, object reflectance, automation,...

Cartosat-1 is the eleventh satellite of the Indian Space Research Organisation series and is primarily meant for topographic mapping and Digital Terrain Model (DTM) generation. In the framework of the Cartosat-1 Scientific Assessment Programme, the Politecnico di Milano University (Italy) evaluated as Co-Investigator the performances of the Cartosat-1 satellite in the generation of DTMs. This p...

This paper elucidates the potential of LiDAR data for information generation for security applications. The study is embedded in the EU Network of Excellence GMOSS. General, security applications cover a large area from infrastructure monitoring (e.g. power stations, pipelines) or border monitoring to less tangible threats like terrorism and civil security / homeland security. It is demonstrate...

Comet is an interactive visualisation tool, which supports real-time visualisation and exploration of very large Digital Terrain Models (DTMs) on commodity workstations. Comet is designed to be portable across a range of different hardware architectures and network environments, and has been implemented using a novel combination of standard software components. A tile-based Distributed Shared M...

Digital terrain model (DTM) generation is the fundamental application of airborne Lidar data. In past decades, a large body of studies has been conducted to present and experiment a variety of DTM generation methods. Although great progress has been made, DTM generation, especially DTM generation in specific terrain situations, remains challenging. This research introduces the general principle...
