There are many applications involving featured terrains visualization. One of them is for gaming purposes. However, when dealing with real data, many of this applications fail to cope with such information. So, this work presents an efficient way to minimize or even remove this kind of problem. We propose a method based on image-based rendering and view-dependent visualization techniques. These...

The article discusses the construction of a digital terrain model in various programs, which will be used for vertical planning design. One major challenges this area is creation an accurate and realistic surface, give opportunity to create quality compliant site. To solve problem analyze, same territory initial data has been built. paper presents algorithms DTM method constructing irregular gr...

Current implementations of decentralized multi-robot construction systems are limited to construction of rudimentary structures such as walls and clusters, or rely on the use of blueprints for regulation. Building processes that make use of blueprints are unattractive in unknown environments as they can not compensate for heterogeneities, such as irregular terrain. In nature, social insects coo...

The main objectives of the study are: 1) To develop and test a mesoscale forecasting system with subkilometer horizontal resolution to support the NOWCAST system at the Fallon Naval Air Station (NAS); 2) To improve the accuracy of the forecasts and nowcasts by assimilating asynchronous data into the forecasting system; 3) To provide short-term predictions of cloud structure that are essential t...

Rectangularly sampled, or gridded, spatial data such as classified LANDSAT imagery and Digital Terrain Models (DTM's), are increasingly ubiquitous sources of cartographic information. For environmental analysis, gridded data must be related to point, line, and polygon descriptions of phenomena, such as highway networks and soil zones. In combining such disparate forms of data, analysts must con...

Images obtained by the High Resolution Stereo Camera (HRSC) and the Super Resolution Channel (SRC) on the European Mars Express (MEX) spacecraft have renewed the interest in Phobos, the larger of the two Martian satellites. We are involved in a comprehensive study in geodesy and cartography of this small irregular (13.4 x 11.2 x 9.2 km) satellite. We focus on astrometric measurements to refine ...

In this paper, radio wave propagation over irregular terrain is investigated in 200–600MHz (VHF/UHF band). Measured results are compared with different path loss models such as Fresnel knife edge diffraction and uniform theory of diffraction (UTD). It is shown that, for low antenna heights, using a combination of the two-ray path loss model and knife-edge diffraction, great improvement in path ...

In this paper it is proposed the extension of an efficient method employed for non-holonomic mobile robots to the path tracking of tractors with a trailer. The main advantage of this pure geometric technique is that no kinematic model of the vehicle is needed, which is an interesting property when working in irregular terrain or with tracks instead of wheels. The differences of applying this me...

Data conflation is a major issue in GIS: different geospatial data sets covering overlapping regions, possibly obtained from different sources and using different acquisition techniques, need to be combined into one single consistent data set before the data can be analyzed. The most common occurrence for hydrological applications is conflation of a digital elevation model and rivers. We assume...
