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...

In this paper we present a novel abstraction layer above the well-known triangular 1-to-4 split subdivision based on hexagons. This approach allows adaptive bidirectional subdivision, that is refinement and coarsening of the mesh, without causing problems like irregular refinement or hanging nodes. Thus it is feasible to adapt the mesh resolution locally, according to geometric features, viewin...

We present a new approach for managing the multiresolution representation of discrete topographic surfaces. A Triangulated Irregular Network (TIN) representing the surface is built from sampled data by iteratively reening an initial triangulation that covers the whole domain. The reenement process generates triangulations of the domain corresponding to increasingly ner approximations of the sur...

Gaits study is a fundamental part of legged vehicle research. Legged locomotion has been used by biological systems for hundreds of millions of years In contrast, wheeled locomotion vehicles have only a history of several thousand years. Wheeled vehicles are so familiar and ubiquitours in our modern way of life, and have been developed to such level of sophistication. But, approximately half of...

Self-transforming robot is a robot which transforms its shape according to the hindrance occurring in the path where the robots are being moved. Such robots have been recognized as very attractive design in exhibiting the reliable transformation according to the situations. Military and defense application needs a robot should possess arbitrary movements like human. In some scenarios transforma...

In this paper, the problem of creating a network to facilitate planning of an air reconnaissance mission is investigated. A comprehensive review of the literature shows that limited work has been done on the design of such networks in a hostile environment and that little research has accounted for terrain information. Ideally, in any routing problem a sample network is used as reference to det...

The two-dimensional (2-D) parabolic equation (PE) is widely used for making radiowave propagation predictions in the troposphere. The effects of transverse terrain gradients, propagation around the sides of obstacles, and scattering from large obstacles to the side of the great circle path are not modeled, leading to prediction errors in many situations. In this paper, these errors are addresse...

In this paper we show how to efficiently integrate traditional GIS data into terrain models in order to generate complete 3D maps with little overhead for textures. The results meet the requirements for the Web 3D Service (W3DS), a proposal for the standardization for delivering 3D web maps. Our approach is designed to create fully vectorized 3D scenes that deliver the best possible quality and...

1 The Digital Elevation Model that has been derived from the February 2000 2 Shuttle Radar Topography Mission (SRTM) has been one of the most 3 important publicly available new spatial datasets in recent years. However, the 4 'finished' grade version of the data (also referred to as Version 2) still contains 5 data voids (some 836,000 km 2) – and other anomalies – that prevent immediate 6 use i...
