Development of Three Dimensional Animal's Habitat Map by GIS

Three-Dimensional Map Building with MMW Radar

Radar offers advantages as a robotic perception modality because it is not as vulnerable to the vacuum, dust, fog, rain, snow and light conditions found in construction, mining, agricultural and planetary-exploration environments. However radar has shortcomings such as a large footprint, sidelobes, specularity effects and limited range resolution—all of which result in poor environment maps. Th...

Visualization of three-dimensional GIS objects using rapid prototyping technology

To build multicolored physical models of three-dimensional cartographic objects, such as city models, landscape with relief or conceptual surfaces, computer-controlled devices can be used which were developed for the fast and inexpensive production of mechanical parts. The main groups of rapid prototyping technology – aggregation, removal and, transformation – are presented, including the machi...

Developing Three-dimensional (3d) Topological Model for 3d Gis

3D spatial data modeling is one of the key research problems in 3D GIS. More and more applications depend on these 3D spatial data. Mostly, these data are stored in Geo-DBMSs. However, recent Geo-DBMSs do not support 3D primitives modeling, it only able to describe a single-attribute of the third-dimension, i.e. modeling 2.5D datasets that used 2D primitives (plus a single z-coordinate) such as...

Map Revise Technique by Using Collaboration of Gps and Gis

Much local government has been utilizing the large scale digital map with Geographic Information System (GIS). GIS will be able to efficiently work and to reduce mapping costs. However, the maintenance and renewal of a map database need much labor and time. However, the updating method of a map is not established yet and, there is little successful example. The purpose of this study is establis...
