This paper focuses on how to integrate the 3D data of 3D GIS and 3D CAD. This paper describes 4 approaches for the data integration, i.e. direct data import, shared access to database, formal semantic and integrated data management and file translation. Based on the last approach, this paper designs the scheme of data integration. This scheme focuses on two aspects: geometry exchange and the in...

Geographical Information System (GIS) technology has been an important tool in supporting urban planning and management for efficient accessibility to more, better, and timely information. This paper presents our research results of visualizing 3D city model in a web explorer environment under the supports of digital building model (DBM), digital terrain model (DTM), large-scale true urban orth...

In this chapter we will review some tools and open source Game Engines used for modeling of real scenarios in serious games for training. One of the typical uses of serious games (3D serious games) is specialized training in dangerous tasks or when the training is quite expensive. However, typical games use artificial scenarios, created by artists and created according to the restrictions impos...

The analysis of spatial variability of soils has been of interest to soil scientists and geographers for quite some time. Information on soil properties are usually available from a limited number of point measurements and spatial estimates are prepared in two dimensions (e.g. by interpolation or other technique). However, soil is essentially a 3D object with varying properties in all spatial d...

The real-time visualization of 3D GIS at a whole city scale always faces the challenge of dynamic data loading with high-efficiency. Based on the multi-tier distributed 3D GIS framework, this paper presents a multi-level cache approach for dynamic data loading. It aims to establish in 3D GIS spatial database engine (3DGIS-SDE) the unified management mechanism of caches on three levels, includin...

The increasing need and use of 3D GIS particularly in urban areas has produced growing attention on building reconstruction, which attempts to generate geometric and radiometric models of buildings usually from sensory data. The popular data used for building reconstruction are traditionally aerial or satellite images, more recently airborne LIDAR data, or the combination of these data. Extensi...

For several decades, Geographic Information Systems (GISs) have held center stage in archaeological studies of ancient landscapes. Recently, three-dimensional (3D) technologies such as airborne LiDAR and aerial photogrammetry are allowing us to acquire inordinate amounts of georeferenced 3D data to locate, map, and visualize archaeological sites within their surrounding landscapes. GIS offers l...

Conventional mine site investigation has difficulties in fostering location awareness and understanding the subsurface environment; moreover, it produces a large amount of hardcopy data. To overcome these limitations, the UMineAR mobile tablet application was developed. It enables users to rapidly identify underground mine objects (drifts, entrances, boreholes, hazards) and intuitively visualiz...

This paper presents the concepts and technology of GMN and its application in developing real estate management software. GMN abbreviating GIS+MIS+Network, is a new technology integrating Geographic Information Systems (GIS) and Management Information Systems (MIS) in the Internet environment. Previous real estate management software products which are mainly based on MIS cannot meet various es...
