The inclusive Web-based Public Participation GIS (WPPGIS) domain has developed from the interactions of three principal domains: Public Participation (PP), Internet and GIS. Each two domains create distinct sub-domains: PPGIS, Web-based PP and Web-based GIS, each of which has been researched in its own right. A successful WPPGIS utilizes the dominant properties of the above sub-domains to creat...

Mobility is an emerging concept in the GIS (Geographic Information Systems) domain and according to some specialists it will introduce a revolution on the way GIS users interact with their data. With this paper, we propose a system architecture for a global, fully mobile and location based GIS system, creating an abstraction to support generic multi-level geo-referenced data, from satellite ima...

An effective three-dimensional (3D) data representation is required to assess the spatial distribution of the photovoltaic potential over urban building roofs and facades using 3D city models. Voxels have long been used as a spatial data representation, but practical applications of the voxel representation have been limited compared with rasters in traditional two-dimensional (2D) geographic i...

In order to provide the seamless navigation and positioning services for indoor environments, an indoor location based service (LBS) test bed is developed to integrate the indoor positioning system and the indoor three-dimensional (3D) geographic information system (GIS). A wireless sensor network (WSN) is used in the developed indoor positioning system. Considering the power consumption, in th...

With the development of the economy, the fast and accurate extraction of the city road is significant for GIS data collection and update, remote sensing images interpretation, mapping and spatial database updating etc. 3D GIS has attracted more and more attentions from academics, industries and governments with the increase of requirements for interoperability and integration of different sourc...

Construction site managers could benefit from being able to visualize on-site construction objects. Radio frequency identification (RFID) technology has been shown to improve the efficiency of construction object management. The objective of this study is to develop a 3D-Web-GIS RFID location sensing system for construction objects. An RFID 3D location sensing algorithm combining Simulated Anne...

Engineering excavation GIS (EGIS) is a real-3D GIS serving for geosciences related to geo-engineering, civil engineering and mining engineering based on generalized tri-prism (GTP) model. As two instances of GTP model, G-GTP is used for the real-3D modeling of subsurface geological bodies, and E-GTP is used for the real-3D modeling of subsurface engineering excavations. Based on the discussions...

Building Information Modelling (BIM) provides a detailed 3D geometrical model with rich semantics which go beyond the standard Computer-Aided Design approach. In contrast, Geography Information Science (GIS) offers powerful spatial analytical tools. This paper seeks to propose and innovative research approach integrating some aspects of BIM and advanced GIS analysis. This may lead into beyond s...

Terrorist attacks at the World Trade Center (WTC) in New York City and the Pentagon on September 11, 2001, not only affected multi-level structures in urban areas but also impacted upon their immediate environment at the street level in ways that considerably reduced the speed of emergency response. In this paper, we examine the potential of using real-time 3D GIS for the development and implem...

The damage scale and damage area in the coast have been increased dramatically because of calamities such as typhoon, tidal wave, flood and storm. Especially, 409 cases, which reach to about 40.9% of natural disasters of 1,000 cases for the recent 15 years have happened on coast area. More than 40% of natural disasters also occurred every year is happening in coastland. Therefore, there is a gr...
