Internet, a client/server system, is a perfect means of GIS data accessing, analyzing and transmission. The World Wide Web, FTP (file transfer protocol) and HTTP programs make it convenient to access and transfer data files across the Internet. Using Internet for GIS makes it easy access to acquire GIS data from diverse data sources in the distributed environment. The geospatial multicriteria d...

Natural disaster mitigation is a collective effort of; forecast, assessment, and encouraging the public participation in disaster mitigation. This study focused on the rarely addressed aspect, “the value of public awareness” in natural disaster mitigation. The methodology used satellite data and Geographic Information Systems (GIS) to produce semi-real-time “Media GIS” contents. When deliver th...

Spatial analysis is a fundamental function for geographic information systems. Although it is popular in many commercial desktop GIS packages, this capability is very limited in a Web-GIS environment, especially when relational database is used for geospatial data management. This paper proposes and prototypes a methodology to enhance spatial analysis capabilities of Web-GIS by extending and en...

The purpose of this study is to develop an information system (AR recommended GIS) to support tourists’ excursion behavior by making the accumulating, sharing, and recommending of information concerning urban tourist spots possible. The conclusion of this study can be summarized into three points as shown below. (1) In order to support tourists’ excursion behaviors by integrating SNS, Twitter, ...

This paper has proposed GML-GIS, which is a prototype system for geographic information service over the Web based on GML (Geography Markup Language). This system generates geographic information into GML document by user requests through URL and provides them with various styles applied to the document on the Web browser. This proposed system converts geographic information of a spatial databa...

Building consensus over the set of alternative solutions in a spatial decision making process promotes the sustainability, stability and longevity of spatial decisions. Web-based GIS–MCDA (Multicriteria Decision Analysis) facilitates consensus-building in the process of spatial decision making. The level of consensus among decision makers in the Web-based GIS–MCDA can be influenced by various d...

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...

The paper addresses current research issues in the field of interoperability of heterogeneous GI systems. Special emphasis is placed on heterogeneity at the level of conceptual data models. This problem is discussed in the context of cross-border web-based GIS applications which involve the combination of spatial data on the same type of real world objects from different countries. Existing app...

A Web-based Geographic Information System (Web-GIS), the SIGNe (Système d'Information Géographique pour la Néphrologie), was designed for the Renal Epidemiology and Information Network (REIN) dedicated to End-Stage Renal Disease (ESRD). This Web-GIS was coupled to a data warehouse and embedded in an n-tier architecture designed as the Multi-Source Information System (MSIS). It allows to access ...
