Recently, Web-based GIS applications have become important tools for disseminating geographical information in digital map format on the Internet because of their platform independence, interactivity, and wide accessibility. This trend brings about new insights on the integration of Web-based GIS and multimedia on the Internet since multimedia has already been seen as the strength of Internet a...

The increasing popularity of the Internet has led to the development of Web applications, known as Web GIS. A geographic information system (called GIS from now) is a software system that manages geo-referenced information. GIS systems are an automated system used for storing, analysing and manipulating geographical information. Geographical information represents objects and actions where geog...

The catalytic boost of critical mass usage of the World Wide Web (WWW) has brought about the shift in the traditional geographic information systems (GIS) paradigm and engendered new challenges and opportunities. The traditional GIS paradigm involves the use of huge databases and large expensive GIS software packages confined to local disks. The new paradigm, however, enables geospatial data to...

By introducing Web Services, distributed GIS(Geospatial Information System) services from different vendors can be dynamically integrated into a GIS application using the interoperable standard SOAP(Simple Object Access Protocol). However, it is debatable whether SOAP can really meet the performance requirement of GIS. Additionally, GIS Web Services’ performance may be improved by using asynchr...

One of challenges in GIS Web service is mass GIS data storage and processing. There are at least three obstacles that oppose dealing with this challenge: the mismatch between the frequent requirement of concurrent tasks for accessing data in GIS Web service and the poor performance of conventional storage mechanism such as relational databases; the insufficiency of relational databases to manag...

Open Source Web GIS software systems have reached a stage of maturity, sophistication, robustness and stability, and usability and user friendliness rivalling that of commercial, proprietary GIS and Web GIS server products. The Open Source Web GIS community is also actively embracing OGC (Open Geospatial Consortium) standards, including WMS (Web Map Service). WMS enables the creation of Web map...

The Open Geospatial Consortium (OGC) [1] defines a number of standards, both for data models and for online services, that has been widely adopted in the Geographical Information System (GIS) community. This has lead to a number of software development efforts, online data archives, and application communities. The emergence of Web Service technique overcomes the shortcoming of traditional Dist...

Web-based geographic information system (GIS) technology, or web-based GIS, offers many opportunities for public planners and Extension educators who have limited GIS backgrounds or resources. However, investigation of its use in planning has been limited. The study described here examined the use of web-based GIS by public planning agencies. A 2013 web-based survey of 274 public planning agenc...

BACKGROUND An extensive West Nile virus surveillance program of dead birds, mosquitoes, horses, and human infection has been launched as a result of West Nile virus first being reported in Canada in 2001. Some desktop and web GIS have been applied to West Nile virus dead bird surveillance. There have been urgent needs for a comprehensive GIS services and real-time surveillance. RESULTS A pilo...

Emergency management/Emergency service is a compelling domain for applying GIS Web Service. GIS Web Service expands the further development of GIS. A Web service is described using XML-standards like the WSDL (Web Service Description Language). Web Services, are different from Web applications, don’t require people to use; but software applications to call. Thus, the Web service does not have a...
