Handling time in geospatial information systems (GIS), the applicability of these valuable systems will increase, so, there hardly exist an application dealing with spatial information which can not be benefited from a temporal GIS. Despite many efforts undertaken since 1980, there is no generally accepted model which can satisfy all temporal GIS requirements. One of the most important problems...

The main objective of this study is to develop a prototype model of Web-based Geographic Information System (GIS) application for efficient management of borehole and geological data. More than 10,000 boreholes and other geological data were archived into the database and Web-based GIS system was implemented for a local urban area of Seoul in Korea. A standard form of borehole data was suggeste...

This paper introduces a Web Mapping system, UrMap, which incorporates new approaches for integrating GIS layers and Remote Sensing Imagery. UrMap is an on-line location-based service (LBS) website developed by OleMap Inc. in collaboration with the FORMOSAT-2 Image Application Distribution Center at National Taiwan Normal University and the National Space Organization (NSPO) in Taiwan. The goal ...

With the implementation of Earth Observation System (EOS), various technologies related to Earth Observation (EO) have been dramatically improved and extensively used. Geographical Information Systems (GIS) has also been developed greatly in recent years. Very few researches, however, have been done to integrate GIS and EO. Through analyzing some problems in the application of existing EOS and ...

The High Plains Underground Water Conservation District (HPWD) is the groundwater management agency responsible for a 6.8 million acre service area covering over 10,700 square miles in a 15-county region of West Texas. It is one of the oldest in the country and the largest of 88 such districts in Texas. Established in 1951 the HPWD managed their wells and permit applications using USGS quad map...

Public participation increasingly occurs in the context of modern GIS applications and goes much further than just crowd sourcing. Those web based applications enables the user to be actively involved in urban planning processes. Additionally, planners do profit from the participation of public. By the example of charging station for e-bikes, the participatory planning process is shown in this ...

Web GIS applications can be found in many domains. The quality of the interfaces of applications determines not only the usability of such applications, but the possibilities offered to their users. This work investigates aspects of interface quality for Web GIS applications. The approach adopts an inspection evaluation based on ISO 9241. Preliminary results show the effectiveness of such an ap...

A tool, based on a geographical information system (GIS) approach, has been developed for the location and organization of public health care centers in Jeddah city, Saudi Arabia. The potential of GIS for visualizing and modeling available information on health-care has been utilized to produce a "best-fit application". This paper identifies and deals with the manner in which GIS can successful...

GIS began as a highly specialized application of information technology, with its own hardware devices for input and output, its own data structures, and its own algorithms for data processing. Through time more and more aspects of GIS have become mainstream, and more and more standard approaches have been adopted to replace earlier specialized ones, taking advantage of the economies of scale i...

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...
