Recently, local governments have started projects of implementing Geographic Information Systems (GIS) as an infrastructure for the collection, storage, and analysis of the spatial information. So far, these projects have been approached from the areas such as the civil engineering and the computer science perspectives. Nonetheless, in order for a GIS project to be successful, it should be approached from the management perspectives as well. In this paper, the authors discusses about the management issues such as the determination of priority of the sub-projects, the organizational structure that takes charge of the project and the evaluation of the performance of the project.

At present, GML becomes the global standard for the XML encoding of geographic information and is the foundation for the Geo-Web. GML is being applied to a wide range of geographic applications including GIS and location-based services, telematics and intelligent transportation systems. In this paper, we propose the tourism information system for supporting the location based service application. We made an effort to design and implement a GIS computing environment by thin client for mobile web mapping service. We are interested in the GML applications that include traditional GIS system for navigation service and location finder for points of interest (POI) services. This paper summarizes the Tourism information system for location based service of a small area (Han-Ok Village with the Korean traditional houses in Jeonju-city), in which moving travelers can obtain proper information services at the current location associated with traditional monuments, cultural products, food, and conveniences. In the paper, we report on the design of the thin client/server system for a mobile environment. This paper is divided into three parts. First, we give a general overview of the organization of the system and of the important concerns of our design. Second we focus on our system supports for location and POI determination, and design concerns. Finally, we show the graphic user interface of PDA, the procedures involved in the service, and the executed results.

The maturation of the Web technology has reshaped the ways in which data are accessed, disseminated, and shared. Thanks to its popularity along with the advance of spatial information technology, four major changes have been further made in traditional geographic information systems (GIS) in relation to access to data, distribution of data, access to GIS functionality, and visualization of multimedia data. Although access to and dissemination of spatial data over the Web has in recent years been addressed in the literature, little research effort has addressed the issue of access to and processing of GIS analysis functions over the Web. This research explores the potential use of Web-based GIS in improving accessibility to distributed spatial data and spatial modeling tools. A prototype Web-based GIS developed in this study focuses on Web-based location-allocation modeling for spatial decision support, and employs a hybrid approach that uses the Arc/Info software as a GIS server and CGM viewer as a client-side plug-in. This research shows that Web-based GIS is a useful vehicle in conducting spatial modeling in the particular user community. In addition, this study represents the possibility of Web-based GIS in developing open spatial decision supporting systems.

Since the mid 1990s, in response to rapid changes in Geography subject. Geographic Information Systems (GIS) has been in central position in the UK geography curriculum. This paper discusses the roles of GIS for Geography subject curriculum and addresses main development within UK Geography curriculum since the 1990s, and investigates appropriate GIS curriculum that encourages teaching and learning of geography subject within the curriculum. To obtain these research purposes. this paper starts with the brief description of the Geography subject in the National Curriculum for England (1998) with the recent changes of Geography subject in the national exams (GSCE and A level) in the UK. This result represents a clear situation of Geography subject in the UK school education and also provides a new motivation that brings new challenges of information technology driven curriculum within the Geography subject. In turn, the interactive relationship of Geography and GIS within the current Geography curriculum is described by which the discussion of relevant GIS skills within Geography curriculum is followed. To propose the case studies that show the use of GIS for Geography education at school, Key Stages 2, 3, and 4 examples are discussed. Finally, this paper concludes with the issues that GIS benefits encourage geography teaching and learning and that potential applications can support not only the development of new teaching tools and learning strategies in geography education at schools, but also contribute to extend geographical skills and capabilities to collaborate with other subjects in school education in Korea.

BIM (Building Information Model) and GIS (Geographic Information System) are applied widely to all stages (Planning - Design - Building - Maintenance) of construction. Recently, research for designing an integrated BIM/GIS platform has been conducted to determine the synergy effects. This paper reports the derivation of BIM/GIS platform application scenarios and definition of specific functions in construction planning and design phases. First, BIM/GIS application scenarios and platform functions are derived for each phase based on an analysis of business affairs. Second, SW functions, which compose platform function, are defined. In the construction planning phase, location selection and route location business affairs were analyzed. Preliminary design and detailed design business affairs were analyzed in the construction design phase. The result of this research can be used for BIM/GIS integrated platform design in the future.

This paper describes a GIS framework for geo-semantic information retrieval in mobile computing environments. We built geographic ontologies of POI (point of interest) and weather information for use in the combination of semantic, spatial, and temporal functions in a fully integrated database. We also implemented a geo-semantic app for Android-based smartphones that can extract more appropriate POIs in terms of user contexts and geographic ontologies and can visualize the POIs using Google Maps API (application programming interface). The feasibility tests showed our geo-semantic app can provide pertinent POI information according to mobile user contexts such as location, time, schedule, and weather. We can discover a baking CVS (convenience store) in the test of bakery search and can find out a drive-in theater for a not rainy day, which are good examples of the geo-semantic query using semantic, spatial, and temporal functions. As future work, we should need ontology-based inference systems and the LOD (linked open data) of various ontologies for more advanced sharing of geographic knowledge.
