  • Since 1995, national and local governments have competitively initiated many and large GIS projects and audit for the projects becomes an important issue. So far, the audit in the Information Technology(IT) area has tried to deal with the issue but ineffectiveness has been found for the successful GIS project management. Effective auditing is a critical element for the project management. In order to establish a proper audit model for the GIS projects and to promote auditing activities in the projects, this study constructs two hypotheses and tries to prove them. The hypotheses are as follows : 1) For a good audits model for GIS, unique characteristics of a GIS project audit items and the scope of the audit need to be identified. 2) The scope of audit needs to be classified according to the requests from tasks in the projects. To prove the hypotheses, this study analyzes positive aspects of audit in IT and construction projects, clarifies the audit items in GIS projects by comparing with them, and classifies the scope of the GIS audit based on various types of GIS projects. As a results, 5 types of the GIS audit are identified : (1) audit for project management, (2) audit focused on IT, (3) audit characterized by GIS technologies, (4) GIS database audit and (5) consulting services for critical problems in the projects. In addition, 4 criteria in classifying the GIS projects are suggested for the GIS audit. The 4 criteria are domain, scope, duration, and GIS applications technologies. Especially, GIS technology considered in this study includes GIS software, methodologies for GIS development, GIS database and quality control of GIS data, which are not usually reflected in the existing studies about in GIS audit. Because the GIS audit depends on a type of GIS projects, scopes of the audit can be flexibly reconstructed in accordance with the types of GIS projects. This is a key to effective and realistic audit for the future GIS projects. Strategies for effective GIS audit are also proposed in terms of the following: GIS project management, goal establishment in each audit stage, documentation from GIS audit, timing strategies for intensive GIS audit, and designing team structure.

  • Even on the point that the 3rd National GIS project is being executed following the completion of the 1st and 2nd, the National GIS utilization is still very low. It is well reasonable to anticipate that the utilization will grow much higher, as the national spatial data infrastructure had been almost equipped through the 1st and 2nd project periods. Facing the ubiquitous era, in particular, as the national-level GIS demand is to increase to a great extent, pre-established GIS application scope will become much wider, too. In preparation for these, the current study focused on the National GIS utilization system by reviewing on the execution procedures to evaluate the outcomes. For the actual administration procedures, to note, the National GIS utilization statuses by local municipalities were investigated in depth. And the barriers for the National GIS utilization enhancement were analyzed to look for feasible solutions. The results suggested were aimed to contribute to the amendment of the 3rd Master Plan, and to be used as part of the basic data for the establishment of the 4th Master Plan for the National GIS.

  • GIS is considered as a big industry or business in the field of applied sciences. Recently GIS market in Korea is growing rapidly for LBS, Telematics, Web-geographic information services. This paper attempts to focus on the interrelationship between GIS and geography, and the question of how geography emerged out of intellectual trends within GIS to examine possible contribution of geographers in GIS fields. The application of GIS appears to be largely technical in nature. It is important for the GIS operator and the consumer of GIS products to be aware of the geographical concepts that underpin GIS operations. Also it is seen that many departments of geography in Korea have attempted to actively adopt GIS into their education program, with aim to improve the status. GIS has promoted a shift towards applied geography from academic geography. GIS researchers and educators in geography are concerned not with technology, but with the basic concepts and the issues relating to its use, in comparison with other academic fields. It is the responsibility of geography community to make sure that our students receive a geographical education that includes problem-solving, critical thinking and technical capabilities. It is concluded that promoting GIS technology in geography curriculum is essential for the further expansion of geography within GIS and also for the survival of geography.

  • OGC(Open GIS Consortium) suggests the 'OpenGIS Simple Feature Specification for CORBA' which is the OpenGIS implementation specification for CORBA to specify standard interfaces for reuse and interoperation among distributed heterogeneous GIS resources in the CORBA distributed computing environment. An OpenGIS server that supports this implementation specification moat correctly implement all interfaces defined in the OpenGIS implementation specification to be interoperable with wrapped GISs efficiently. In this paper, we have designed and implemented an OpenGIS server based an object relational GIS, called GEUS that integrates GIS and database technologies to provide spatial data types and spatial operators from the DBMS engine level. In the CORBA distributed computing environment, clients can access geospatial data stored in GIS wrapped by the OpenGIS server through the standard interfaces defined in the OpenGIS implementation specification for CORBA. In addition, clients can use geospatial operation features provided by a back-end GIS and interoperate with other GISs.

  • Despite of a huge amount of GIS data were distributed in the private sectors, they were gradually decayed due to lack of the legal preparation or civilian data distribution channels. In order to solve these problems this study was mainly focused on the civilian GIS data distribution and demonstrated a proposed direction through the requested questionnaire and analysis of the civilian enterprises and public sectors for the favorable civilian GIS distribution flow. The implementation of the civilian GIS data distribution center(provisional name) was proposed fir the civilian GIS distribution flow because of the fact that civilian sectors were seriously requested to build and to operate the civilian GIS distribution organization through the result of the requested questionnaire. The requested questionnaire items were selected as the civilian enterprises distribution, data implementation and management, low and regulations, NGIS distribution network business, and civilian GIS distribution renter build to activate and to participate civilian GIS distribution. Therefore, three implementation models and three implementation operation were proposed to guide a roll of the civilian GIS data distribution center and the distribution boundaries.

  • The Ministry of Construction and local governments have spent lots of money to construct 1: 1,000 scale digital topographic map. However the digital map is used only in facility management departments and the department in charge of GIS. In local governments, almost 70 ∼ 80 % of data are related with maps, which represents GIS technique and the digital maps could be used 70 ∼ 80 % of local government tasks. In this circumstances, it is necessary to spread out GIS usage through GIS education. However, there are lots of limits in GIS education such as number of people which can take classes at one time, physical location and size of classroom, and curriculums etc. To overcome these limits, cyber GIS education is becoming more important. This study presents how the cyber GIS education should be composed for the local government officers. For this purpose, this study accomplished followings ; grasp current GIS education status, analyze the needs of GIS education for local government officers, propose cyber GIS courses and curriculums according to the level of officers.

  • The purpose of this study is to present the role of NGIS(National Geographic Information System) and the development strategy for Business GIS in the ubiquitous society. We analyze the level of GIS technology with the ICT(Information Communication Technology) as well as GIS application trends especially in location-based circumstances. Also, we advocate not only making GIS contents to meet the international standards such as GML(Geography Markup Language) and TPEG(Transport Protocol Experts Group) but applying GIS as a killer application to oncoming diverse ICT areas including LBS(Location -Based Service), Telematics, ITS(Intelligent Transport System), gCRM(geographic Customer Relationship Management), DMB(Digital Multimedia Broadcasting), u(ubiquitous)-City and u-Town. Finally, we build a conceptual Business GIS model based on NGIS for QoS, standardization, R&D, education, and security.
