지리정보의 중요성이 널리 인식되고 사회 각 분야에서 지리정보에 대한 수요가 날로 증가되고 다양해지고 있지만 GIS의 개발, 설치, 유지, 보수의 어려움에 따른 고가의 비용과 시장에 대한 적응력부족으로 GIS의 광범위한 활용이 저해 받고 있는 실정이다. 또한, 개인을 위한 GIS 서비스나 응용프로그램의 하나의 기능 컴포넌트로서의 GIS 서비스가 GIS의 주류로 발전할 것으로 예측되고 있지만 이를 지원하기 위한 GIS 개발, 배포 모델과 기반기술이 결여되어 있다. 그러나, 사용자가 월 정액요금을 지불하고 인터넷 또는 인트라넷을 통하여 ASP (Application Service Provider)에 의해 원격 중앙 서버에 설치, 관리되고 있는 소프트웨어 응용프로그램을 사용하는 형식은 혁신적인 소프트웨어 개발과 배포 모델로서 차세대 컴퓨터 환경의 기초로 각광 받고 있으며 이를 GIS에 적용할 때 GIS의 광범위한 응용과 원활한 유통을 크게 추진할 것으로 기대된다. 그러므로, 현시점에서 GIS ASP를 위한 합리적인 모델과 이에 근거한 소프트웨어 플랫폼에 대한 연구와 개발이 절실히 필요하다. 본 논문에서는 ASP 환경 하에서 더욱 신속하고 편리한 GIS 개발, 통합, 배포를 가능하게 하고 보다 나은 질의 GIS ASP 서비스를 제공하기 위하여 마이크로소프트의 ASP 플랫폼인 .NET 기반의 3 계층 GIS ASP 모델을 중심으로 하는 GIS ASP 소프트웨어 플랫폼의 설계를 제시하였다.

These days open source softwares are being introduced and applied in many countries in the world. Especially, both government and private companies tend to become an spearhead in vitalizing the open source software. In this paper we try to check the degree of vitalizations in open source GIS software and to draw implications in vitalizing ecosystem of open source GIS software. Key players of open source GIS software ecosystem are government, private companies, academic and research institutes, and nonprofit foundations. Government does not have very little policies related to the investment and the support of open source GIS software. Private companies related to the open source GIS software are very few in the number and do not have any clear business model to make a profit. Academic and research institutes are weak in using the open source GIS software, which can be an major obstacle to cultivate software developers. OSGeo Korean branch, established in 2009, is the only nonprofit foundation in Korea which makes an effort to vitalize the open source GIS software, but its results are not very strong up to now in view of both quality and invigoration. In order to vitalize the open source GIS software ecosystem, lots of efforts of key players are needed. Especially, government efforts are very important because it can provide a trigger in vitalizing the open source GIS software ecosystem. The tasks that government should propel are R&D investment, test bed projects in the area of public sector, professional manpower training, and international cooperation and marketing.

Recently, the open source software market is becoming bigger and bigger as its demand keeps increasing worldwide. A variety of policies have been driven in Korea in order to vitalize the open source software. However, the performance for vitalizing the open source GIS software has not been initiated yet. The purpose of this research is to generate the support plan to vitalize the domestic open source GIS software which is appropriate for real field by analyzing the actual demand and user requirements. For this purpose we reviewed all the researches related to the vitalization of the open source software and conducted a survey based on the awareness of the open source GIS software, the current vitalization status, the adoption intent and necessary strategies for vitalization. According to the survey, the intent of adopting the open source GIS software is relatively high in both enterprises(97%) and universities(89%). On the other hand it is very low in public organizations(69%). As a result, the survey implies that more intense public relations are needed to escalate the awareness of the open source GIS software in the public organizations. In addition, the survey shows that both education and technology support are definitely needed as a strategies for the vitalization of the open source GIS software. We expect that this research can be utilized as a basic material for the policy making of the vitalization of the open source GIS software in Korea in the future.

The 'Open Source' of programing is a method that is not only sharing the source, but also making the S/W by the low cost and easy way. In this study, we made the urban facilities management system(FMS) based on the GeoFOSS of Open Source. This system has the GIS function of the urban facilities management, the u-GIS function using the USN for processing the spatial information. Also, as we use the GeoFOSS of 'Open Source', we can have received many benefits. First, this system has the economic impact, because it is not necessary to buy the commercial GIS software. Second, this system can make most functions of the GIS, the performance does not bad compared to other products. Also, this system strictly conforms to the international standards, it is easy to get a repair, maintenance and interoperability.

The Information Technology has progressed to the open architecture, component, and multimedia services under Internet, ensuring interoperability, reusability, and realtime. The GIS is a system processing geo-spatial information such as natural resources, buildings, roads, and many kinds of facilities in the earth. The spatial information featured by complexity and diversity requires interoperability and reusability of pre-built databases under open architecture. This paper is for the development of component based open GIS Software. The goal of the open GIS component software is a middleware of GIS combining technology of open architecture and component ensuring interoperability of spatial information and reusability of elementary pieces of GIS software. The open GIS component conforms to the distributed open architecture for spatial information proposed by OGC (Open GIS Consortium). The system consists of data provider components, kernel (MapBase) components, clearinghouse components and five kinds of GIS application of local governments. The data provider component places a unique OLE DB interface to connect and access diverse data sources independent of their formats and locations. The MapBase component supports core and common technology of GIS feasible for various applications. The clearinghouse component provides functionality about discovery and access of spatial information under Internet. The system is implemented using ATL/COM and Visual C++ under MicroSoft's Windows environment and consisted of more than 20 components. As we made case study for KSDI (Korea Spatial Data Infrastructure) sharing spatial information between local governments, the advantage of component based open GIS software was proved. Now, we are undertaking another case study for sharing seven kinds of underground facilities using the open GIS component software.

The purpose of this study is to propose an open source GIS software business model for the revitalization of Korean open source GIS software industry. In this study, we categorized the types of open source software business models and developed an open source software business strategy suitable for GIS companies in Korea. To propose a business model, we applied the business model canvas which is often used in the area of business studies to analyze new business models. We tried to develop the open source GIS business model through both interviews and case studies with Korean open source GIS software companies. We propose three different types of open source GIS software business models such as distributor model, producer model, and 3rd party service provider model as follows: first, the companies which belong to distributor model can carry out business by providing professional services in the market of open source software. Second, the companies which belong to producer model can sell their products to the global market as well as the domestic market. Lastly, given the growing interest in domestic open source software, the number of third-party service providers is likely to continue to increase in the future. Therefore, it is expected that the companies which belong to the third party service provider model will be able to develop various business models by securing the technology.
