The renewal update of the digital map constructed through NGIS has been conducted for the enhancement of usage, maintenance so that the latest data is guaranteed. The total update has been done every five years for five regions of the country using aerial photographs and satellite images. By launching the third phase of NGIS, the updating plan was changed from total to total or partial update including the real time update scheme. Furthermore, the update period was improved from five to two years and four years for a large and a small city, respectively. Therefore, it is necessary to develope a matching technique which combines various geographic information (such as drawing map, surveying drawing and map) with exact position on the digital map. In this study, we developed a matching algorithm based on central point and suggested a method which uses general surveying drawing for revision/update of the digital map. The general survey is conducted when a civilian development on lands are approved. Thus, the outcome from the survey, which is the general survey drawing, contains the latest various contents such as road, building, water pipe and manhole. A consistent and efficient method using the general survey drawing for near real time update of the digital map by applying the developed matching algorithm is presented.

The convergence industry is a combination of technologies or industries of the same type or various types, thereby maintaining and/or expanding the existing values or creating fresh values. As the industry is drawing greater attention over the world, each country is making huge efforts to provide support for it. GeoSpatial Information is a representative convergence industry characterized by being utilized as a basis for other industrial fields by being linked and fused with other industries and technologies. It is well recognized as being a promising industry that will likely lead the national economy in the future. GeoSpatial Information is necessary to analyze the distinctive features and obstacle factors of the convergence industry. Because it will be able to induce a smooth convergence among different industries. In this paper, we has segmented the support elements through a comparative analysis of the legal system related to (Nano Technology, Information and Communication Technology, Culture Technology, etc)the convergence industry. Based on this proposed policy support for GeoSpatial Information Convergence industry. We expect that this study will be used as basic data of the policy established to effectively support for the GeoSpatial Information convergence industry.

With a view to creating beautiful farm villages, this study aims to exploit space syntax and thereby establish a systematic plan for refurbishing common farming facilities in farm villages by expanding a remodeling plan that has so far been focused on farm houses to cover different villages as well as in spatial scope. For this purpose, the study has extracted a system of categories for common ownership facilities in farm villages and applicable elements needed for collaboration in the space of joint production by performing a comprehensive analysis of related literature for the purpose of researching the distribution of common farming facilities. Based on such categorization of applicable elements, the study conducted a field survey of the four types of farm villages such as suburban area (Hwaseong), inland farming-centered area (Jeungpyeong), coastal & plain area (Goheung), and mid-mountain area (Gangneung), through group discussions by participating researchers and field pilot surveys. Also, space analysis has come up with measurements based on the five criteria of integration, local integration, control, connectivity, and spatial depth. And a plan for type-specific remodelling of common farming facilities has been drawn up through standardization based on the values in integration for different villages and spatial depth for common farming facilities. The significance of the current study consists in identifying how the location of common farming facilities influences the characteristics of different villages in terms of spatial structure and then drawing up guidelines for planning their placement.

There are two methods to survey the natural cave. One is plane table surveying and the other is recording chart surveying. The drawing maps drawn by these methods are 2D. Furthermore, it is difficult to figure out the accurate dimension about full sections and whole interior products because of use of plane table and recording chart. Accordingly, in this study, the 3D spatial information about Dangcheomuldonggul was constructed by the Terrestrial LiDAR and high resolution digital camera where is belong to Jeju Volcanic Island and Lava Tubes as the first World Natural Heritage of the Republic of Korea. Also, the utilization possibility of 3D spatial information was suggested to the basic data of deformation and change detection through structure analysis, section analysis, shape analysis, and interior products analysis.

This paper attempts to complement the methodological and conceptual lack of spatial thinking in Korean women's movement research and to facilitate further discussion on this field of research, by drawing on recent academic discussion on scale developed particularly among the Western critical and feminist geographers. The purposes of the paper are following. First, it addresses the need to utilize the concept of scale in women's movement research. Numerous spatial metaphors often proliferated with indiscretion in the feminist approach have rather tended to hinder fully understanding the spatiality of social movements. In order to examine the spatiality of social movements as both conceptual tool and praxis, not merely as metaphor, the paper incorporates main issues in recent scale discourses with particular attention to the debate between Marston and Brenner, and explores their implications for women's movement research in Korea. Second, it emphasizes the multi-scalar approach by highlighting the role of micro-scale, the less studied side in social movement literature. The public and the private divide, the long time battle ground in feminist research, is often intermingled with the hierarchical scalar understanding which considers the global as more powerful and important than the local. The reproductive realm, however, is indispensably related to production and political economic realm. The paper explores the very site where both the public/private divide and the hierarchical scalar understanding can be dismantled. It is the site where the private becomes public and the local becomes the global (and vice versa). Drawing on a brief example of an anti-FTA movement of women with strollers in Korea, it examines the way the multi-scalar approach advances the understanding of Korean women's movement.

This study aims to develop a standard protocol by which users can exchange data information efficiently between KOSDIC and GIS. The ultimate goal from this study is to propose a data exchange format using KOSIC. The background of this study is that GIS industry sector is vigorously developing linked to spatial information construction such as UIS, LIS, EIS, AM/FM through supporting by regional government institution. According to do, the format of data transformation becomes major issue. GIS data can easily transfer to CAD version but when CAD data convert to GIS format (DWG->DXF->SHP) cannot get high success rate due to errors and problems. In addition, CAD data feature is made from oriental structure which is made of point and line faeture so that GIS system is impossible to data transformation. In the reason, the biggest problem is discordance of symbolization in integration and standard of data format. By investigation the usability of this study, conclusion are drawn efficient alternative plan in data transformation. Though this wort we will be able to provide a better transformation of data conversion between CAD format and GIS format. Accordingly, it is of important to enrich the integrated construction information infrastructure, which accommodates ever-changing constructions environment.

As human beings spend more time indoors, and with the growing complexity of indoor spaces, more focus is given to indoor spatial applications and services. 3D topological networks are used for various spatial applications that involve navigation indoors such as emergency evacuation, indoor positioning, and visualization. Manually generating indoor network data is impractical and prone to errors, yet current methods in automation need expensive sensors or datasets that are difficult and expensive to obtain and process. In this research, a methodology for semi-automatically generating a 3D indoor topological model based on IndoorGML (Indoor Geographic Markup Language) is proposed. The concept of Shooting Point is defined to accommodate the usage of omnidirectional images in generating IndoorGML data. Omnidirectional images were captured at selected Shooting Points in the building using a fisheye camera lens and rotator and indoor spaces are then identified using image processing implemented in Python. Relative positions of spaces obtained from CAD (Computer-Assisted Drawing) were used to generate 3D node-relation graphs representing adjacency, connectivity, and accessibility in the study area. Subspacing is performed to more accurately depict large indoor spaces and actual pedestrian movement. Since the images provide very realistic visualization, the topological relationships were used to link them to produce an indoor virtual tour.
