In any production and construction of geospatial information covering surveying, survey control point is a vital geospatial information. Survey control points in South Korea are currently classified as following: national control points, public control points, and cadastral control points. Each of these different categories of survey control points act as a basis and sets perimeters for the production, management and operation of subjects within the category. Universal standard, the unified format between different survey control points, also, are not yet defined, causing difference in basic information provided by altering categories and disturbance in connecting, managing, utilizing and operating survey control points. Establishment of a standard regarding survey control points, is therefore required for the efficacy of their utilization. This study, to solve such inadequacies, selects management items for creation of standardized survey control point, by investigating domestically and internationally the status of operating survey control points, determining data model for management, establishing TTA and agency standards, and establishing of activation methodology for survey control point standards.

To make use of surveying data obtained from different sensors and different techniques, it is a pre-requite step that register them in a common coordinate system. For this purpose, we developed methodologies to register IKONOS-2 Satellite Imagery using LiDAR(Light Detection And Ranging) data. To achieve this, conjugate features from these data should be extracted in advance. In this study, linear features are chosen as conjugate features. Then, to register them, observation equations are established from similarity measurements of the extracted features and the results was evaluated statistically. The results clearly demonstrate that the proposed algorithms are appropriate to register these data.

Recently, as GIS industry has substantially grown up, convergence between industries such as the application coverage of surveying and cadastral information is gradually on the increase. The new approach of convergence between topographic surveying and cadastral survey is indispensable to make the change of geospatial environment ready and to maximize the utilization of National Spatial Data Infrastructure(NSDI). The purpose of this paper is to seek the way of synergistic improvement in topographic surveying and cadastral survey in comprehensive aspects of national geospatial information. First, we reviewed policy environment to clearly establish aim of convergence and promising perspective of GIS industry policy, considering NSDI. In addition, we examined current state of administration (organization, human resource, service) and institution situation. We came up with interior ability and external policy environment as well as critical success factor for the synergistic convergence by using SWOT analysis. Lastly, we developed basic perspective of convergence and improvement model and concrete scheme for stakeholder to complementary make progress. We can come to conclusion that the convergence of topographic surveying and cadastral survey should be not only carried in macro outline of successful NSDI but also committed to completion and maintenance of GIS framework.

In the 21th century as knowledge-based society and according as GIS is embossed, demand of map is increasing rapidly for GIS's basic. Ministry of Construction & Transportation Republic of Korea National Geographic Information Institute who supervise basis geography information run the studies of basis geography information construction, therefore choice of each subject extent and standardization of data model for basis geography information is attained. In this study, framework data has been established in three steps according to Framework data Product Specification in Facility Area. Also the evaluation of usability was implemented as combining Framework data.

In this study, sample area was selected to compare the conventional method with photogrammetic method in basic planning of country club. Also various elements of planning, such as vegetation and water system, were considered through interpretation of aerial photographs and topographic maps, vegetation maps and water system maps were made as well as digital terrain models. These were used to analyse tophographic changes and landscape. As a result of comparing with the conventional method, it was shown that photographic interpretation could give more detail values than the conventional method, and that the digital terrain model could predict changes of topography, landscape and water system with more asccuracy. Consequently, the method of digital terrain model and photographic interpretation proved to be more effective than the conventional method in the case of water treatment, and planning of landscape and land utility.

스트립 방식으로 촬영된 위성영상의 기하학적 모델링시에는 일반적으로 단위모델별로 위성영상에서 식별이 용이한 지점을 지상기준점으로 선정하여 영상에서의 좌표를 해석도화기나 컴퓨터 화면상에서 획득하고, 그에 대응하는 지상좌표는 현지측량이나 기본지도로부터 얻는다. 현지측량방법의 경우에는 정확하고 신뢰성있는 좌표를 제공해 줄 수 있는 반면에 현지로의 접근이 용이해야 하고 비용과 시간이 많이 소요되며, 소축척의 기본지도상에서 직접 독취하는 경우에는 지도자체에 내재된 오차의 정도가 불명확하고 지상기준점으로 선정한 지점이 명확히 표기되어 있지 않은 경우가 있으므로 영상좌표 측정시에 오차의 유발 가능성이 크다. 특히 영상 해상도 $5{\sim}10m$의 연속된 화상을 3차원 기하학적 모델링을 수행하기 위하여 현지측량에 의해 지상기준점을 획득하는 방법은 경제성 및 효율성 측면에서 불리하다. 따라서 본 연구에서는 삼각점 조서를 이용하여 연속촬영된 SPOT 위성영상을 스트립 단위로 모델링하여 영상해상도 수준의 위치정확도를 얻을 수 있는 연속화상 모델링기법을 제시하였다.
