In general, Digital Photogrammetry is based on independent workstation system, which is costly and has complex process. In this research, a new approach method regarding Digital Photogrammetry procedure is suggested using Web Processing Service, which is a GIS standard proposed by Open Geospatial Consortium. For the experiment, many Generic Processes were defined through WPS profiling procedure which defines standard unit for Photogrammetry, and with the defined process each server and client S/W module was implemented based on WPS standards. In this paper, many users can be expected to share and reuse unit process in WPS server through the web.

As the urban scale changes and the living space changes in three dimensions, the Ministry of Land, Infrastructure and Transport continuously builds various and high quality spatial information such as three-dimensional spatial information, indoor spatial information, underground spatial information and precision road map. However, although various disasters and safety accidents are rapidly increasing due to the enlargement and complexity of cities, safety management using spatial information is relatively insufficient. In this paper, we propose a data model for comparing and analyzing typical domestic and international spatial information construction cases and providing disaster safety services based on spatial information standards.

One of the biggest problems found from the results of the various GIS-related projects is this. In spite of the fact that there is a national standards on GIS data structures, in building and managing the information on a variety of facilities in an area, each of the concerned organizations has been building the information using their own standards on the selection and organizations of the target facilities, naming convention, and coding regulations of the selected facilities. This distinctively exposes the limits and problems of the national GIS data standards in adopting to the regional GIS projects, resulting in considerable problems in sharing the information already built. The national GIS data standards, therefore, should be expanded and revised. As an effort to solve the above-mentioned problems, this paper suggests an idea on the revision and expansion of the national GIS data standards in the field of road and related facilities. It is believed that same efforts should be made for the other areas of the national GIS data standards to increase the applicability to various GIS projects.

In recent years, the attention on the applications of the national or international standards to water-related information technology in practice has more increased. In particular, as the demand on spatial information technology including content development, receiving, disposal and distribution has increased, the importance of standardization has been also emphasized. However, compared with attention and demand on standardization in spatial information technology, studies on development and application of standardization are still at the initial stage. Accordingly, this study attempted to investigate the trends of international standards developed and established by International Organization for Standardization(ISO) and Open Geospatial Consortium(OGC), and to derive the adaptable integrated management standard technology for water hazard information platform. For this, we investigated big data, NoSQL, and cloud technology for the observed data provision. Furthermore, OGC WxS standard technologies for spatial information web service and ISO standards for spatial information format were investigated. Based on these investigations, we examined the strategies and plans to apply and establish the standardization for information provision.

USN(Ubiquitous Sensor Network) is a core infrastructure that makes come true the u-life in the ubiquitous society through various services of area such as u-city and u-Health. Therefore, we need to reseach about the domestic standards to establish the core technique of USN. Currently, the status of USN standards is most of technical standard and reseach that are technology for sensor node implementation and a protocol for energy-efficient communication and interlock with existing network. But, Standard and reseach for sensor network, integration management of heterogeneous sensor networks for USN application, sensing data management and USN database structure definition such as application and middleware are weak level. In this paper, we researched for standard development of the domestic sensor network service and relevant standard analysis to configure SWE(Sensor Web Enablement) of OGC(Open Geospatial Consortium) for standarded plattform technoloy in part of the middleware. Also we researched that it's a connection between domestic TTA (Telecommunications Technology Association) standards and SWE Standard. Finally, we researched for standard service plattform architecture on sensor network through analysis on the possibility of applying OGC-based services platform.

Geo-based application services linked with the Open Geospatial Consortium (OGC) Web Processing Service (WPS) protocol have been regarded as an important standardized framework for of digital earth building in the web environments. The WPS protocol provides interface standards for analysis functionalities within geo-spatial processing in web-based service systems. Despite its significance, there is few performance tests of WPS applications. The main motivation in this study is to perform the comparative performance test on WPS standards. Test system, which was composed of WPS servers, WPS framework, data management module, geo-based data processing module and client-sided system, was implemented by fully open source stack. In this system, two kinds of geo-based image processing functions such as cloud detection and gradient magnitude computation were applied. The performance test of different server environments of non-WPS, synchronous WPS 1.0 and asynchronous WPS 2.0 was carried out using 100 threads and 400 threads corresponds client users on a web-based application service. As the result, at 100 threads, performance of three environments was within an adjacent range in the average response time to complete the processing of each thread. At 400 threads, the application case of WPS 2.0 showed the distinguished characteristics for higher performance in the response time than the small threads cases. It is thought that WPS 2.0 contributes to settlement of without performance problems such as time delay or thread accumulation.

The Korean government strives to transform the society from one that stresses academic and qualification to one that stresses individual competencies. National Competency Standards(NCS) has been adopted to this end. However, NCS classifies cadastre into a group with survey and spatial information collection. Such classification limits cadastre to encompass cadastral administration, cadastral survey, geospatial survey, etc. This study reviews current status and implications of NCS, and proposes few solutions: improvement of classification system, introduction of cadastral industry cooperation model, curriculum development based on competency level, unification between NCS developer and learning module writing group, etc.

USN(Ubiquitous Sensor Network) environment that provides the service measured from sensors in real-time the information is delivered to application service. However, domestic service, application service provider environment between providers and users, most of the research are on the service platform architecture, and process the information detected by sensors between the providers of standard services platform architecture, which is a very weak level. In this paper, we proposed new service architecture though analysis of the OGC SWE(Sensor Web Enablement) with standards and research analysis of domestic standards. And we designed and implemented to each component of provider side.

The computerization project for underground facilities in Korea began in earnest after the city gas explosion in Seoul in 1994, and the Daegu subway explosion in 1995. As such a large-scale gas explosion accident caused enormous economic loss including human casualties and potential benefits, the need for computerized for efficient management of underground facilities was greatly emphasized in society. Meantime, computerization of underground facilities has been carried out according to the basic plan for building national geographic information system. In this study, problems were identified based on the current status of construction and management of underground facility information, as well as laws and regulations, and directions for establishing quality standards were presented. In addition, construction work standards such as 「Public Survey Work Regulations」, design standards, standard specifications, and technical specifications, gas technology standards, design standards, and communication works so that underground facility information can be linked and utilized in construction work by examining the linkage of the underground facilities, the targets that can be used for quality level information on underground facilities were derived, and a proposal to revise the construction standards was presented. In the future, if the quality standards are established, it is expected that the accuracy and utilization in the construction field will be increased.
