국제수로기구는 수로정보의 활용과 상호 운용성 증진을 위해 S-100 표준을 개발하여 수로분야 제품표준 개발을 위한 프레임워크로 지정하였다. S-100 표준은 S-57 표준을 대체하는 것으로서, 전자해도 간행업무와 ECDIS 개발에 직접적으로 영향을 미치는 중요한 표준이라 할 수 있다. S-100 도입에 따른 산업계 핵심기술 개발차원에서 "국제 해양 GIS 표준기술기반 차세대 항행정보지원 시스템 개발과제"가 추진되었으며, 그 일환으로 차세대 ECDIS 개발에 요구되는 S-10X 시험데이터 연구를 수행하고 있다. 본 논문에서는 e-Navigation 테스트 베드, e-Navigation MSP(Maritime Service Portfolio), 국제수로기구 S-100 기반 제품 표준 사례, 국제수로기구의 S-100/S-101 테스트 베드 현황 등의 차세대 ECDIS 시험데이터 사례 분석을 통해 차세대 ECDIS 시험데이터 구축 범위를 식별하였다. 또한 그 동안 수행한 차세대 전자해도 데이터베이스 준비를 위한 기초기술 개발 내역을 소개하고자 한다.

Geostationary Ocean Color Imager(GOCI), the World's first spaceborne ocean color observation satellite operated in geostationary orbit, was successfully launched on May 2010. The main missions of GOCI is the coastal environment monitoring of GOCI in order to meet the necessity of long-term climate change monitoring and research. The GOCI have higher spatial resolution than MODIS, $500m{\times}500m$, and 8 spectral ocean color channels. GOCI have a capability for observation on the coastal environment change, GOCI perform the observation with 8 times a day. In this paper, we presented the more improved results for observation on the coastal environment change than MODIS ocean color sensor and detected the spatial difference of CDOM for monitoring coastal environment change.

유비쿼터스 도시의 개념이 등장하면서 도시관리에 대한 중요성이 점차 부각되어가고 있다. 특히 지하시설물에 대한 안전한 관리는 안전한 도시를 표방하는 유시티 에서는 없어서는 안될 중요한 공공서비스라 할 수 있다. 최근 이러한 도시의 지하시설물의 안전한 관리를 위한 체계적인 관리 방안에 대한 연구가 국토해양부를 중심으로 활발히 이루어지고 있다. 지하시설물의 특성상 안전하고 체계적인 관리를 위해서는 무엇보다 지하시설물에 대한 정확한 위치좌표를 알아야 하고 지하시설물에 일어나는 변화에 대한 정보를 수집하기 위해 센서적용기술을 필요로 한다. 본 논문에서는 유비쿼터스 도시 내 지하시설물 구축과정에서의 절대위치확보 방안과 각 지하매설물별 특성을 고려한 센서적용방안에 대한 내용을 기술하였다.

The outbreaks of red tide were sporadic in the South Sea until 1994, but have become frequent and widespread in whole coastal waters of the South Sea and East Sea since 1995 For monitoring of red tide, many kinds of techniques such as remote sensing, GIS and fuzzy model system have been developed and applied. The purpose of this paper is to develop red tide monitoring system for collection of red tide data and biological-oceanography parameters using wireless sensor network. The wireless sensor network has been noticed as a core technology in order to realize ubiquitous computing. In this paper, we design red tide database using wireless sensor network and suggest red tide monitoring software and web-service for user and biological-oceanographer.

This study is about the development of measurement system using ubiquitous wireless communication for river flow monitoring. The system can acquire water depth, quality (temperature, pH, conductivity, turbidity etc.) while a GPS module for getting the location data of measurement points. Also this system is able to acquire the field data via RF connection and can be controlled same time. The acquired data is transmitted to a gateway system from the remote buoy using Zigbee wireless connection. And the gateway system is able to monitor the data through GIS monitoring tool. Finally the data are transmitted to a server computer using CDMA wireless connection by gateway system. The D/B of server computer are constructed automatically and monitored the project web site. The resulting system can be used for scour monitoring, environment monitoring and the other monitoring purposes such as a river flow monitoring system.

IHO has established S-100 Standard profiled from ISO 19100 GIS standards for standardization and improvement of hydrographic data and are developing S-10X Standards. IMO is implementing the e-Navigation strategy for maritime safety and marine environment protection and has established the CMDS as information standard framework which will be developed from the S-100 standard. The development domain of e-Navigation can be divided into onboard, communication network, onshore and VTS is a core actor in onshore system. In this study, we analyzed the effects of S-100 standard development on VTS through e-Navigation strategy of IMO and suggested the cooperation between hydrographic fields and VTS fields under e-Navigation strategy.

IMO adopt the revision of SOLAS convention on requirement systems for ECDIS and considered an ECDIS as the major system for E-Navigation strategy on marine transportation safety and environment protection. ENC(Electronic Navigational Chart) as the base map of ECDIS is considered as a principal information infrastructure that is essential for navigation tasks. Because ENCs are not easy to utilize for being encoded according to ISO/IEC 8211 file format, used for navigational purpose mainly, it's required to utilize in parts of Marine GIS and various marine application. In this paper, we developed KML conversion technology for ENC application. In details, we analyzed data model and encoding method of ENC, schema structure and data file of KML. Based on this results, we developed the program of KML conversion of ENCs.

Red tide(harmful algae) in the Korean Coastal Waters has a given a great damage to the fishery every you. However, the aim of our study understands the influence of meteorological factors (air and water temperature, precipitation, sunshine, solar radiation, winds) relating to the mechanism of red tide occurrence and monitors red tide by satellite remote sensing, and analyzes the potential area for red tide occurrence by GIS. The meteorological factors have directly influenced on red tide formation. Thus, We want to predict and apply to red tide formation from statistical analyses on the relationships between red tide formation and meteorological factors. In future, it should be realized the near real time monitoring for red tide by the development of remote sensing technique and the construction of integrated model by the red tide information management system (the data base of red tide - meteorological informations). Finally our purpose is support to the prediction information for the possible red tide occurrence by coastal meteorological information and contribute to reduce the red tide disaster by the prediction technique for red tide.

This study investigates how Korean Land Spatialization Group (KLSG) has controlled and managed its own R&D effectively and what particular elements have made it practical. Korean Land Spatialization Program (KLSP) has produced large amounts of practical outcomes for the intelligent land by collaborative 5 core research projects. The well-harmonized cooperations between proving ground, practical business model, and services oriented integration and others have driven the KLSG to an succeedable management. The active role for practicality is prominent with its usefulness and competitiveness. KLSP is financially and administratively supported from Ministry of Land Transport and Maritime Affairs of Korea (MLTM). By investigating relationships between 5 core research projects involved in the R&D projects of KLSG, it has been found out that R&D projects of KLSG bring forth practicality and commercialization. The results of this study presents strategies of KLSP in conducting research for practicality and commercialization of GIS technology and integrated geospatial information.
