  • The OGC(OpenGIS Consortium), which is standardization organization of geographic data, have been studied standard for geographic data such as GML and GML based annotation for image and map. Annotation for map is applicable in various ways, understanding about geographic data, decision making and exchange of communication. For instance, Map annotation can be used for highlighting tour-course as symbols or explaining it as text on a map in tourism. This study suggests some annotation methodology for national digital map and presents a simple implementation of it. Firstly, this study suggests a way of updating OGC annotation schema which corresponds with DXF format and creating a GML application schema using the updated OGC annotation schema. Also it suggest a way of converting instance documents of annotated map to VML document with XSLT and VML for display. Later, it is needed to study for supporting another formats as well as DXF format. In addition, it is needed to study for managing the history of updated map entity with annotation in Local governments UIS(Urban Information System) in practical aspects.

  • This paper suggests design and implementation of moving objects management system using GML which is the XML encoding standard of geographic data. The proposed system integrates spatial data and moving objects data, utilizing the concept of Web Feature Services. While integrating data, standard data model and interfaces, proposed by OGC, are used. Since GML is standard for storing and transferring spatial/non-spatial data, interoperability and extendibility can be obtained. In addition, we propose efficient developing environment for the moving object management system by providing components having Web/Mobile interface. If the proposed component be development methods are used, it is easy to add or modifyservices in the mobile system and pla

  • Recently, because of the extensive use of geographic information in the various fields, the requirement for the easy circulation and utilization of the various geographic information among the individuals, organizations, societies and countries is raised. In order to support the interoperability of the heterogeneous geographic information in the various fields, OGC(Open GIS Consortium) proposed the GML(Geography Markup Language) specification that defines the XML encoding rule about the heterogeneous geographic information. In addition, ISO/TC 211 adopted the GML specification to make it as the international standard. Therefore, in this paper we first analyzed the GML 3.0 specification in detail that can support the interoperability of the heterogeneous geographic information. And then we suggested and applied the mapping rule that define the encoding method to improve the encoding process easily and efficiently. Finally we designed and implemented the GML 3.0 encoding system using the mapping rule to encode the geographic information that was constructed in spatial databases into the GML 3.0 document. Especially, we used ZEUS as a spatial database system to test our encoding system in this paper.

  • OGC(Open GIS Consortium, Inc.)에서 2000년에 XML의 지리정보 처리를 위한 GML 1.0이 제안된 이후 최근 GML 3.0이 발표되기까지 국제적으로는 다양한 GIS 응용분야에서 GML을 현실 문제에 이용하고자 하는 시도가 이루어지고 있다. 현재 우리나라에서도 국가 GIS(NGIS)에서 GML을 도입하여 국내 표준안으로 추진하고자 다양한 기반연구가 진행되고 있다. 본 연구는 중요한 GIS 응용중의 하나인 지질자원 정보 분야에서 GML을 활용하기 위한 기반연구로서 우리나라의 표준 지질도(또는 수치지질정보)와 기타 지질자원 정보 인프라 구축에 적용될 수 있는 다양한 지구과학자료를 대상으로 하였다. 따라서 본 연구에서는 지질자원 분야에서의 GML 응용을 위한 기반 데이터 모델과 이를 처리하기 위한 아키텍처를 UML 기법으로 설명하고, 이를 바탕으로 시험 구현된 운용환경에서 실제 대상 지역을 선정하여, 연구지역에 대한 지질자원 정보의 GML 적용 사례를 제시하고자 한다. 이를 위한 연구 내용으로는 수치 지질도를 XML-GML의 기본 스키마구조에 따라 엔코딩한 뒤, 주제정보의 표현을 위한 XSLT, SVG 파일 변환 처리 등을 수행하였다. 결론적으로 본 연구는 지질자원 분야의 정보화 인프라 구축을 목적으로 하는 기초 시험연구로 수행되었는 바, 우리나라에서는 2001년 이후 GIS 수치 주제도로서 수치 지질도의 보급이 활성화되면서, 이 정보를 제작/공급하는 기관이나 업무에 사용하는 기관 등에서 GML 기반으로 데이터를 제작하거나 운용이 가능할 것으로 생각된다. 또한, 다른 분야에서 GIS 주제정보를 다루는 경우에도 GML을 주제정보와 연계하여 현실 문제에 적용이 가능한 창조 모델로 이용될 수 있을 것으로 생각된다.}94,\;29.4{\pm}30.3,\;45.1{\pm}44$로 Mel 10군과 Mel 30군이 유의적인 감소를 보였으나(p<0.05) 이들 두 군 간의 차이는 나타나지 않았다. 이상의 결과로, 랫트에서 복강수술 후 melatonin 10mg/kg투여가 복강 내 유착 방지에 효과적이라고 생각된다.-1}{\cdot}yr^{-1}$로서 두 생태계에 축적되었다.여한 3,5,7군에서 PUFA 함량이 증가한 반면, SFA 함량은 감소하여 P/S 비율, n-3P/n-6P 비율은 증가하는 경향이었으며 이는 간장의 인지질, 콜레스테롤 에스테르, 총 지질의 지방산조성에서도 같은 경향을 볼 수 있었다.X>$(C_{18:2})$와 n-3계 linolenic acid$(C_{18:3})$가 대부분을 차지하였다. 야생 돌복숭아 과육 중의 지방산 조성은 포화지방산이 16.74%, 단불포화지방산 17.51% 및 다불포화지방산이 65.73%의 함유 비율을 보였는데, 이 중 다불포화지방산인 n-6계 linoleic acid$(C_{18:2})$와 n-3계 linolenic acid$(C_{18:3})$가 지질 구성 총 지방산의 대부분을 차지하는 함유 비율을 나타내었다.했다. 하강하는 약 4일간의 기상변화가 자발성 기흉 발생에 영향을 미친다고 추론할 수 있었다. 향후 본 연구에서 추론된 기상변화와 기흉 발생과의 인과관계를 확인하고 좀 더 구체화하기 위한 연구가 필요할 것이다.게 이루어질 수 있을 것으로 기대된다.는 초과수익률이 상승하지만, 이후로는 감소하므로, 반전거래전략을 활용하는 경우 주식투자기간은 24개월이하의 중단기가 적합함을 발견하였다. 이상의 행태적 측면과 투자성과측면의 실

  • A systematically structured 3D information model can be effectively utilized in many application fields. This study presents the methodology of generation and application of the city information model, which is suited for the management of the flood damage information. To ensure the interoperability and re-usability of the information, this study develops application methodology to utilize the information attributes included in the CityGML as an open standard data schema and extension methodology for additional information attributes. Also, an effective combining method for topography and building model was proposed. Using the data extracted from the combined information model based on a real flood damage case, it was shown that the numbers of casualties and isolation during a flood can be predicted and as a result, the applicability of the data model on flood damage estimation is naturally verified.

  • Recently indoor navigation with indoor map such as Indoor Google Maps is served. For the services, constructing indoor data are required. CityGML and IFC are widely used as standards for representing indoor data. The data models contains spatial information for the indoor visualization and analysis, but indoor navigation requires semantic and topological information like graph as well as geometry. For this reason, IndoorGML, which is a GML3 application schema and data model for representation, storage and exchange of indoor geoinformation, is under standardization of OGC. IndoorGML can directly describe geometric property and refer elements in external documents. Because a lot of data in CityGML or IFC have been constructed, a huge amount of construction time and cost for IndoorGML data will be reduced if CityGML can help generate data in IndoorGML. Thus, this paper suggest practical use of CityGML including deriving from and link to CityGML. We analyze relationships between IndoorGML and CityGML. In this paper, issues and solutions for linkage of IndoorGML and CityGML are addressed.

  • Most 3D models found in the literature focus on theoretical topology for exterior 3D volumes. Although there are a few indoor models such as CityGML or IFC, implementing a full topology for the indoor spaces is either less practical due to the complexity or not even necessary in some application domains. Moreover, current spatial DBMSs do not support functionalities explicitly for 3D topological relations. In this study, an alternative method to build a 3D indoor model with less complexity ernativespatial DBMS is suggested. Focusnation the fact that semantic attributes can be storedion the floor surface, we suggestivemulti-layered 3D model for indoor spaces. We show the process to build the proposed model in the PostGIS, a spatial DBMS. And, then, as an example application, we illustrate the process to build and run a campus building information system.
