Web3D 환경에서의 GML기반 교통데이터 모델과 위성영상정보 연계 활용 지형 공간 시스템 설계 및 구현

Abstract

Standardization or standard-r디ated study are regarded as main issues in GIS application. Though several GIS standards and specifications have been released, there are a few actual application cases adapting those. In this study, we designed and implemented a geo-spatial information processing system with editing, storing, and disseminating functions, in which standard GIS transportation data model by TTA linked with OGC-GML, XML-based geographic features encoding standard. The system developed in this study enables us to transfer and edit transportation entities based on TTA standards to GML, importing ESRI shape file. In web-based system, GML-based databases are transformed to SVG and X3D 61e, for the purpose of web publishing. TTA GIS tranportation data model is used in this study, and tested, however, standard data models from other application fields also can be easily applied because this system basically provides data importing and editing functions. This system as practical tools can be utilized for applicability test of GIS standard data model and practical operation of standard specification.
