Abstract

We present a data model for GeoVideo and a system framework for VideoGIS,including the data structure of GeoVideo data,the processing flow of Geovideo data,key modules of a VideoGIS,and the technical design and implementation issues.Several key technologies,such as Web map design,GeoVideo management,GeoVideo player design and system integration,are discussed in detail.Utilizing Google Maps API,ArcGIS 9.3 map services and Flash video standard,a prototype of VideoGIS is implemented.This VideoGIS provides flexible interfaces for GeoVideo query,index,visualization,navigation in the context of Web maps,and has verified the feasibility of the GeoVideo data model and VideoGIS design.
