基于移动GIS的可定位媒体云平台设计与实现

Design and Implementation of a Locatable Media Cloud Platform

可定位媒体是表达、传递GIS信息的重要数据来源,现有对可定位媒体数据的采集、存储、检索的研究多局限于空间坐标信息的获取,忽视速度、方向、描述信息等相关属性的采集,缺少支持多方式检索的数据组织方案研究。本研究基于现有可定位媒体采集技术及电子地图技术,提出了现实可行的采集、存储、检索新方案,设计开发了一个集可定位媒体采集移动应用子系统和可定位媒体管理子系统于一体的综合系统———可定位媒体采集检索云平台,实现多媒体与相关信息一体化实时集成,为各类需要应用到可定位媒体相关技术的领域提供技术支撑。

Locatable media is an important data source to express and transmit GIS information.The existing researches on the acquisition,storage and retrieval of locatable media data are mostly limited to the acquisition of spatial coordinate information,ignoring the acquisition of speed,direction,description information and other related attributes,and lack of data organization scheme supporting multi-party retrieval.Based on the existing location-based media acquisition technology and electronic map technology,this paper proposes a practical and feasible new scheme of collection,storage and retrieval.It designs and develops a comprehensive system,which integrates the mobile application subsystem of locatable media collection and the positioning media management subsystem,the cloud platform of locatable media collection and retrieval,so as to realize the real-time integration of multimedia and related information,It provides technical support for all kinds of fields that need to be applied to the technology of locatable media.
