摘　　要：在应急快速反应场合,现场空间位置信息、动态影像信息的实时采集、高效处理和便捷提供,已经成为地理空间信息服务的基本要求。以旋翼无人机(VTUAV)为平台的集成传感器实时探测、车载移动集群式高速处理和宽带无线网络信息发布为技术途径,本文构思一种地理空间信息直播服务(LGI)的样式和技术体系,结合典型应用的实际需求,具体分析了技术实现的环节、要点及未来推进服务需要突破的主要关键技术。Real time collection of live imagery and location has constituted one of the basic requirements of geospatial information service in case of emergence fast response,along with high performance processing and quick release of data.This paper focuses on the conception and architecture of live-service for geospatial information（LGI）,its major technical routines are based on real time collection with integrated sensors in VTUAV platform and high speed processing with vehicular borne cluster system and information release with wide-band wireless networks.The link and elements of LGI and applied key technologies in the future are outlined with some typical application instances.
