摘要
讨论了面向第三代Internet和Web2.0模式下的空间信息服务需求,提出了空间信息服务的数字地球影像体系,并给出了一种可量测实景影像数据获取、组织管理以及与4D产品集成的技术途径。首次提出了可量测实景影像空间信息服务体系,对基于可量测实景影像的空间信息服务的前景进行了展望。
Firstly, the requirements of geo-spatial information are described facing to the next generation of Internet and Web 2.0. A digital Earth imaging system for geo-spatial information services is proposed to set up. A new concept of digital measurable images （DMI） is proposed. The related technique for data acquisition, organization and management for DMI as well as its integration with existing 4D products （DEM/DOM/DLG/DRG） are described. Based on these techniques a new geo-spatial information service system. DMI based vLBS is set up to improve the quality of LBS with visible, measurable and minable stereo images. Finally, the appliatability of DMI based vLBS is briefly discussed.
