摘要：Digital Earth is a visionary concept and outlines a charming prospect for the public. This paper starts from the concept and technologies of digital Earth and analyzes the architecture of geo-spatial information services of Digital Earth according to the developing trend of requirement for geo-spatial information services. As a promising prospect for Digital Earth, the digital measurable images (DMI) from aero-space and land borne geo-referenced image are introduced and their working principles are given in detail. Through analyzing how DMI achieve the four functions of Digital Earth including searchable, visuable, measurable and minable, the conclusion that DMI can satisfy the need of Digital Earth, especially cyber geographic environment, is testified
