The architecture for data, security and application in Digital Earth platform

Abstract

Digital Earth platform is an application, service and decision support system, which integrates geo-spatial data acquisition, transmission, storage, processing, analysis, statistics and visualization. It realizes comprehensive management and widely application of different kinds of huge earth data under the geo-spatial framework and in a open environment. It should consider the continues growing of data and applications, as well as data security. According to the issues of how to safely use spatial data in Digital Earth platform, an architecture for data,security and application in Digital Earth platform was proposed in this paper. We call this architecture DOA(DOSA). In the digital earth platform on its goal is the Trusted Data. DOA(DOSA) and Trusted Data can provide data management, security grantee, application supporting for Digital Earth platform.
