Study on Web Service-Based Remote Sensing Data Service Platform for Digital Earth

Digital Earth is the Virtual Earth integrated with Earth’s mass, the three-dimensional, dynamic data by geographical coordinates. It plays a major role in the field of spatial information. Remote sensing satellite data is an important part of spatial data resources. However, remote sensing satellite data is massive, multi-source, heterogeneous . In order to realize the digital earth remote sensing data sharing and interoperability by masking the differences between remote sensing data to integrate remote sensing information resources in a unified Digital Earth. The article study the web service for remote sensing data sharing and interoperability on the basis of a full investigation for the characteristics of multi-source remote sensing data, This article raise a Web Service-based Earth remote sensing data service system solution with reference to the framework of OGC Web Services Space, so as to provide powerful data support for digital earth.
