Global Geoportal for Remote Sensing Images Centers

The objective of this work is to propose a geoportal capable of integrating the catalogues of the different images centers without these centers having to migrate their current computational architectures to a specific architecture. In this work, the mediator architecture is considered a flexible and efficient way of building a global geoportal for remote sensing images. The three components of this architecture, portal, mediator and data sources, will be analyzed and specified. The web services technology, as a solution for implementing this architecture, will also be analyzed. As a demonstration prototype, we have integrated the CBERS data distributed by INPE in an existing geoportal.
