Global Geoportal for Remote Sensing Images Centers

Vanessa Cristina Oliveira de SouzaGilberto Câmara

The objective of this work is to propose a geoportal capable ofintegrating the catalogues of the different images centers without these centershaving to migrate their current computational architectures to a specificarchitecture. In this work, the mediator architecture is considered a flexibleand 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 forimplementing this architecture, will also be analyzed. As a demonstrationprototype, we have integrated the CBERS data distributed by INPE in anexisting geoportal.
