A number of satellite image sources on meteorology and environment are available over the Gulf of Mexico (GOM). Those satellite images are taken periodically in order to observe the weather changes. However, users usually face several problems when they want to search, retrieve, and combine images from multiple data sources. Without an adequate system and personnel for managing data, the magnitude of the effort needed to deal with such large and complex data sets can be a substantial barrier to the GOM research community. As a result, a mediator-based data integration system is proposed and developed to retrieve and integrate the images of satellite observational systems over the GOM.
