Grid Service for Environmental Data Retrieval and Disasters Detection Based on Satellite Image Analysis

Considering that one of today´s biggest global concerns is related to the climate change and its imminent undesired effects, we present the approach of creating and offering a public Web service to provide real-time access to environmental data and information. One of service´s direct usages is natural disasters detection, but it could be further used for developing complex statistics and prediction generators, or for other environment related applications. The data is extracted from a satellite imagery repository implemented on a Grid infrastructure. For testing the capabilities of the service for different type of users, a visualization and interaction Web application has been developed. The service is integrated in the MedioGRID system.
