主　　题：Satellite imagery Earth observation archives spatial data infrastructure collaborative workflows security reliability 

摘      要：Earth observation satellites produce large amounts of images/data that not only must be processed and preserved in reliable geospatial platforms but also efficiently disseminated among partners/researchers for creating derivative products through collaborative workflows.Organizations can face up this challenge in a cost-effective manner by using cloud services.However,outages and violations of integrity/confidentiality associated to this technology could arise.This article presents FedIDS,a suite of cloud-based components for building dependable geospatial platforms.The Fed component enables organizations to build shared geospatial data infrastructure through federation of independent cloud resources to withstand outages,whereas IDS avoids violations of integrity/confidentiality of images/data in sharing information and collaboration workflows.A FedIDS prototype,deployed in Spain and Mexico,was evaluated through a study case based on a satellite imagery captured by a Mexican antenna and another based on a satellite imagery of a European observation mission.The acquisition,storage and sharing of images among users of the federation,the exchange of images between Mexican and Spanish sites and outage scenarios were evaluated.The evaluation revealed the feasibility,reliability and efficiency of FedIDS,in comparison with available solutions,in terms of performance,storage consume and integrity/confidentiality when sharing images/data in collaborative scenarios.
