Description
Summary:Natural disasters force to upgrade existing spatial databases and archive services in order to support massive user requests for data and information which describe emergency region. It is often the case when necessary information is not located in one place but distributed within a set of information sites. Both these circumstances—massive requests and data distribution—interfere to provide user with requested information in timely manner. Presented work proposes an integrated approach in increasing data-providing efficiency. The approach is constituted by two principal components: (1) upgrading spatial database content (what to provide) and (2) enhancement of exchange tools (how to distribute). The first component—content upgrading—is implemented by enriching data model with ranks that provide designated users with estimations of suitability of data sets for description of occurred or potentially possible disasters. This component aims to spare user time while searching and choosing appropriate data. The second component—enhanced exchange tools—should give users the set of services enabling to receive data from any remote EO data center in timely manner. Implementation of this component is analyzed in wide context—from ordinary data uploading via ftp client–service application to broadcast data dissemination. Analysis is resulted in formulation of dissemination strategy.
