Concept of web service for real-time satellite imagery dissemination

The paper presents Software as a Service approach to the real-time satellite imagery dissemination. Proposed system architecture comprises 4 logical units, namely the data acquisition, management, coverage server and client modules which are organized in an linear layout. Web Coverage Service (WCS) query protocol is extensively utilized as an interface for exchange of data between the modules. The proposed system is designed for serving nearly real time pre-processed satellite imagery to remote users in the form of WCS tiles. A software solution for serving time-varying images through the WCS protocol is proposed. The paper discusses several prospective applications of the system.
