The article describes the basics of the design and examples of practical implementation of systems (platforms) for creating and providing thematic services using Earth remote sensing data. The principal features of such systems should be, firstly, the possibility of integrating territorially distributed information resources, including heterogeneous ground-space data and calculation and analysis modules, and secondly, the fullest possible automation of these processes, ensuring interaction with untrained (in the sense of information technologies) user. It is shown that a service-oriented architecture can be the basic approach to creating such systems. Based on a comparative analysis of existing and promising information technologies, the necessary components of the Thematic Services Information Platform (TSIP) were selected. The constructiveness and feasibility of the proposed approach is demonstrated on the examples of practical testing of TSIP when creating thematic services.
