Our conceptual approach to system of cataloguing and distributed access to remote sensing data creation is considered. At present the system is realized as pilot project at the Scientific Centre for Aerospace Researches of the Earth of IGS of NAS of Ukraine. The approach takes into account the world experience of geospatial data infrastructures designing. The profile of standard for airborne and spaceborne imagery metadata is developed based on the international standards and real requirements of geospatial information consumers. The architecture of the system is described and some features of its hardware and software realization are considered.
