The contribution deals with the contextual design of spatial data for regional development and land management purposes. Further development of information technologies, image processing techniques and contextual knowledge-based databases, together with the geographical networks environment, will provide quite new and considerably wider possibilities of using GIS. GIS architecture is open to incorporate new requirements of knowledge-based analysis and modelling, namely in connection with web designed spatial databases. The paper describes the role of remote sensing data and contextual modelling for the context-oriented geo-information and tries to provide a framework for the object hierarchy of classes and propose the ways of the structure and behaviour modelling.
