[en] Nowadays a real effort is devoted to the formalization of raster – image – geographic information. From conceptual design to relational modelling, norms and standards are proposed by agencies as well as commercial companies, for implementing raster data in spatial databases and GIS. At the same time, query languages are enhanced in order to promote the use of raster data in relational spatial algebra. Besides, normalized schemes make raster interoperability possible between distributed GIS, and encourage the emergence of Web services dedicated to raster processing. Hence, it can be expected that raster geographic data will play a major role in the coming spatial data infrastructures.
