A large number of new developments have influenced digital mapping in the last few years. The main advances beyond the conventional analogue map preparation encompass [a] mapping conduct with the help of vector- based graphic software to [b] complex Geographic Info rmation System (GIS) - based mapping environments which provide a common spatial domain and context for data and also [c] attempts to provide platforms for interactive web- based mapping. These improvements also affect the field of planetary geoscientific mapping. As in Earth - oriented geosciences planetary mapping nowadays is mainly conducted in and supported by integrated GI systems. Thematic maps in planetary geology are created either systematically in a framework of survey-coordinated and agency - funded scientific mapping project, or they have emerged from broader scientific programs and individual geoscientific research on global, regional and local scales.
