ABSTRACT
This chapter is written as a result of experience gained while working on the pilot phase of the York Archaeological Assessment. One of the greatest problems with the use of archaeological data in today's GIS is the conflict between multi-dimensional data and essentially two-dimensional display technology. It is obvious that pseudo-threespace representation must be used in displaying such an image, but conventions must still be developed to allow this mass of information to be understood and manipulated in any meaningful fashion. Unless the designer is prepared to use different formats for colour and monochromatic displays surely an unnecessary waste of effort except in exceptional circumstances it is necessary to consider all forms in which a map may be displayed right from the design stage.
