“…The problem is that many soil types have to be shown, and that their spatial variability is high (Bornand et al, 1989), particularly when the final maps are of medium to small scale. Finally, the documents thus obtained are difficult to use, which is an inconvenience that has caused misunderstanding and underutilization of cartographic work in soil science (Coulson & Ellehoj, 1993;Msyana et al, 1987;Valentine et al, 198 1).…”

“…A method consists of showing the maximum of soil characteristics for each polygon, using graphic techniques (Bertin,198 1) or alphanumeric codes (Coulson & Ellehoj, 1993). A complementary technique uses a legend with an additional report in which, using the same symbols, similar soil units are grouped according to a predefined classification.…”

Before computerized techniques were used, a paper soil map had to fulfill two functions: memorization or managing a maximum of data, and communication or transmitting a minimum of pertinent data on a given problem. Computer‐based techniques and, in particular Geographic Information Systems, enable the management, analysis, and easy organization and presentation of data about soils. An apparent first step would be to take older data in paper maps and convert them into a geographic database format using digitizing and other computer techniques. However, such work may be insufficient, as is demonstrated by analysis of the specific example of the European Communities Soil Map. Therefore, we propose a new relational structure for pedological or soil science information based upon the main conceptual concepts used during conventional cartographic work. This “Soil Spatial Organization Model,” or SSOM, is a computerized framework for coherent description of the geographical variability of soils, combined with other environmental criteria. It makes no prejudgment on the type of processing of such data. It stresses the importance of starting with the determination of the type of soil organization such as the identification of spatial units and their relationships to permit cartographic representations that show specific themes. © 1994 John Wiley & Sons, Inc.
