The term - cartographic modelling refers to the process of creating qualitatively new information, usually in the form of map, which has otpimum thematic content from user's point of view. Geographic data, which represent reality through spatially defined objects, are the basis of each process of cartographic modelling. The most common objects are: points, lines and areas; they can appear both in analogue (continous), as well as in digital (discrete) form. In case of assessment of environmental changes on Borne Sulinowo postSoviet military ground I used for cartographic modelling information contained in relational GIS database, which was created on the basis of data acquired as a result of interpretation of panchromatic aerial photographs taken in 1951 and 1993, as well as data collected through field works. Process of cartographic modelling comprised many analytical functions. The most important were: re-classification, overlaying of spatial objects and neighbourhood analysis. New map contents, which were formed on the basis of these analyses, enriched cartographic model of the analysed area through adding new thematic layers. It enabled to acquire for the study area new additional information about spatial and logical relations between various environmental components.
