The paper discusses the principles governing the conversion of an analogue, reference geomorphological map into a digital map. This was done using a fragment of the 1:500 000 Geomorphological Map of Poland published in 1984, with topical editorship provided by L. Starkel and cartographic layout by K. Trafas. For the purposes of the paper, the southern part of Poland, situated within the boundaries of the geographic macroregion of the Carpathins, was selected (Olędzki, 2007). The methodology of converting an analogue map into a digital map comprised the process of data collection, encoding and processing. In this process, we used the ArcInfo, ArcView, Arc Map and Erdas Imagine software. In effect, a map was created as well as a spatial database of geomorphological information. The nature of the input data, that is the existing analogue Geomorphological Map of Poland, determined the way the data were compiled. The map’s sheets were scanned, vectorised and encoded. The basic problem was to define the method of encoding and graphic marking of data in the digital map. The geomorphological content of the Digital Geomorphological Map of the Carpathians was expanded by an additional information layer, i.e. the raster underlay of the 1:500 000 Administrative Map of Poland, derived from the Atlas of the Republic of Poland.
