PROBLEMS OF GEOMORPHOLOGICAL MAPPING Geographical Studies No. 46, Warszawa 1963

RESOLUTIONS ADOPTED AT THE CONFERENCE OF THE SUBCOMMISSION

ON GEOMORPHOLOGICAL MAPPING

During the sessions held in Kraków (3, 5, 6 May), in Toruń (10 May) and in Warsaw (12 May) twenty lectures were presented together with a selection of the detailed geomorphological maps produced in 14 countries. The Conference Par-ticipants considered these maps to be incomparable because of the scope of content and the modę of its representation. From the standpoint of the further development of geomorphology comparable geomorphological maps are needed. They ought, therefore, to be constructed on the following principles:

1. The detailed geomorphological map must result from a geomorphological mapping based on field investigations. Field data must be plotted on a detailed topographical map wherever possible supplemented by aerial photographs.

2. The detailed geomorphological map ought to be produced on the scalę of 1 :10,000 — 1 :100,000. Those maps allow the relief to be exactly represented and most of the features to be located true to scalę. Furthermore, those scales permit the detailed geomorphological maps to be produced with relative easy. It has been suggested to carry out field researches on smali scalę maps (e.g., 1 :25,000) and to publish them on a larger scalę (e.g., 1 :50,000).

3. The detailed geomorphological map’s aim is the complete representation of the relief from which its character, its history and its further development ten-dencies can be deciphered. Hence it follows, the detailed geomorphological map’s aim is to represent the relief from the standpoint of dynamics. The detailed geomorphological map must inform of the distribution and of the relation between landforms whose dimensions, appearance, origin and age are known. The detailed geomorphological map must, therefore, include (a) morphographic, (b) morpho-metric, (c) morphogenetical and (d) morphochronological data.

4. The geomorphological content, i.e., all of the features occurring in the area investigated, must be plotted on contour lines by means of multicoloured signs true to scalę. Both the signs and the colours must inform of the morphographic and the morphometric data, of the origin and the age of every landform.

5. Dating the landforms is a necessity because it introduces us into the map’s content, and into the chronological order. Furthermore, it permits the relation between the landforms and geomorphological history to be established, and the further development tendencies to be foreseen.

6. In case of structural and depositional landforms the structural (lithological) data should be indicated by means of signs somewhat differentiated.

7. Regard paid to these principles will mark a step forward in the production of comparable maps, and it will allow the morphographical, morphometic and
