ABSTRACT 
Aerial photographs and electrooptical records from satellites are 
analyzed from the point of view of cartographic distortions. 
Existing cartographic databases (maps) are submitted to polemic 
from the point of view of storage of environment information. 
It is suitable to store the areal elements of environment in 
conform maps ? Equivalent representation for the maps of environ- 
ment is formulated and analyzed. 
1. INTRODUCTION 
Most of information of environmeent, which are represented in 
maps, are areal elements. The great part of existing maps in 
Czech and/or Slovak Republics is in some sort Of conform carto- 
graphic representations. It is understandable that the areal ele- 
ments of environment are deformed in the conform maps. This fact 
leads to idea to define some equivalent representation for the 
maps of environment.
