The vegetation map provides us with information about the natural resources and its distribution in the landscape. With in-depth knowledge of the classes and their contents, management schemes can be implemented for farmers, environmental authorities and other users.

The method of data collection for vegetation mapping in Norway is primarily based on fieldwork and the use of aerial photos. A magnifying stereoscope is used in order to get a three dimensional image of the landscape. In the field, the vegetation gets classified into types, and borders are drawn around these.

The classification system used for general mapping divides the vegetation types into 10 groups, which in total comprise 45 vegetation types and 9 other land cover types. The system used for detailed mapping is compatible with the general system. It has three levels, namely groups, types and subtypes. There are 24 groups which together account for the main types of vegetation. The system contains 137 types, which normally correspond to plant communities on different levels. In turn, the majority of types are further divided into subtypes which correspond to plant communities on lower levels (association, sub-association). Regional variants or special local communities are usually counted as types. In both systems a number of additional symbols are used for important information which is not included in the type definition.
