No data reduction or generalization in transferring or digitizing took place. The different attributes represent the data in a generalized and specific manner. The most specific attributes describe the vegetation to the genus level of classification. The specific genus levels have also been categorized into 13 general vegetation classes. The attributes contain numerical codes and descriptors.
Modifiers also exist representing percent of vegetation cover and tree height.
