Planning Advice for Soil Protection 2005
The Map is based on the assessment of the soil functions as shown in the Environmental Atlas Maps 01.12.1 through 01.12.5 (2009 Edition). Also used was the soil-association Map 01.01 (2009 Edition), from which the danger of toxic wastes, i.e. from rubble-soil associations, sewage farms and railway track beds, was taken.
The data of the Environmental Atlas Map 01.02 (2007 Edition) were used for the consideration of imperviousness classes.
