formed by the combination of: 
Union of rape seed and green manure (I) and root crops (II) 
and arable land 2 (II). 
- The union of all land-use types characteristic for 
better soils. 
Error: to & small extent, green manure and 
root crops occur on sandy soils. 
4, Grassland 
land with green manure (II). 
Intersection of grassland and young cereals (I) and grass- 
  
- This results in a preciser definition and narrowing-down. 
Error: the intersection of young cereals (I) and green 
manure (II) is classified as grassland.

- The purpose is to unite all areas not relevant for soil 
survey. 
When combining two classifications, the sequence of the operations is important: 
Union of industrial area (I) and industrial area (II) and 
those spectral classes, which are most relevant for soil survey, should be 
processed at the beginning, because pixels, which have already received a 
classification cannot be re-classified upon further work. 
When looking at the results of 
combination (photo 12) and at 
the interpretation map (map 2), 
an interesting distribution of 
important soil associations can 
be discerned, which is useful 
for a small-scale pedologic 
regionalisation of the Neu- 
münster area. Areas of glacial 
outwash and glacial drainageways 
are clearly distinet form loamy 
morainic material. Transitio- 
nal areas show by a mixture of 
the colours representing loamy 
and sandy classes. Further 
information is contained by the 
distribution of sandpits, co- 
niferous forest, peat cuttings 
and grassland according to the 
principle of analogy, as explained 
previously 
Although this method does not 
replace detailed mapping of 
particular area, it serves to 
improve upon existing general
