 of semivegetated salt-affected soils by means of field remote sensing. 
Rem Sens Env. 37:167-180.

Many recent attempts to map soils and related ecological phenomena are 
concerned with spatial patterns. There is a large diversity of
 approaches to determine 1) the actual parameters to be measured, 2) 
the most informative categories to be fomed based on them, and 
dependig both of the above, 3) the sampling locations and 4) the 
resolution of the map. This paper reports a field remote sensing 
project to meet the requirements of a detailed botanical and soils 
survez to understand salinity status of the Hortobágy region in east 
Hungary. The problem of association-level recognition of land cover 
is addressed in terms of quantitative description and ground 
resolution. It is concluded that the most characteristic six 
to seven vegetation association types are well identifiable 
based on their TM spectra using discriminant analysis/nonhierarchical 
clustering with half-meter ground resolution.
