because contact data variations may differs very much 
from pixel to pixel and its possible to be wrong during 
estimations of water sources. 
Nearest future projects will be connected with joint 
application of passive microwave radiometer means 
with devices working in visible and infrared 
waveranges, in particularly during aeroplane and 
satellite measurements.
