c) Thematic properties: 
- correlation between the spectral bands based on the 
calculated principal components: 
50 % of the information contains in -the 1st component 
30 2nd 
20 3rd 
This result shows the relative small correlation bet 
ween the spectral bands of the MK-4 camera in compari 
son to other known mu1tispectral systems (MKF-6, SPOT). 
- Recognition of natural objects: 
The quality of recognition and interpretation of some 
natural topographic objects is given in table 3. From 
this follows that the multispectral mode allows a little 
better identification of some linear objects and of 
different agricultural areas.
