Abstract 
On the basis of FMP and available spaceborne multispectral 
scanner data, various relevant surface phenomena have been 
investigated, due to their spectral charachteristics. The 
analysis of multispectral and multitemporal data demonstrates 
the requirement to optimize bandwidths and center frequencies 
of MSS systems. The additional utilization of medium infrared 
bands, > 1,1 pm, seems indespensable. 
Introduction 
Research in the field of remote sensing must be concentrated 
on investigations concerned with the spectral behaviour of 
relevant phenomena due to environmental and seasonal changes 
and finally with the development of earth scientific models 
on the basis of multispectral and multitemporal data. The 
development of sensors, and, in particular, of optimally appli- 
cable spectral ranges, with variation of flying altitude accor- 
ding to ground resolution, must be adapted to these conditions. 
The main investigations were carried out on the basis of FMP 
airborne MSS-data on test-site 4, southern bavaria. 
In comparison with FMP 2 other testsites were investigated: 
1) High alpine landscape of the Monte Rosa Massiv, Swiss/Italian 
border 
Typical mediterranean landscape in southern Tuscany/Italy.
