the influence of soil colour on spectral data is in 
progress. 
It is also proposed to examine the scatter plots of 
MSS data of the nine test sites for dates throughout 
the season in order to establish the boundaries of 
'good' agricultural data as required by the Screen 
algorithm (XSTAR) (Lambeck et al., 1978). The average 
yellowness over the testsites which forms the basis of 
the XSTAR haze correction algorithm will be investi 
gated.
