analysis. Soils are classified into broad classes only. The 
thematic maps produced are to be transferred to a common map 
coordinate system. The study started in 1977 and will be com- 
pleted by the end of 1979. 
2. DATA 
The data acquired for the study consist of digital Landsat-2 MSS 
data, digital aircraft scanner data, aerial photography, tele- 
spectroradiometer data and various measurements in the field. 
Two test sites were chosen for intensive analysis:  Huittinen was 
used for general vegetation-soil relationship research, and Kuhmo 
for detailed timber inventory studies. Some details of the vari- 
ous data items are summarized in Table 1. The subsequent over- 
passes of Landsat data were not used in multitemporal manner, but 
in Kuhmo site both frames were needed to avoid cloud problems. The 
satellite-, aircraft- and ground data are used, however, in multi- 
Stage mode for timber inventory purposes.
