Figure 2: Map revision. Part of the topographic map sheet Ósthammar 121 SV, scale approximately 
1:50 000. Left: old map, revised 1982. Centre: SPOT PAN 1990. Right: newly produced map based 
on aerial photos (altitude 9 200 m) from 1989 and field control in 1990. 
SPOT data has not been used in the production of the new map, but it has been available as an aid. 
In the study, however, it has been shown that SPOT images is a useful tool for the planned future 
revision of this map; regarding roads, built-up areas and clearings.
