From the tables it is evident that more and more mapping is being 
done in the scales 1:400 and 1: 500 while the percentage of maps in the 
scale 1:2,000 is diminishing. This tendency will probably be further 
emphasized during the years to come. The reason for this is, as mentioned 
in the introduction, that planning in closely populated districts to a 
greater extent than earlier demands accurate, large-scale maps. 
Another evident tendency in the production is that pictures are being 
used more and more often for the measuring of coordinates in connection 
with the planning of roads, streets, conducts, and buildings. Besides, 
aerial pictures have increasingly come into use for the interpretation of 
ground conditions in construction areas.
