8 FINLAND 
The highway planning has experienced a decisive change at the end of the year 
1959. Previously the use of the aerial photographs was limited only to stereoscopic 
investigations and to the use of photograph enlargements as work maps. Now has the 
Board of Roads and Waterways set up a special Mapping and Computation Section 
for photogrammetric highway planning and for the mechanical mass computations 
therewith. The following instruments have been purchased for the present for this 
purpose: an autograph A8 with registering device EK3, a Balplex Plotter, and for 
the control surveys a Tellurometer. The computations are for the present carried 
out in Sweden with a middle-sized electronic computer Facit EDB. 
The Board of Railroads has begun to use the aerial photography and large-scale 
stereoscopic mapping of railway yards and areas. 
' Agreat number ofrectified enlargements of aerial photographs have been delivered 
annually to be used as base maps in making reclamation and draining plans and water 
supply investigations. 'The photographs for these purposes are delivered as diapositive 
films so that photostatic copies can be taken of them to be used as work maps. 
The planning of long-distance telephone cables is carried out almost wholly on aerial 
photograph basis. The mapping ofthe cable lines is done on photograph enlargements, 
which are delivered as diapositive films. 
The capital of Finland, Helsinki, has adopted periodically repeated aerial photo- 
graphy of the city area to supervise the building activities. 
FINAL REVIEW 
As a general statement can be said that the photogrammetric methods have won 
an established position and come into general use in Finland. As the greatest 
drawback could perhaps be mentioned that the photogrammetric methods suited 
to the cadastral surveys have not yet become established. 
The photogrammetric research in our country has not had chance to develop 
in such a degree as would have been desired. The greatest reason for that lies perhaps 
in the lack of a research institute and necessary instruments. However, an improve- 
ment in the situation is to be expected in the next years e.g. therefore that foundation 
of a Surveying Research Institute is under consideration. Also the establishment of 
the photogrammetric education is bound to help the matters in this respect. 
From the aforementioned situation it follows that the applied photogrammetry 
has had chance to develop ahead of the basic research. Therefore the most important 
goal of the next years should be the basic research of the applications which are 
already in use and finding out their advantages.
