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.
