PHOTOGRAMMETRIC ENGINEERING
Of particular interest is the further de
velopment of methods which serve to elimi
nate the systematic errors which may occur
in triangulated strips by means of corrections
applied to the photograph coordinates.
A major problem that still remains to be
solved is how to satisfy the need of especially
the many small photogrammetric organiza
tions for suitable computer programs. Many
of these organizations have neither the neces
sary experience nor the access to a sufficiently
large computer to use large sophisticated
programs and they would be best served by
small programs for specific purposes. As yet,
only the U. S. Coast and Geodetic Survey
and the National Research Council of Canada
have made it their policy to publish their
programs.
