THE WILD EK8 COORDINATE RECORDING
SYSTEM AND ITS POTENTIALS
Digitization in photogrammetry, as in other fields, is growing at an almost explosive rate. Coordinate
recording systems lie at the heart of digitization and, to be successful, they must be highly efficient and flexible.
In the four years since the EK8 was first introduced its system potentialities have grown, and are still growing,
to keep pace with the demands upon it. This paper shows the practising photogrammetrist what he can achieve
with the EIS.
The first part of the paper deals with the principles of the basic system and with the various output devices
which can be attached, together with the auxiliary modules such as time- and distance-selectors and a real-time
coordinate-transformation device.
The second part of the paper is devoted to a discussion of the uses of the EKS8 in its various configurations, with
typical examples of operating speeds. Particular emphasis is given to the practical problems which can arise
in the high-speed recording of large quantities of data. Information, drawn from practical experience, is given
to show how these problems may be solved.

APPLICATION OF ORTHOPHOTOMAPS IN HIGHWAY WORK
The use of orthophotomaps for location and design of highways as well as for operation and maintenance is
explained.
Directions and recommendations for the production of orthophotomaps are given with regard to:
scales of aerial negatives and maps, focal distances of aerial cameras and overlap of photographs,
location of stereo-models in relation to map sheets, assembly of road design, property, map, contour lines
