the eastern part of Bornholm, cf. Fig. 7. □ Faustskizze, angefertigt bei einer Erkundung (1994) von

graphic picture of the advances during the
field-work. Hence it is expedient during the
reconnaissance to draw a sketch of the
boundaries and the topography, Fig. 9, as a
memory-aid to be used when at the end of the
day the results of the working sessions have
to be brought up to date. However, by a
newly developed computer system the draw-
ing can be done simultaneously with the sur-
veying, thus enabling immediate graphic con-
trol of the measurements.
Data stored in a field computer are struc-
tured in forms which can be accepted and
understood by most computers. Their struc-
ture encompasses both raw data, e.g. hori-
zontal and vertical angles, oblique distances,
height of instrument and reflector, the num-
ber of the actual points, and text description
(alpha-numerical code), both of them in up to
12 ciphers or letters. For calculation of spatial
co-ordinates of measured points, an EDT-
programe is applied, which can read raw data
and perform a co-ordinate calculation of
c. 1000 points and stations in 20-25 seconds.
Most field computers can compute coordi-
nates synchronously with the measurement
of the point. It is, however, an advantage in-
stead to store raw data, because this makes it
possible to search for data errors. Such errors
are very rare. All surveys refer to the official
