The basic map is produced using the photogrammetrical
methods / rectification, ortophoto and machine plotting/.
The entire undertaking is completed in stages adapted to the
actual economic needs and the production abilities of the
institution. For agricultural areas the first stage in the
production of the planimetric map is the determination of
property boundaries.
For introductory investment projects of communities as
well as country areas having intensive agricultural production
land morphology is included in the basic map. ItJpLs drawn from
existing topographic map in a scale of 1:5000 or 1:10000, by
photomechanical means.
For city and metropolitan areas, we produce in the first
stage a planimetric and contour map, and in the next stage
an inventory of underground industrial network /e.g. sewer
system, water maints/ is carried out.
In this report , the stereoplotting method of the basic
map plotting will be described, which is most widly used in
the region of southern Poland, together with organizational
and economical aspects.
Indeed, a map of certain regions is produced by a combi
nation of methods, hawever these are relatively small areas
and these methods remain marginal to the photogrammetrie
work carried out in the company.
The map is drawn upon a graphical basis, however sporadi
cally in order to record land plots in digital form coordina
tes are recorded.
2. TECHNOLOGY OF PLOTTING OF THE BASIC MAP USING THE STEREO
PLOTTING METHOD.
Individual stages of plotting are shown in figure 1.
Work begun after receiving instructions from the United Geode
sy and Cartography Enterprice ”GEOCART" in which is stated
our object to be mapped, scale and map contents.
The given areas are administrative units having defined
borders on the topographic map / 1:25000/. The surface area
varies between 600 - 800 km.
The first act is the execution of analysis of already
existing network and mapped material on the given terrain
/point 2/. On the object usually exists an elementary network
/triangulation net, polygon networks / which served as aides
in drawing up maps in the scales 1:25000, 1:10000, 1:5000.
This network is not sufficient with respect to density and
sometimes even with respect to accuracy for large scale map
ping. In certain parts of the object, there may also exist
large scale maps produced for the fulfillment of immediate
needs. In result of the analysis some regions of object are
