Education
During the project it became clear that in general
the top management of the ministry sectors was not
aware of the possibilities given by geo-oriented data
bases. Moreover, in each of the sectors there were a few,
mostly younger specialists dealing with GIS-technology.
Their work was amateurish and without any concept. It
was decided to create so-called „information islands" in
each sector of the ministry. In order to establish knowl
edge communication lines among different sectors an
education system was designed composed of four parts:
informational education (for all levels);
top management education (for managers);
engineering education (for engineers);
operational education (for operators);
The education system for each level follows the concept
of the phases of the production lines.
Cost models
Besides numerous technological solutions, the project
„Computerization of the geodetic evidences" has also
given the estimation of the time needed to generate the
geo-information infrastructure for the entire territory of
Slovenia (20,000 km2). This estimate is based on the
production for one map sheet of scale 1 5 000 for topo
graphical data bases multiplied by the total number of
map sheets (2600).

Fig. 8. Time estimates of the production line.
Total time needed for all map sheets per layer: 2600
maps x 40,8 hours 106080 hours. Total time needed
for all map sheets for all layers: 7 layers x 106080 hours
742560 hours. With 1800 hours per man year makes
a grand total of 412 man years for all map sheets and all
layers. This grand total figure includes only the opera
tional generation of the topographical part of the geo-
information infrastructure.
Conclusions
The project „Computerization of geodetic data bases" in
the Republic of Slovenia has initiated numerous activi
ties. Not only in the field of geodesy but also in other sec
tors of MEPRP. The practical experience gained during
the project execution can be summarized as follows:
technical expertise:
organizations elaborating the project have proven
that the generation of the digital data bases can be
software/hardware independent provided that clear
standards are available;
additional education for all hierarchical levels is re
quired to enable understanding of geo-information
infrastructure and technical communication;
the project gave a concrete estimation about the
time needed to generate the geo-information infra
structure for the entire territory;
organizational aspects:
non-understanding of the new technology by top
management appeared to be the main obstacle
slowing down the modernization of geodetic ser
vices and other sectors of MEPRP. Also the tradi
tional linkages to existing technology and trans
formation from socialistic to market economy are
factors which seriously affected the modernization
efforts;
proposed technological solutions have indicated
that all geodetic services have to be reorganized to
generate the geo-information infrastructure;
new legislation based on the results of the project
will define the procedures to generate the digital
data bases;
new programmes for education, research and
development will have to be created;
new cost models for different phases of generating
the data bases will have to be developed;
financing:
the project showed the concepts for the execution
of pilot projects to test new technology before im
plementation. Implementation will be incorporated
into annual plans of geodetic services step by step.
This gradual approach will enable proper selection
of the equipment and adequate education.
