(in reference to ÜIR). Also the implementation of basic
identifiers of owners - tenants, i.e. identification numbers of
citizens and identification numbers of juridical bodies
(connections to ROB and ROR - about 1 million of iden-
tifiers) and others will be finished.
The works should be finished in 1998.
b) SGI
The SGI (DKM) must in future replace actual disponible
KN map fund. The solution of this research project has been
concentrated on creation of programming systems and
technologies needed for restoration of these bases and their
conversion into the form of the digital cadastral map (DKM)
and for continual updating (maintenance) of their contents
to correspond with the contemporary legal situation
documented in the SPI database [10].
The programming system for creation, actualization and
utilization of the DKM database was elaborated in the
project solution framework. It concerns the applicative
superstructure of ordinary graphic software MicroStation,
version 5. The applicative superstructure of this general
graphic SW is the MicroGEOS system. It is at disposal for
all workplaces of cadastral offices in the CR including user's
and reference handbooks and training data [11]. For exter-
nal KN users a commercial programming system of similar
parameters has been elaborated which will be distributed
under the name DIKAT.
The MicroGEOS operates under the database system
dBASE IV and the integrating environment is ensured
through the MS DOS operating system. Inner format for
vector data is DGN, for raster data RLE, event. CCITT or
TIFF.
The MicroGEOS in user's environment of MicroStation
enables in the process of transformation of present map
bases into the digital form to establish and maintain the
DKM database through the creation of new original maps
even using (through rearrangement) original (present) map
bases.
The MicroGEOS enables to carry out basic functions for
creation and updating the DKM. It secures standard outputs
realization according to state standards. It makes possible to
perform check functions for the right geometry and topology
of the DKM as well as ensures the perfect interconnection
between the SPI and DKM [12].
According to the decree of CÜZK ref. No. 598/1995-23
dated 30.3.1995 the MicroGeos is applied as a uniform
graphic system for the DKM maintenance in the CR.
Application of the programming system MicroGEOS and
creation of the DKM database in workplaces of cadastral
offices will remarkably increase the operativeness of their
services for the KN users. The MicroGEOS above all will
mediate the direct interconnection of the SPI and SGI
databases. Furthermore it will accelerate and with upgraded
precision check the overhanding survey sketches for changes
of the KN contents and mediates introduction of their
veryfied results into the DKM digital database. It will enable
719
to localize operationally the original proprietary boundaries
of parcels from maps of former land cadastre especially in
land blocks to restore proprietary relations to real estates.
Last but not least it will mediate information yielding from
the DKM database (e.g. KM duplicate) through the form of
automated output from a computer in the real time by
means of a plotter or a laser printer.
It is extremely difficult to accelerate the conversion of
present map bases of the KN into the DKM form due to
a large number of acquired data. Actually, the whole map
fund of the KN is needed to be transformed into the digital
form and to be checked as to correctness of introduced data,
to be updated its contents, and to be created conditions for
continual maintenance of the created DKM database.
Respecting the immediate needs of accelerated forming of
this source localization database such conditions have to be
created, so that all disponible capacities would be employed
for transformation of present map bases into the digital
form [13], [14], [15], consequently also capacities of
potential users of this database. The works would be
finished till about the year 2010 [9].
One part of the project solution in the VÜGTK was the
mutual interconnection of the KN database with the SZBP
and STI data [16]. The interconnection of the SPI and
SZBP databases facilitates e.g. procedure of the ZBP points
protection and maintenance. The join of the SGI and SPI
KN databases to STI information efficiently raises the use
value of the STI databases, especiall for users from
municipal sphere [17]. The STI database utilization as a
graphic environment for processing and maintenance of
basic control nets survey raises again the operativeness of
the SZBP data utilization [3].
The proper solution of the STI ensures ZÜ. It resulted in
elaboration of the Fundamental Base of Geographic Data
(Czech abbr. ZABAGED) with utilization of Basic Map
1:10 000. The raster form of colour map image has been
elaborated for the entire CR territory and is presented as
ZABAGED 2 [18]. ZABAGED 1 will represent the vector
form of Basic Map 1 : 10 000 image with appropriate clas-
sifiers and other attributes of individual elements of the
topographic database contents. ZABAGED 1 shall be
realized on the entire CR territory in the century break.
3. APPLICATION OF PHOTOGRAMMETRIC METHODS
Till now we are not succeded in the full extent to restore
great traditions of the CR in operational application of
photogrammetric methods for creation and maintenance
large scale digital maps, especially the DKM. In the period
1987-1995 the utilization of photogrammetric methods
strongly receded, above all in the state administration. It was
due after the year 1990 especially to an enormous motion
and division of parcels during the real estates restitution
process. That is why the general renovation of cadastral
maps by new mapping had to be temporarily stopped. The
only one photogrammetric activity in operation of the state
administration is the maintenance of topographic maps at
the scale of 1 : 10 000 with graphical restitution on universal
