a) SPI 
The result of this research project solution is the trans- 
formation of the distributed SPI data on personal computers 
(PC) [8]. The local databases of the SPI are now being 
maintained operationally in local networks in the database 
system dBASE IV. The integrating environment is ensured 
by MS DOS and Novell NetWare operating systems. The 
programming system INFORMACE (Engl. meaning 
INFORMATION) of the VÜGTK - for information output 
from the SPI and the programming systems 
AKTUALIZACE and POMOCNA EVIDENCE (Engl. mean- 
ing ACTUALIZATION and AUXILIARY EVIDENCE) 
of the Cadastral office at Ceské Budéjovice - for information 
maintenance, are established and utilized in all cadastral 
offices in the CR. The identity of central and local databases 
is secured by batch processed files on magnetic media in 
regular time periods. The remote transfer of the SPI data is 
now being introduced through the Bulletin Board System 
(BBS/PC). 
The level of data processing has increased. Information is 
yielded on workplaces where it has been acquired and 
processed. This partial realization means a really remarkable 
improvement of services for the KN users. Extracts of the 
KN can be done automatically in the real time. 
In the digitization program of the SPI [9] new data will be 
putted into the existing database in the following period. It 
means above all the addition of proprietary relations to real 
estates on the entire state territory, especially in land blocks 
which were used by so called "socialist" organizations 
(involving about 10 million of parcels and 3.5 million of 
owner's folios). Furthermore there must be added quali- 
tative specifications of individual parcels in the form of soil 
valued ecologic units (Czech abbr. BPEJ - about 14 million 
of parcels) and codes of village-parts in build-up areas
