ABSTRACT: 
astral data distribution via Internet started at the end of 2001. Reason was a pressure from users who wanted 
ata. Motive of the Governmental Geodetic Authority of Serbia (GGA) was to use pilot 
a source of experiences for writing regulations that would legally

project for testing technical potentials, but also to use it as 
formulate distribution of official cadastral data by using Internet. 
of the more advanced solution for data integration and distribution was to respect existing 
hardware, software and organization of GGA. Large cities were chosen because there were the strongest motives for solving these 
problems. Also, the best telecommunication infrastructure was there. The proposed solution is based on Internet technology. 
Software development is based on n-tier architecture. System for data distribution integrated data from different sources (cadastral 
maps, orthophoto, topographic maps, cadastral register, etc.), different operating systems and applicative software. Software design 
is based on OpenGIS/TC211 standard (WMS ver 1.0). 
Starting assumption for the development 
the town of Novi Sad, but during realization it has become an official system for cadastral data

followed project realization. Paper describes telecommunication infrastructure of city 
application, application architecture and the data. Some statistics regarding the system exploitation will be also given.

2. eCADASTRE SOLUTION FOR NOVI SAD of integrated DGP, cadastral and address system data 
for the town of Novi Sad 
  
  
Starting project assumptions and requirements specified that the Oct initiative from JP Informatika Novi Sad, major developer 
designed solution would have to respect current conditions 2001 lof the municipal information system of the town of Novi 
(technical, organizational). All of this has limited number of Sad to get cadastral maps of the town 
possible options for the system design. Large cities were chosen Oct. Proposal of changes and supplement 
because the interest for solving problems related to cadastral 2001 l[/ees for using state survex a 
data distribution was the biggest there. Also, cadastral offices 
for these cities were places where data for the whole town 
territory were already available. Finally, the intranet network 
was already developed there. Nov.
