Pilot project of cadastral data distribution via Internet started at the end of 2001. Reason was a pressure from users who wanted faster and improved access to cadastral data. Motive of the Governmental Geodetic Authority of Serbia (GGA) was to use pilot project for testing technical potentials, but also to use it as a source of experiences for writing regulations that would legally formulate distribution of official cadastral data by using Internet. Starting assumption for the development 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, topographi...c maps, cadastral register, etc.), different operating systems and applicative software. Software design is based on OpenGIS/TC211 standard (WMS ver 1.0). Cadastar started as a pilot project in the town of Novi Sad, but during realization it has become an official system for cadastral data distribution. Results that were achieved were: data integration, faster response on user demands, some major municipality agencies has became direct users of new services. Making new regulations of this matter, data acquisition, data quality enhancement, etc followed project realization. Paper describes telecommunication infrastructure of city intranet as an environment for the developed application, application architecture and the data. Some statistics regarding the system exploitation will be also given.
