ABSTRACT

In Republic of Croatia the Law on State Survey and Real Estate Cadastre regulates the
maintenance of cadastre and its gradually adjustment to the real estate cadastre,
Currently, is in progress the establishment of real estate cadastre by the new cadastral
surveys for 5% of the Croatian territory. For the remaining areas establishment is
planned by individual parcel translation. The most important and difficult precondition
is cadastral plan geometric accuracy improvement (homogenization). Pursuant to Law
Article 71 and Article 12 of the Ordinance on the cadastral survey and technical
reambulation, geometric accuracy improvement is done by comparing orthophoto with
cadastral plan thru identical points. This paper analyzes the number and selection of
identical points, as well as compares three different computer programs which can
perform local transformation. Quality of geometric accuracy improvement was observed
thru several analyses.

Keywords: homogenization, digital cadastral plan, local transformation, identical points, control points
