ABSTRACT
The purpose of this article is to present some aspects related to the stages of digital cadastral mapping process for Iasi city created at a scale of 1:500 and based on the digital photogrammetry technique, and to the accuracy of results. The photogrammetric works carried out for the digital cadastral map of Iasi have consisted in: schedule the flight of the photogrammetric unmanned aircraft, taking aerial photos, georeferencing, aerial triangulation and digital stereophotogrammetry, taking up the digital imaging, data processing and deliver of final result. The cutting-edge photogrammetry technologies have enabled the elaboration of the digital cadastral mapping of Iasi by orthophotomap on which geographic elements such as property boundaries, road infrastructure, woods, rivers, etc. have been vectorized. The mapping content of the cadastral map has therefore been ensured. Currently the specialists are increasingly using the digital photogrammetry to elaborate and update the digital cadastral maps at various scales. The progress the computer science has made in the automation of aerial imaging acquisition, storage and processing has led to the development of the geomapping photogrammetry technologies.

Keywords: digital photogrammetry, digital cadastral map, aerial photography, orthophotomap, vectorization.
