The introduction of cadastre in Romania as a matter of national interest and community obligation, in order to guarantee property rights, real estate market development, credit guarantee, etc., is dependent upon the digitisation of the basic cadastral plan at a scale of 1/5000 all across Romania. The technologies used are varied and the work is complex, involving large expenses. Within this context, the present work aims to determine whether and to what extent this cadastral plan can be obtained through the transformation or vectorization of the existing national orthophotoplans. The methodology is based on comparing the vectorised cadastral plan with the one obtained by level surveys, considered as a reference, and applied to six units (land areas) located in two different places. Comparisation has focused on the main stages of the vectorization process, namely on easily identifying parcels (property estates) and tracking their borders, on markings positioning accuracy, on surface errors that may arise in relation to real errors, and on aspects regarding performance, including hardware and software logistics. The results are good, fully satisfactory, suitable for practice in many categories of surveying projects and particularly advantageous in terms of performance that is ensured with minimum equipment. Some difficulties arise only in special cases on site, when additional evaluations and monitoring is required.
