The Transylvanian region of Romania is a place of rich history since ancient times, where the original natural environment around architectural heritage sites or buildings has not been severely altered by urban development. Unfortunately, many such places are left by the authorities to degrade or totally collapse for lack of funds, vision or initiatives. The current paper addresses the potential of Unmanned Aerial Vehicles (UAVs) in the assessment of a viable and feasible prospect of restoration on a 19th century mansion that belonged to a nobiliary family. UAV use is rising in many industries and has become very popular in the last decade, but for survey engineering and related domains they represent a quantum leap in technology. Integrating UAV-acquired data and structure from motion software, has enabled modern techniques to obtain useful metrics from the field, accurate photorealistic 3D models for visual inspection, structural damage analyses, architectural rehabilitation-restoration, conservation and spatial analysis of the surrounding area. In this work a socio-cultural planning and design process is explored and presented to improve the local community and inclusion in a tourist circuit based on the regional potential, as well as an evaluation of accessibility derived from a vector-raster database that highlights the central position of the cultural heritage in regards to the axis of circulation between the important metropolitan areas and the local tourist attractions. This established workflow of modern topographic and construction measurements is fully integrable into the architectural process, building information modelling, heritage conservation and reconstruction.

The systematic registration of real estate on the territory of a state represents the way to the rapid development of the market economy by reducing transaction costs, securing property rights, reducing or avoiding corruption and attracting investors. This work presents the way to create a systematic cadastre sector in the form of a case study, in accordance with the systematic cadastre procedures at the level of Romania, and its impact on sustainable development. In Romania, systematic registration is realised in the Eterra electronic database starting with the year 2015, together with the establishment of the National Agency for Cadastre and Land Registration (ANCPI) program 2015-2023. Registration is carried out exclusively at the level of the administrative-territorial unit (U.A.T.), respectively commune, city, municipality or at the level of one or more cadastral sectors, depending on the contract concluded between the executor and the local municipality. The procedures and stages of carrying out systematic cadastre works are regulated by Law number 7/1996 on cadastre and real estate advertising and the Regulation of July 9, 2014, on approval, reception and registration in the cadastre records and land register, as approved by the Order ANCPI number 700/2014. The financing of the program is made from three different sources: own revenues of the ANCPI in the amount of approximately 900 million euros, non-refundable external funds (European Union) in the amount of approximately 312 million euros, allocations from the budget of the units administrative-territorial through co-financing and is done free of charge for property owners.
