GIS, EFFICIENT SUPPORT FOR URBAN PLANNING - FRAMEWORK OF TIMISOARA, ROMANIA

Geographic Information System (GIS) usually aims to producing maps and plans, managing network utilities (water-supply, sewerage system, mains, district heating, roads and railway system etc.), identifying the optimal location for an investment, the study of the impact of a certain objective upon the environment complying with the general policy of sustainable development. The consequence of the sustainable development implementation is a necessity of spatial system designing. This means that ensuring sustainable development presumes different Geographic Information Systems (GIS) because they give quick access of updating and analysing spatial databases. This paper presents the updating conception of the urban GIS database for Timisoara municipality, using knowledge from different sources of cadastre and GIS. It also highlights the connection that should be taken into consideration between the general cadastre and the specialty cadastres represented by the fact that the technical and economical inventorying of the network utilities must start from the primary information given by general cadastre, referring to parcel, area and land-use category. The importance of the paper lies in its role as an efficient management tool for a huge amount of spatial urban relevant data thus contributing to the optimization of the activity carried on by the local administrations. Nowadays, there is an increasing interest in 3D (three-dimensional) technology which can be seen also by major cities developing 3-dimensional models, and global technology companies developing solutions to capture, display and manipulate this type of data. Accurate cartographic feature extraction, map updating, digital city models and 3D city models in urban areas are essential for many applications, such as mapping of buildings and their heights, simulation of new buildings, military operations, disaster management, updating and keeping cadastral databases current, and also for virtual reality.
