<strong>GEOGRAFSKI</strong> <strong>INFORMACIJSKI</strong> SISTEM KOT ORODJE ZADOLO^ANJE PRIORITETNIH OBMO^IJ PRENOVE MESTdr.

Model temeljina identifikaciji klju~nih kazalcev arhitekturno urbanisti~nega, socio-demografskega, ekonomskega in ekolo{kegastanja v pozidanem mestnem prostoru. Za vsakega od teh kazalcev dolo~a spremenljivke, prvinein na~in vrednotenja. S pomo~jo meril vrednotenja, ki se dolo~ajo v odnosu do povpre~ne vrednosti oziromaveljavnih normativov, ocenjuje relativne vrednosti prostor. Z dodajanjem ute`i, ki naj bi jih mesto dodajalov skladu z razvojnimi strategijami, pa je mogo~e izbrane prostorske enote poljubne velikosti glede na nujnostprenove razvr{~ati v vrednostne kategorije oziroma prioritetne liste.Na koncu je dodan prakti~en preizkus modela na izbranem obmo~ju mestnega sredi{~a Ljubljane in analizaprednosti in slabosti modela.KLJU^NE BESEDEgeografski informacijski sistem, urbana prenova, urbanizem, prostorsko planiranjeABSTRACTGIS as a tool for determinig priority areas in town renovationThe article presents a GIS model that enables not only collecting and analyzing data as well as monitoringthe spatial status but also enables determination of priorities or urgent areas for renovation. The modelis based on the identification of key indicators for architectural and urban, socio-demographic, economicand ecological conditions in the built up urban areas. For each of these indicators the variables, sub-variablesand criteria for evaluation have been determined. The criteria for evaluation that have beendetermined in relation to the average value or valid standard enable definition of the relative values of space.By adding weights, chosen by the cities in accordance to their development strategies, it is possible to classifythe selected spatial units into categories or priority lists, indicating the need for renewal.In conclusion there is a practical test of the model on a selected area in the urban centre of Ljubljana andthe analysis of advantages and weaknesses of the model.KEYWORDSgeographical information system, urbanism, regional planning, town planning, urban renovation, townrenovation177
