The purpose of this study is the analysis, comparison, optimization and complementation of spatial data, acquired by various methods, with various and different standards; in order to produce three dimensional urban models with adequate quality for city planners and urban planners. Pilot application area of the study was determined to be Taksim Cumhuriyet Square. In the end of accuracy comparison, data taken with terrestrial laser scanner method for the buildings covered with reflective materials and geometric data taken with terrestrial photogrammetry method on translucent buildings are used. The model, which was visualized in this way, became dynamic with animations. When the scale of application is considered, no need for DTM or DEM study has been seen necessary. In the conclusion of the study, the presumed hypothesis has been tested on a selected pilot implementation area and it was proved to be feasible. It is a method that can be used in other urban regions, too. The resulting model is a three dimensional square model, powered by terrestrial laser scanners which use real photogrammetric data. It is processed onto three dimensional maps in its real scale (1/1 scaled). It significantly contributes to the complimentary three dimensional model of Taksim Cumhuriyet Square and urban planners' micro-scale planning studies. The model presents all the technical information with integrated data sets which are necessary for permanent square arrangement. (C) 2012 Elsevier Ltd. All rights reserved.
