Producing a three dimensional model for the university of Baghdad campus using GIS environment

Abstract

It is known that the creation of a 3D map has become a necessity for some applications especially in managing of city planning. In this paper, Geographic information system tools were used to create the 3D model; these provide the best visual interpretation of spatial data that supports a project designer in terms of planning and decision processes. This paper presented a simple strategy to create a 3D model for the University of Baghdad, Aljadrya Campus using GIS tools that would be integrated with a SketchUp software. A certain number of reference control stations were created and distributed within the whole study area using GNSS static technique, which is required for a georeferencing process. The methodology of this study also includes an assessment procedure regarding the positional accuracy and length by measuring arbitrary buildings and points in the field work of this study. Then, the resulting 3D model may be employed for clearly planning, creating new buildings and updating specified networks. Moreover, it may be used for getting positioning coordinates and length that have an accuracy level of less than 10 cm in addition to the ability to utilize it by new students for exact inference of locations. It is worth mentioning that the whole work of this study was uploaded to the GIS website online for use as an open source data.
