dc.description.abstractGPS Virtual Station technique fundamentally depends on determination of a virtual point by GPS that is just about 1,5 meters above the ground or a platform surface and then to the use of it by other surveying and/or photogrammetric instruments such as a total station and/or a camera. Thus, the technique offers a challenge in terrestrial photogrammetry to determine the coordinates of control points distributed on each facade of any object in any size and in a reference system, which is globally available, and without using a network of points set up on the ground and surrounding the object. The technique is also capable of determination of camera perspective centre’s coordinates by the use of GPS Virtual Station which is determined by the GPS antenna. In this process, first, GPS antenna is set up on a tripod with a leveled triprach to collect GPS Virtual Station coordinates and then it is removed from the triprach and replaced with a camera (i.e. digital camera) in a similar way of that can even be followed with total station to be used for the measurement of control points on the facades. So, it means that the network of points to be set up for the measurements of control points on the objects in interest and which is the most cost effective part of a over all project is removed, no more hustle for it, and three unknown parameters are now known values when considering that the camera perspective centre is determined as GPS Virtual Station, and so that the number of control points on the facades can be reduced, and there is no location limitation for chose of points, so that they can freely be chosen at any time (even in the middle of a measurement section if some kinds of problems are met, such as GPS signal blockage and object coverage problems) at any where around the object and finally, every object measured using this technique in any part of the world can easily and spatially linked and referred to one another with respect to the same reference system. In this study, the technique mentioned above was utilised to create a final product as an originally textured virtual reality 3D photogrametric model of a historical site, which is a unique sample of a cultural asset remained from its own time. It is Aladdin Mosque built up at the top of the Aladdin Hill where takes place at the centre of Konya. 3D model of the site is also ready to be put into the internet and onto a CD to distribute and interact in a GIS environment. As a final outcome of this study, it can be stated that the technique proposed here represents an encouraging performance in the point of accuracy, and project speed and economy as well.en_US
