Nowadays, cities are developing and changing
rapidly due to the increases in the population and
immigration. Rapid changing brings obligation to
control the cities by planning. The satellite images
and the aerial photographs enable us to track the urban
development and provide the opportunity to get the
current data about urban. With the help of these
images, cities may have interrogated dynamic structures.
This study is composed of three steps. In the first
step, orthophoto images have been generated in order
to track urban developments by using the aerial
photographs and the satellite images. In this step, the
panchromatic (PAN), the multi spectral (MS) and the
pan-sharpened image of IKONOS satellite have been
used as input satellite data and the accuracy of
orthophoto images has been investigated in detail, in
terms of digital elevation model (DEM), control points,
input images and their properties. In the second step, a
3D city model with database has been generated with
the help of orthophoto images and the vector layouts.
