In spatial planning, the 3.dimension of the existing environment 
must provide an input to design. In other words, urban plans 
form spaces to be lived rather than being two dimensional 
drawings. In the course of time, i.e. it is necessary to be able to 
imagine how the spaces which would be formed in 4. 
Dimension, reflect effects.

and age between 50 and 100 
Figure 12. The ratio of mass/space building of the plots 
With this aim, by the help of the contour lines passing in the 
area (Figure 13), the Digital Elevation Model (DEM) of the 
study area has been achieved (Figure 14). By the help of 
contour lines that are obtained from z values of each point in the 
study area, more comprehensive information about the buildings 
located on the sloppy structure of land has been collected.

In addition to the works mentioned above, 3-Dimensional 
Modelling Studies would also ease perception and decision 
making (Figure 15-16). With this intention, the general view the 
Digital Terrain Model (DTM) which is occurred by drawing the 
3-Dimensional (3D) views occurred from the drawing of the 
building on the cadastral building block in the study area, on the 
Digital Elevation Model (DEM), is shown on the Figure 16.
