Taking into consideration the components below and the aim
and accuracy of orthophoto image that will be produced, it can
be decided that the data source will be satellite image or aerial
photograph.
e |f aerial photographs of the interested area can not be
taken because of the physical, legal e.g. reasons, the
use of the satellite images will be necessary.
e The satellite images can be more economical for digital
orthophoto mosaic production of small areas in high
resolution and of wide areas in low resolution.
e [t can be more economical to use aerial photographs for
digital orthophoto mosaic production in wide areas
with high resolution.
The source can be satellite image or aerial photograph
depending on the scale of orthophoto map:
e |n case of orthophoto production from aerial
photographs, the scales of aerial photographs, which will be
taken depending on the scale, are shown in Table-3.

2 1/2.000-1/2.500 1/8.000-1/10.000
3 1/5.000 1/16.000-1/18.000
4 1/10.000 1/20.000
5 1/25.000 1/35.000-1/40.000

production of orthophoto map.
e In case of orthophoto producing from satellite images,
satellite images and its specifications, which can be
used depending on the scale, are shown in Table-4.

Table 4. The types of satellite image that can be used for
production of orthophoto map.
As it is seen in Table-3 and Table-4;
e |t is evaluated that base orthophoto maps, which are
needed for Master plans and application reconstruction
plans that contain 1 / 1 000 — 1 / 5 000 scales, can be
produced from aerial photographs,
e Base orthophoto maps, which are necessary for regional
plans and environmental arrangement plans in 1/10.000
and in smaller scales, are better to be produced from
satellite images.
In this context, orthophoto example on which the cadastral
boundaries drawn for development planning is given in Figure
I, enhanced orthophoto example for environmental plans or
regional plans is shown in Figure 2.

6. CONCLUSION AND PROPOSALS
The development of the society directly affects the urban area
and urbanization together with economic, political and cultural
structure. Urbanization in developing countries like Turkey has
many problems because of high population growth and push of
the rural. But the urbanization is inevitable and positive
development. The solution of the existing problems lies under
urban planning and carrying out these plans.
The nations who don't want to live their future by chance plan
development of their national, regional and urban areas. The
data and information gathered in local level are transferred to
administrative levels by generalization and evaluation and they
help strategic decisions. These decisions in national level are
reflected to the area by regional plan and urban plan.
Physical planning levels in Turkey are mentioned as regional
plan, environmental plan and development plan in Urban
Development Law numbered 3194. Also in the frame of
adaptation to European Union, statistical regional units were
formed and began to application. While the connection
between the national plan prepared in economic level and the
