Detail measurements to be carried out in an area of 1 hectare will
cost 149.66 dollars, according to the prices suggested by Chamber
of Surveying and Cadastral Engineer in Turkey for the first half of
the year 2003 if classical measurement techniques are used. These
classical measurements for the whole mission area of 10 x 10 km
can be completed at least in three — four months. Production of the
map by satellite images can be completed in one and half months
after the obtaining of satellite images.
Land slope maps can be obtained from software that uses satellite
images to evaluate and do several analyses. Thus, these maps can
be used as base maps when the irrigation network is planned for
the region. It can also be utilized from satellite images in the
production of hydrographic maps for the planning purposes.
Constructed irrigation and road networks in the planning stage
essentially form the blocks, which are subject to the distribution,
as well. When the land constellation blocks constituted on maps
are applied to the field, 1 — 2 m differences can appear at the block
corners that are contrary to the land features which actually
describe the original block edges and corners in the field, if the
block corners are got from the maps produced by using satellite
images and remote sensing software. In the land consolidation
works carried out by using classical measuring techniques, some
arrangements for the differences, which extent to 3 m and appear
during the application and control measurements of the blocks, are
actually done to fit to the original features on land. For this reason,
road and irrigation networks and block edges are shifted to fit the
digitized and computed values of the block corners and edges to
the original features on land. From these two cases, it can be
suggested that results from satellite images show better accuracy
oc
level with 1-2 m errors than those from classical techniques.
Similarly, in a land consolidation project, it is important to
determine the stationary establishments and facilities on land such
as bridges, fruit gardens, buildings, houses, power lines and etc.
for distribution of blocks and for classification to be done in the
region. Since classification and distribution works get difficult,
when these stationary establishments and facilities do not exist
especially on the present cadastral and topographic maps. Another
important issue to be mentioned here is that it is mandatory to
assign the stationary establishment or facility on the land
consolidation field to its original owner during the distribution
stage of the consolidation work. Satellite images beside give an
ability to determine those stationary establishments and facilities
and they also provide a medium where the determination can be
done very rapidly. Thus delays in the project procedures and
processes can then be avoided mostly.
7. CONCLUSIONS
In the planning stage of a land consolidation work;
e Determination of present state of project area,
e Land works and classification processes,
e Formation of blocks (water management, drainage and
road systems),
e Determination of stationary establishments
above is done by using satellite images, they can be completed in
half of the time that classical techniques require and the project
can cost 35 times cheaper than that the classical techniques cost.
When cadastral, classification and satellite images are put one
right after the others by matching the features, which appear on all
of them, the fields which are not registered and can not be seen on
cadastral maps can easily be determined during the land
consolidation work together and registered to national treasury.
After all, in the next step, they can be evaluated under the cover of
land reform and distributed to the farmers who are not the owner
of farmland. At the same time, government also has a financial
source from these earned fields.
