ABSTRACT

For the purpose of defining location of points, coordinates that described according to a
reference systems are using which parameters has defined already. In surveying, the
base element is ground control points with their known coordinates in a reference
system. In every kind of surveying project, new coordinates are determining by using
coordinates of ground control points. Because of this, the projects realized by using
points which have low spatial accuracy and ground control point’s location errors will
be effect the position of new points location. Therefore the project’s accuracy will be the
same as ground control point’s accuracy used to determine coordinates.

In this study, because of the importance, the ground control points are examined in
Konya center districts. All the benchmarks and triangulation points have stored in
database with their referencing sketches. For efficiently use and managing database, in
ArcGIS 9.3 software, a Toolbar has compiled. With Toolbar, desired points can be
visualisate by one click in desired coordinate system and datum separately. With
compiling a WEB site all the coordinates can be searched without using Arcgis
software. Adding referencing sketches of points to the database, the knowledge about
the location and established real estate of points can be easily reached.
