Summary:

The project presents a new concept of developing geodetic control and measurement networks on the basis of a double option solution which employs ASG-EUPOS active geodetic network. The concerned network has been established in the area affected by mining activities, within the territory of the city of Jastrzębie Zdrój. Points were distributed over the distance of 7070 m and formed
a typical linear network. The proposed concept of measurement and observation development options made it possible to obtain average accuracy of the coordinates after levelling at 4,2 - 4,9 mm (option one) and 1,2 - 1,5 mm (the alternative option of the solution). Apart from the high accuracy of coordinate tracing, the proposed concept of setting up geodetic networks also offers another important advantage: a practical ability to get networked via the ASG-EUPOS network which is available on common basis and free of charge for the daily measurement activities.
