For the implementation of geodetic measurements connection points in a superordinate system are necessary. The totality of these connection points forms a geodetic basic- or fixed point-network.
The accomplishment encloses the investigation of existing fixed points of the land survey, planning of portal networks, marking of new - and affirmation of new and existing fixed points - above ground and underground, implementation of network measurements in the portal areas and advances, evaluation of measurements. The result is a preferably tension free basic network.
The measurements occur with the most modern total stations and GPS receivers. The evaluation of the measuring data and the network balance calculation occurs with approved software programs.
