In Poland, keeping a register of areas threatened by mass movements and landslides monitoring is the responsibility of the staroste1 resulting from the provisions of the Environmental Protection Law and the Regulation of the Minister of the Environment. Pursuant to the Act, the staroste is obliged to observe areas threatened by mass movements of land and areas where these movements occur. According to the Regulation, "for areas endangered by mass movements and areas where these movements occurred, a monitoring is ...

The studies of the rock mass movements on considerable depths can be carried out based on the network of geodetic points, present in the mining excavations. Such a network is very unfavourable in a sense of geometry, because it is, in a large part, built of open traverses. Often the only way to raise the accuracy parameters of such a network is making the azimuth measurements on selected sides of the network with the use of gyrotheodolites. Applying the carried out gyroscopic observations in the levelling of the n...

The urban structure of the old town quarter in Sandomierz belongs to the oldest and most interesting Polish architectural and archaeological sites. In this part of the town there are several objects written into the register of historical monuments. The location of the town on loess grounds, of a large thickness, has caused a lot of problems for the owners of real estates and the managers of technical infrastructure. This is the result of the characteristics of loess. Loess affected by external factors (rainfall) ...

Ground based radar interferometry is one of the currently used, remote measurement technologies allowing to determine the displacements of the monitored area. This technology use a radar operating in the microwave band, which emits a beam in the direction of the monitored area, and then after reflection processes and registers it in the form of radar image. In order to determine the value of the displacement it is necessary to perform at least two measurements on the basis of which the interferogram is generated. ...
