Realization of geodetic network for monitoring of landslide area near Trebenice

Popis výsledku v původním jazyce

České středohoří Mts. area has long been modeled by geological activities including landslides. Near the city Třebenice there are several active landslides, one of them is exceptional because its long-term activity disrupts just two linear constructions, both road and a railroad. Therefore the landslide was intensively monitored in the past several years and is quite well mapped thus. The aim of this paper is a realization of special geodetic measurement suitable for the landslides monitoring. The system of measurement is based on spatial polar method in combination with GNSS (static method). The biggest problem in landslide monitoring is stabilizing of the stable points for the shift determination, especially in this case, because the monitored area and its neighborhood is very unstable. Therefore the GNSS method was used in each monitoring epoch for absolute shift determination of whole area. The relative shifts were determined by the total station measurement connected to points determined by the GNSS measurement (in each epoch). Before the measurement the a priori analysis was realized in special software PrecisPlanner 3D and for complex processing and the adjustment it was used the special geodetic software EasyNet, which enables the robust analysis of outliers. The measurement was processed as a spatial network. Results convincingly describe changes in the area including the accuracy of their determination.
