GEODETIC AND LEGAL ASPECTS OF RIVER MEASUREMENTS IN THE OJCOWSKI NATIONAL PARK

In this paper the authors present the results of the tacheometric measurement portion of the Prądnik river flowing through the Ojcowski National Park (OPN). The coastline of the river is variable along its length. Does not coincide with the of the river evidence borders. The specificity of field work in the OPN requires the surveyor's knowledge of not only the law surveying, restrictions on protected areas as well. Methodology of work involves the use of different measurement techniques and the integration of gained data. The specific terrain makes it necessary to use different techniques and surveying equipment. The end result is a graphic design longitudinal profile of the river. Results for the longitudinal section above 3 km and 130 cross sections. In addition, the authors present a photographic documentation showing the coastline of the river and the stream at intervals of about 50 meters.The work will provide a base for further analysis in order to determine the flood zone of the mountain river. The problem of this analysis will be the subject of subsequent papers by the authors. ...

Geodetic survey line course of gas pipeline

Measuring the course of the gas network is possible using surveying. They make it possible to obtain sufficiently accurate results for the possibility of moni-toring the movements of the gas main, especially in the landslide areas. In planning the appropriate series frequency of testing, we can predict the displacement on what it is exposed, and in what period of time. Thanks to this professionals from the scope of strength of materials can calculate the deformation and strength of materials. This gives the possibility to obtain an approximate lifetime, exposed to damage, the gas main and take appropriate action before the damage becomes a fact. Damage to any gas main network extends as a threat to the environment. It also forms an obstruction to the existence of the population to which the transfer is interrupted, especially where, as in the case in question is a strategic network of supplying high pressure gas to Podhale.In the publication discusses the results of measurements and calculations for a line of high pressure gas pipeline DN 300 g in Borzęta, in the municipality Myślenice. Studied section of the pipeline is located within the newly established, clearly visible landslides. The object was measured by standard methods ...
