The paper presents the results of geophysical research conducted in the region where the so called ‘Gold Train’ was believed to be located. The surveyed site was located in Wałbrzych, at the 65th kilometre of the railway connecting Wrocław and Wałbrzych. The aim of the research was to verify the legend of the existence of the so called ‘Gold Train’ that was supposed to be located in the tunnel. The ‘Gold Train’ was believed to contain Wrocław's treasures. Three geophysical methods were used. Microgravimetric and GPR (ground‐penetrating radar) methods were applied to locate the void (tunnel), while the search for the train (a metal object) was conducted with the use of a magnetic method. Detailed geodetic measurements were used, including, among others, laser scanning. Due to complex terrain and geological structure, the negative results of the microgravimetric research was conclusive only in respect of one of the profiles. Due to high attenuation of electromagnetic wave by a shallow geological structure the scope of the GPR method was limited, however it was sufficient to confirm that such a tunnel does not exist. Despite difficulties related to electric lines in the researched area, conclusive results were obtained using the magnetic method. No magnetic anomaly with a shape or amplitude indicative of a steel train was identified.

Geological structure of the salt rock mass and its more than 700-year-old exploitation make the ''Wieliczka'' Salt Mine an important monument of material and natural values. One of the most interesting objects in the mine are the Crystal Caves, which are globally unique, because of salt crystals (halite) which are covering ceiling and sidewalls. Due to its uniqueness, caves are protected by law and a subject of preventive measures. Because of the tightening forces of excavations (convergence) Crystal Caves must be periodically monitored. It is estimated that the speed of convergence is from 0 to 2 mm/year. In order to monitor changes in the geometry of the excavation and deformation of crystals in the 1960s of twentieth century photogrammetric measurements were performed. They require a lot of work and time, and adversely affect the microclimate in the Crystal Caves. Presented in the article modern geodetic measurement techniques (laser scanning, total station) allow to obtain comprehensive data in a short time. It helped to receive an accurate analysis of the changes in geometry of caves. Proposed in the article measurement procedure determines the range of research, which was carried out in order to fully monitor the tested object. Due to the estimated speed of convergence and the accuracy of the applied technologies measurement series on an annual basis are planned. Comparative analysis of the data obtained in the future, give specific conclusions about the current impact of the rock mass on the Crystal Caves and help to improve prevention.

The significant part of the hydrography is bathymetry, which is the empirical part of it. Bathymetry is the study of underwater depth of waterways and reservoirs, and graphic presentation of measured data in form of bathymetric maps, cross-sections and three-dimensional bottom models. The bathymetric measurements are based on using Global Positioning System and devices for hydrographic measurements – an echo sounder and a side sonar scanner. In this research authors focused on introducing the case of obtaining and processing the bathymetrical data, building numerical bottom models of two post-mining reclaimed water reservoirs: Dwudniaki Lake in Wierzchosławice and flooded quarry in Zabierzów. The report includes also analysing data from still operating mining water reservoirs located in Poland to depict how bathymetry can be used in mining industry. The significant issue is an integration of bathymetrical data and geodetic data from tachymetry, terrestrial laser scanning measurements.

Geodetic surveys are used in an inventory of a lot of industries, including documentary of historic objects. One of the hardest historic objects that need to be inventoried are underground ones. Observations of rock mass movements and their consequences are very crucial issues, especially in the aspect of protection of historical objects, therefore it is needed to implement special methods (especially non-invasive) and specialist protection. In Poland there are few underground UNESCO mines and a lot of other objects of historical importance, for example built by Nazi Germans. Authors describe the following measurement methods: tacheometric surveys, terrestrial laser scanning (TLS), leveling and as supporting methods: Airplane Laser Scanning (and its product: LIDAR), Global Positioning System and satellite images or geophysics methods. There were inventory surveys conducted in Project Riese (German form-Giant) in Góry Sowie, Central Sudetes (Poland), is the biggest mining and building project of Second World War Germany. Until today, due to the lack of documentation, the purpose of these construction is uncertain. There are only hypothesis rather than facts. Currently, six underground complexes-Osówka, Włodarz, Soboń, Rzeczka, Jugowice, Gontowa, Książ Castle are discovered in the area of Góry Sowie. There are some speculations that all complexes were supposed to be combined. Some of the researchers of Góry Sowie secrets claim that kilometers of tunnels are still able to be discovered in the future. During the inventory the combination of classical measurements technologies and modern surveys methods were used-terrestrial laser scanner, tacheometry and GNSS measurements. Authors used collected data to analyze geometrical relations between objects Complex underground and ground of Osówka. This allowed to verify location of objects in relations to each other which was not previously presented in research. Many sections and profiles of excavations, sketches and maps were made. METODY INWENTARYZACJI HISTORYCZNYCH OBIEKTÓW PODZIEMNYCH Słowa kluczowe: pomiary inwentaryzacyjne, podziemne obiekty historyczne, ALS, dziedzictwo kulturowe Streszczenie Procesy zachodzące w górotworze wymagają, aby każdy podziemny obiekt podlegał inwentaryzacji i kontroli. Na szczególną uwagę zasługują przede wszystkim historyczne i zabytkowe obiekty wydrążone pod ziemią, które powinny być objęte ochroną i działaniami umożliwiającymi ich rewitalizację, czy udostępnienie dla turystów. Ochrona tego typu zabytków wymusza kompleksowe podejście do problemów ich zabezpieczania i stosowanie różnego rodzaju metod inwentaryzacji, przede wszystkim ze względu na ich zazwyczaj i niepowtarzalny charakter. W Polsce znajduje się kilka podziemnych kopalni wpisanych na listę Światowego Dziedzictwa UNESCO oraz obiektów ważnych pod względem historycznym, np. wybudowanych przez Niemców w czasie drugiej wojny światowej. Proces inwentaryzacyjny takich obiektów opiera się na kilku ważnych aspektach, m.in.: rozpoznaniu warunków geotechnicznych i hydrogeologicznych ota...
