Item type:Article, Access status: Open Access , Od modelu do numerycznej mapy przestrzennej(Wydawnictwa AGH, 2010) Maciaszek, Jadwiga ; Gawałkiewicz, Rafał ; Gawałkiewicz, IzabelaThe development of mining digital cartography includes automation of making maps based on the information contained in databases, clear layout and legibility of their content, wider introduction of 3D models of large fragments of mines, application of new measurement techniques (e.g. laser scanning) in obtaining data for these maps. The authors present types of 3D models, discuss the deformations resulting from the application of the projection and give the examples of the modelling of objects connected with salt mining.Item type:Article, Access status: Open Access , An inventory of opencast mining excavations recultivated in the form of water reservoirs as an example of activities increasing the retention potential of the natural environment: a case study from Poland(Wydawnictwa AGH, 2023) Szafarczyk, Anna; Gawałkiewicz, RafałThe article presents examples of the employment of various geodetic measuring tools used for a detailed inventory of lake basins and shorelines. The measurement and analysis covered three post-mining open pit excavations recultivated as water reservoirs: two in Krakow (Bagry Wielkie and Bagry Małe) and one in Piaseczno (Piaseczno Sulphur Mine). Attention was paid to the factors that reduce the accuracy of the inventory of some flooded post-mining excavations, which determine the degree of usefulness of the morphometric data set for later analyses. According to available estimates, only about one-third of all water reservoirs in Poland have detailed geodetic documentation in the form of bathymetric maps. This documentation usually does not include water reservoirs of anthropogenic origin formed after the flooding of post-mining excavations (mines: sand, gravel, clay, limestone, sulphur, aggregates, etc.). The authors suggest the introduction of a document known as a reservoir documentation card and the creation of a database covering all anthropogenic water reservoirs. Considering the water deficit in Poland, it may be necessary to develop a detailed database of water resources in the short term.Item type:Article, Access status: Open Access , Określenie charakterystyk dokładnościowych wybranych instrumentów laserowych(Wydawnictwa AGH, 2005) Gawałkiewicz, RafałFor several years the market of surveying equipment has been dominated by reflectorless laser instruments - telemeters built into tachometers and scanners. They make the instrumental base for many important producers of surveying equipment in the world. In this article, the results of the tests on selected instruments i.e. laser tachometer TCR 303 - Leica and first in Poland panoramic scanner Callidus - German firm Callidus Precision Systems GmbH, Halle are presented. Given in the article results of the carried out experiments allow more detail characteristic of the precision of tested instruments in terms of the accuracy in the measurement of the distance up to 32 m. They also give the answer, regarding the orientation of Callidus scanner in the relation to the selected reference prisms, which has a significant influence on the accuracy of the combination of individual scanning images into one image. The accurate analysis confirms the possibility of applying parameters in orientation (lengths and directions for a bigger number of prisms) obtained in the scanning of reflectors, which in practice, allows the definition of the situation of a scanner in space, with a great precision and without the use of angle-measuring auxiliary instruments in the process of the reference of scanning observations referring to the points of the measuring base.Item type:Article, Access status: Open Access , Zastosowanie skanowania laserowego w diagnostyce obiektów podlegających wpływom eksploatacji górniczej(Wydawnictwa AGH, 2006) Maciaszek, Jadwiga ; Gawałkiewicz, RafałIn the article the results of studies aiming at the definition of the degree of the usefulness of the technology of automatic laser scanning in the process of rectification (bringing back to vertical) the inclined houses in the mining areas. The laser monitoring covered two objects: a five-storey building in Ruda Śląska was measured with the Callidus scanner (to compare the results also with the electronic total station Geodimeter 610+Serwo and Nikon NPL-352), while an eleven-storey built of pre-fabricated concrete in Katowice was measured with the scanning total station Trimble 5500 DR 200+Serwo. The measurement results from the Callidus scanner were obtained with the Extraktor program. The determination of the components of the inclination vectors of the edges of the segments of both building and their sum was graphically presented in the AutoCAD program. The obtained results of the laser scanning indicate that this method allows precise diagnosis of the object and is helpful, particularly in the cases when the object gets deformed unevenly.Item type:Article, Access status: Open Access , Orientacja sytuacyjna danych w oparciu o wskazania kompasu elektronicznego Callidusa w inwentaryzacji trudno dostępnych pustek naturalnych i górniczych(Wydawnictwa AGH, 2006) Gawałkiewicz, Rafał ; Szafarczyk, AnnaVery popular now is a subject of protecting structures, which are the results of the miners generations work. The same refers to the natural, often unusual caves, which could be noticed and then restored and opened for the public. Such works could extend the region attractiveness. Many of those objects, according to their shallow covering could be dangerous for the surface and the buildings and structures located on this area. Nowadays the using of fully automatic laser scaners could make easy such works as iventorisation and documents bringing up to date. In the article there are presented results showing possibility of using electronical compass, which is an element of panoramic scaner Callidus, to situational orientation the clouds points when classical instrument orientation is not possible. Using the gyrotheodolite Gyromat 2000, produced by DMT it was possible to calculate the real accuracy of Callidus electronic compass.
