Terrestrial laser scanning (TLS) technology is increasingly used in surveying, construction and architecture. The potential of the data obtained by this method creates the possibility of its versatile application also in conservation and revitalization of monuments, archaeology or history. The use of this technology during the creation of architectural documentation of a historic building greatly facilitates the acquisition of comprehensive information about its actual condition in a fast, non-invasive and very precise manner. Thanks to digital technology, it also creates the possibility to accurately interpret the condition of an object and present its model in a virtual space. This technology provides the ability to transfer acquired image elements with high accuracy of their mapping to plans and designs prepared by architects and contractors. It is also possible to maintain high technical standards in the processes aimed at the preparation of the required graphical studies, thanks to the use of the point cloud obtained in TLS. One of the most important advantages of using this measurement method is the possibility of combining it with data from e. g. from photogrammetric tools, which gives the possibility to fill in the missing elements creating a more complete picture of the needed data. This paper presents the implementation of terrestrial laser scanning technology as a non-invasive method for the modelling of walls and buildings of the so-called "green field". Revers BIM on the example of the measurement of the facades of the buildings of the old market in Jarosław. This technology allows for preparation of precise architectural documentation including: projections, sections, elevation views, 3D models or multimedia visualizations. The use of TLS for cultural heritage research also enables the preparation of fully complete documentation for conservation and restoration works aimed at maintaining the current state of monuments or even at reconstructing their damaged architectural elements.

A tourist attraction is everything that raises tourists’ interest and stimulates them to travel. The revitalization of the railway infrastructure elements and transforming them into objects that serve tourist needs may positively affect urban space, as well as contribute to socio-economic development. Foreign and Polish examples show many tourist attractions created on the basis of closed railway lines, degraded railway areas or railway stations. A ride by narrow-gauge railway, a cycle route created on a former railway embankment or even a walk along the promenade alongside the railway viaduct can be an attraction in itself. Such objects become a magnet that attracts tourists to the region, and at the same time stimulate demand for other tourist services. The aim of the article is to identify and classify tourist attractions that have arisen as a result of revitalization of the railway infrastructure. The article is divided into three parts. In the first one, the essence of the revitalization of the railway infrastructure is characterized. The second explains the term “tourist attraction” and the classification of tourist attractions, while the third contains practical examples of revitalization of inactive elements of railway infrastructure transformed into tourist attractions.

The study of displacements of engineering structures using geodetic methods consists in determining the displacements of the structure in relation to the adopted reference system or in determining the geometry of individual structural elements or the entire structure. The geometry of tower objects is measured cyclically. In the case of telecommunications towers, the most common geometry research is the deviation of the tower axis and the turning angles of the tower at its individual levels. The article presents the methodology and results of the telecommunications tower geometry research obtained for a steel three-legged tower with a height of H = 32.11m. It is a steel tower with a typical structure. The structure in the projection is described on the plan of an equilateral triangle. In the corners of the tower there are curbs in the form of solid round bars. Angular observations were made in two positions of the telescope to selected points on the legs of the tower. The heights of the points on the foundations of the tower were obtained from measurements using the geometric leveling method. The heights of the points at each level of connecting the segments were determined by the trigonometric leveling method based on the measured zenith angles. The measurement points were related to the geometric axes of the tower legs at the connection points of individual segments. The tower displacement parameters were determined from geodetic measurements with the Theo010A theodolite.

Sheet piling is commonly used in various areas of special construction. Embedded in the ground before carrying out excavation works, sheet piling constitutes an enclosure and protection for the designed excavation. It is a temporary enclosure and protection for excavations made for communication structures, launch shafts built for microtunnel construction, etc. In order to assess the quality of the engineering works related to the construction of sheet piling, measurements were made of straightness and verticality of the sheet piling used for the technological chambers. The measurements concerned two technological chambers of 7.2 and 6.4 m height. Inventory measurements were made using a total station of 1” accuracy and a leveling staff with the appliance of the socalled projection method. The two technological chambers were built in the investment area called “Infrastructure construction for rainwater drainage, water supply and sanitary sewage collection from the John Paul II International Airport Kraków-Balice.”
