Three-dimensional digital technology is important in the maintenance and monitoring of archeological sites. This paper focuses on using a combination of terrestrial laser scanning and unmanned aerial vehicle (Phantom 4 pro) photogrammetry to establish a three-dimensional model and associated digital documentation of Beaufort castle (Arnoun, South Lebanon). The overall discrepancy between the two technologies was sufficient for the generation of convergent data. Thus, the terrestrial laser scanning and phantom 4 photogrammetry data were aligned and merged post-conversion into compatible extensions. A three-D dimensional (3D) model, with planar and perpendicular geometries, based on the hybrid datapoint cloud was developed. This study demonstrates the potential of using the integration of terrestrial laser scanning and photogrammetry in 3D digital documentation and spatial analysis of the Lebanese archeological sites.

Abstract. The paper examines the possibility to create a three-dimensional model of cadastral objects – cadastral parcels and buildings, exploring different spatial data acquisition technologies. Four cadastral parcel and part of the buildings situated in them are selected for the range of the task. Self-contained objects located in buildings have not been examined. The objects are located on the territory of Lozenets District, Sofia, which is highly urbanized part of the capital. In order to create a three-dimensional model, classical land surveying measurements with a total station and mobile laser scanning were performed.In addition, the acquired data is assessed. It is made by comparing measurements of the building to the measurements of the registered point cloud. The assessment results show that the mobile laser scanning technology is efficient to reproduce high quality and accurate data for existing building structures due to MLS advantages – the large range, high accuracy, fast data acquisition and high level of detail.The paper is a part of Alexander Alexandrov master thesis.

The paper discusses the issues concerning the modelling of aerodrome obstacle limitation surfaces. They can help to detect obstacle in the flight path of an aircraft. To this end, digital relief and site models need to be created together with obstacle limitation surface models. A fast and effective algorithm of creating three-dimensional digital site model which uses airborne laser scanning (LIDAR) data is proposed. The 3D visualization and analysis of the model are also discussed. The paper presents the experimental Akis-AER software designed to detect potential obstacles around an aerodrome and assess whether it is safe to install a new construction or to increase the height of the existing one in the navigating space around the aerodrome.

Geodetic Control

The method of geodetic control of the road pavement using TLS is presented. The use of the terrestrial laser scanner can avoid some of the disadvantages of classical methods for determining the deformation of objects. One of the main of them is a small amount of information about the position of individual parts of the object, in this case, linear engineering structures. The proposed technique for terrestrial laser scanning of pavement in order to determine its actual spatial position and real geometric shape allows to perform the required set of works with the least labor and time costs, and also to obtain data for further monitoring. The technique involves the construction of a three-dimensional model of pavement for its evaluation over a certain time interval with a similar model. In order to determine the coordinates by the TLS, the special spheres of known diameter were used. During the measurements, tribrachs on tripods were used, in which the spheres alternately changed to reflectors to eliminate the centering error. The accuracy of determining the coordinates of the temporary survey network relative to the base station was no more than ±27 mm. The accuracy estimation of the temporary survey network coordinates made in the “LeicaGeoOffice” software is presented. The network of permanent stations in Ukraine was used to determine the coordinates, the errors were calculated as the RMS deviation.

Laser scanning allows the acquiring of spatial data about existing objects. It is used as a modern inventory technique, most often in the creation of archival or conservation documentation. It gives the opportunity to obtain a very large amount of spatial data of the facility thus helping to improve operations in the field of conservation but also reduces the margin of error in the inventory and then design documentation. It is useful due to the growing BIM technology, through which three-dimensional models of existing objects of various scales are obtained. This article presents research comparing the traditional measurement method and the modern one with the use of a laser scanner. The research is a compilation of the duration of architectural inventory techniques as well as the accuracy of the measurements made and of the following architectural drawings. The result of the research is a relative percentage ratio showing the acceleration of inventory works with a simple construction object using modern assistive techniques compared to the traditional method.

Gypsum Karst

In the region of Siesławice (near Busko-Zdrój, Poland) there are unique phenomena of gypsum karst. Atmospheric factors caused numerous gypsum outcrops, canals and underground voids. The article presents the possibility of using non-invasive gravimetric surveys supplemented with geodetic measurements to illustrate karst changes occurring around the void. The use of modern geodetic measurement techniques including terrestrial and airborne laser scanning enables to generate a digital terrain model and a three-dimensional model of voids. Gravimetric field studies allowed to map the anomalies of the gravitational field of the near-surface zone. Geodetic measurement results have made it possible to accurately determine the terrain correction that supplemented the gravimetric anomaly information. Geophysical interpretation indicate the presence of weathered rocks in the near surface zone and fractures and loosened zones located surround the karst cave.

Technological Means

The issues related to the introduction of innovative methods, technologies and technological means in the investigation of crimes are considered. It is noted that one of the main directions of the development of Criminalistics is the assimilation of the virtual reality associated with computerization of spheres of life, implementation of modern technologies and their use in law enforcement. Technology use of laser scanning of terrain and objects resulting in 3D model is produced allows several times to increase informative value of data collected at the incident scene, provides a visual and convenient visualization in three-dimensional form. As against photo and video images, 3D model has a stereoscopic image and the ability to freely change the angle while viewing. Besides to scanning results can be stored on any digital media without the possibility of changes or adjustments. Attention is focused on the technological capabilities of 3D-visualization systems on examples of their use in foreign countries as technological means of capturing the situation of the scene and the subsequent of a crime reconstruction. Thus, using a portable three-dimensional imaging system for working with volumetric traces at a crime scene, it is possible to obtain accurate three-dimensional images of traces of protectors or footprints (shoes) on soil and snow. This system is an alternative to traditional methods of fixing evidence: photofixing and making plaster casts. Unlike other systems, new approach does not require the use of lasers. The expediency of expanding the range of 3D laser scanning system use in modern investigative and judicial practice of our state with the aim of increasing the level of provision of pre-trial investigation authorities with technological means and bringing it closer to European standards is argued.
