Heritage objects are affected by many factors that affect degradation over time and damage to historical sites. For this reason, it is necessary to carry out continuous monitoring using non-invasive techniques for Structural Health Monitoring and plan the conservation works. This article aims to present the results of a project that involved long-t...

Cultural heritage sites are exposed to several factors that cause their deterioration and degradation, namely moisture content. There are several destructive and non-destructive methods available to monitor moisture. However, destructive methods are avoided in cultural heritage to prevent surface damage, while non-destructive methods are limited to...

Geomonitoring and structural monitoring systems currently play a crucial role in comprehensive facility risk management-both at their implementation and subsequent maintenance. Especially in the dynamic development of BIM (Building Information Modelling/Management) technologies, such systems allow for precise and systemic management of building obj...

The use of low-cost, unmanned aerial vehicles (UAVs) has been growing in many sectors. Due to the sufficient accuracy of the products acquired from UAVs, this technology has also been applied in geodesy and remote sensing. It results from many factors: the low prices of UAVs and the availability of different sensors and software applications, which...

Sensitivity analysis is one aspect of the calculation process in displacement measurement. For this purpose, sensitivity measures are used in the form of minimal detectable displacements ( ), derived from the definition of minimal detectable bias ( ). Analyses were performed based on disturbing the parameter vector with the value (calculated from p...

Heritage sites are affected by many factors that cause degradation and decay over time, such as soil deformation, changes in weather conditions, or excess moisture, which can cause damages to historical sites. For this reason, restoration works are planned and carried out to preserve the object's existing condition, renovate and repair the damaged...

The Minimal Detectable Displacement (MDD) is an important measure of monitoring networks sensitivity to displacements. In addition to the accuracy criteria, it is used as a detectability criterion in the optimal design of such networks. The paper examines whether the MDD provides grounds for verifying the correctness of the confidence, and the sign...

Modern measurement technologies are commonly applied to monitor and preserve the cultural heritage as it is an integral part of modern societies. The Terrestrial Laser Scanning (TLS) method is one of the common technologies investigated by the researchers for accurate data acquisition and processing required for architectural documentation. In rece...

This paper presents changes in the range and thickness of glaciers in Antarctic Specially Protected Area (ASPA) No. 128 on King George Island in the period 1956–2015. The research indicates an intensification of the glacial retreat process over the last two decades, with the rate depending on the type of glacier front. In the period 2001–2015, the...

The development of measurement technologies allows for acquiring various data. The Terrestrial Laser Scanning (TLS) technology is frequently combined with classic geodetic measurements – tacheometry or levelling. This article presents a process of the diaphragm wall monitoring during excavation supported with a top-down method. The construction tec...

Nowadays, cultural heritage is an integral part of modern societies and it is necessary to preserve the tangible and intangible evidences of the past. Cultural heritage objects and sites are being devastated by natural causes and human acts. There are many existing techniques for structural health monitoring, but in the cultural heritage area, ther...

Cultural heritage objects are affected by a wide range of factors causing their deterioration and decay over time such as ground deformations, changes in hydrographic conditions, vibrations or excess of moisture, which can cause scratches and cracks formation in the case of historic buildings. The electromagnetic spectroscopy has been widely used f...

All countries around the world are blessed with particularly rich cultural heritage. Nowadays, many researchers are exploring different methods for documentation, management, and sustainability of cultural heritage. The aim of this article is to review the state-of-the-art documentation, management, and sustainability techniques in the field of cul...

The paper presents archaeological and architectural research in the Royal Castle in Warsaw where a combination of image- and range-based 3D acquisition was applied. The area examined included excavations situated inside the Tower and near its outer western wall. The work was carried out at various periods and in different weather conditions. As par...

The paper presents the ongoing project conducted by an interdisciplinary team at the Bieliński Palace in Otwock Wielki, near Warsaw (Poland). The main aim of the project is to document the architecture and architectural elements with the use of digital methods such as photogrammetry and 3D scanning, as well as investigating the construction phases...

Nowadays the 3D documentation created through image-based approach is commonly used in Cultural Heritage management and preservation. This type of documentation, such as orthoimages and Digital Surface Models, is a well-established technique in the documentation of historical sites, monuments, and objects. In this paper, we investigate the possibil...

This paper concerns the use of high-resolution images from a Hasselblad H6D - 100c middle format camera in the investigation of wall paintings. The presented investigation, proved the great potential of an image-based approach combined with the used camera for such documentation. The conducted analysis shows that the obtained accuracy allows not on...

Modern measurement technologies are commonly applied not only to monitor Cultural Heritage objects; they are also applied during archaeological excavation works, when it is important to quickly perform measurements. The paper presents multitemporal integration of different image-based (UAV, close-range digital images) and range-based technologies (...

In this paper the possibility of using the Xiaomi 4K action cameras as a low-cost sensor for the generation of high resolution documentation of architecture and architectural elements in the field of Cultural Heritage was analysed. For that purpose a series of images was acquired together with tachometric measurements to determine the ground contro...

A non-distorting network connection is a complex procedure consisting of a local network adjustment and a subsequent Helmert transformation into the connection points without changing the scale, i.e. isometry transformation. Since a joint adjustment model proposed for this connection in the earlier publication did not turn out sufficient to create...

At present, digital documentation recorded in the form of raster or vector files is the obligatory way of inventorying historical objects. Today, photogrammetry is becoming more and more popular and is becoming the standard of documentation in many projects involving the recording of all possible spatial data on landscape, architecture, or even sin...

Close range photogrammetry has great potential for development as a tool for architecture analysis, especially through the use of low-cost image acquisition tools. Low-cost sensors allow for the creation of reliable and accurate three-dimensional models of investigated objects, while the data collected in the course of the documentation can serve f...

Poa annua, an alien species reported from the Antarctic continent and many Antarctic and sub-Antarctic islands was accidentally introduced in the vicinity of the Polish Antarctic Station H. Arctowski. Recently the species has been found entering native plant communities. In almost 30 years it dispersed over 250 m from the site it was first observed...

This paper presents survey measurements carried out during the 39th Polish Antarctic Expedition to the Henryk Arctowski Polish Antarctic Station in March 2015. The measurements were used to create a map on a 1:500 scale and for 3D modelling of the station buildings and vicinity. The paper also presents the geodetic control network established aroun...
