Assessment of the vertical accuracy of SRTM-1" data over the territory of Poland using the runway method

DOI: http://dx.doi.org/10.15576/GLL/2017.3.7

[download]

The aim of this project was to estimate the accuracy of the Shuttle Radar Topography Mission (SRTM) digital elevation model over the territory of the Republic of Poland, using the centreline
cross-sections of runways as reference data. This method is known as the runway method. The statistical investigations were carried out based on the height differences between the SRTM and the reference data. For this purpose, 22 sections of the SRTM with 1 arcsecond of spatial resolution (SRTM-1") and profiles of 30 runways were used. Data processing was performed using ArcGIS (Esri) software package. The study found that the SRTM-1" had a .3.65 m magnitude elevation bias. The standard deviation and root-mean-square error (RMSE) of the elevation differences between the SRTM and the reference data reached the level of 1.88 m and 4.14 m, respectively. The obtained results are consistent with the investigations of the SRTM-3" model conducted by other authors for the area of Poland and other countries. Overall, it can be confirmed that the SRTM-3" model performs significantly better over flat areas than the SRTM-1" in terms of RMSE of the vertical accuracy.

Impact of the mIstakes in the land and buIldIngs regIstry on real estate transactIons

DOI: http://dx.doi.org/10.15576/GLL/2017.3.21

[download]

Land and buildings record is a public register of figures and descriptive data containing information about the real estate properties, their owners or people who manage those properties. One of the many tasks of the district governor is to keep the registers of land, as well as the periodic verification of the registry data. The purpose of the article is to present examples of mistakes that occurred when making changes to cadastral data, the analysis of these mistakes, and the impact thereof on real estate transactions. The stages of creating a unified land cadastre as well as land cadastre history on Polish territory during the partitions will be explored.

Analysis of the distribution and density of measurement points in terms of terrain modelling

DOI: http://dx.doi.org/10.15576/GLL/2017.3.35

For the implementation of direct measurements, proper understanding of the existing relationships and spatial variability, and at later stages, for obtaining reliable results of geostatistical
analysis, adequate planning network measurement and correct placement of, and/or the evaluation of the number of measurement points in the measurement network are not the only necessary conditions. Another key prerequisite is choosing the right model for creating a DTM, which depends on the shape of the terrain. Correct spatial sampling should provide much information on the spatial distribution of the studied variable in an area, at minimal cost and with minimal effort. Faithful reproduction of the land surface that reflects any of the characteristics of the environment is not possible through DTM, due to a number of restrictions, manifesting themselves in the form and size of the data set; due to time and economic constraints; and also because the full complexity of the terrain’s surface cannot be measured or expressed. The present work undertakes to analyse the density and distribution of measuring points on four areas that have specific characteristics in common, yet they remain different in terms of surfaces, height differences, as well as their complexity. After selecting the research areas, these were designed and laid out in a grid with the shape of rectangles that were similar in structure to the GRID model. The data were analysed using geostatistical interpolation by ordinary kriging, in order to conduct a proper analysis of the distribution and density of the measuring points, to calculate the surface properties of a particular point, and in order to attempt to reduce the workload and cost factor.

Clusters constitute an organizational and economic phenomenon. Today, they are created in nearly all sectors of the economy, including production industry, services, and high technology
industries. Act of 20 February 2015 on Renewable Energy Sources (RES Act, 2015) introduced the term “energy cluster”. In the present article, we attempt to answer the question of how the energy cluster can pursue, on a local level, the goal of ensuring energy security, while respecting the requirements of environmental sustainability.

The promotion of renewable energy is an essential part of EU energy policy, and it significantly contributes to the implementation of the Energy Union Framework strategy. With a 17% share
in final energy consumption in 2015, the EU and the vast majority of Member States are well on track in terms of renewable energy deployment. The proposal for an energy cluster based policy, together with the energy clusters pilot packages, now under examination, aims to tackle the barriers limiting further local renewable energy growth.

Method for determining the focal length in a digital non-metric camera

DOI: http://dx.doi.org/10.15576/GLL/2017.3.71

[download]

The authors analysed the methods for determining the focal length in digital cameras (DC) and proposed a method, according to which the control-measuring grid (CMG) is located vertically
at a distance from the DC and a photograph of the CMG is made, then the latter (the CMG) is moved along the optical axis of the digital camera to the distance, which is fixed with a micrometre screw and, repeatedly, a series of photographs of the CMG is taken. After that, on the received digital images, the coordinates are measured on the corresponding intersections of the CMG, and subsequently, the focal length for the DC is determined. The a priori estimation of accuracy of determining the focal length for the DC by the proposed method is calculated. For approbation of the method, the focal length in the following cameras was determined: Canon EOS 350D, Canon EOS 450D, Canon EOS 5D.

Selected methods for improving photointerpretation features of ultrasonographic images with the practical application of wavelet transformation

DOI: http://dx.doi.org/10.15576/GLL/2017.3.83

[download]

Images of different sections of the examined tissue, and in the result, the spatial image of the examined organ on the flat screen of the monitor, are obtained using the mobile apparatus head, which is moved by the physician over the patient’s body surface. The obtained image exactly reproduces the reality, but its interpretation always depends on the physician. Only the proficient knowledge of anatomy enables the correct interpretation of the image. For example, a cyst looks like a homogeneous dark spot with regular shape and smooth edges, while the tumour has a heterogeneous structure, visible as different shades of grey and ragged edges. Of course, the interpretation of the image is not always as simple as that, and therefore, among the professionals it is considered, that good diagnostics is more important than even the most modern equipment. However, the technology and methodology of processing and visualization of images is not without significance. By using the wavelet filtration to transform original images – their photointerpretation becomes easier, and more accurate.

DOI:http://dx.doi.org/10.15576/GLL/2017.3.89

[download]

The aim of the research presented in this paper was to determine the precise location of drop zones that were used for parachute jumps of the ‘Silent and Unseen’ paratroops (Polish: Cichociemni) and for delivering military equipment during World War II. The studies were based on historical research containing information about the locations of the jumps and their schematic arrangement, Ordnance Survey Maps of the pre-war period, and a GIS system with contemporary geographic digital maps. Within the work, the available information about the drop zone locations of the period from February 1941 to December 1944 is summarized. Moreover, the calibration of available schematic maps is presented, based on contemporary digital data. The final part of the study contains an estimation of drop zone location errors compared against military tactical maps.

The scope of survey necessary to identify water-related hazards in rural areas

DOI:http://dx.doi.org/10.15576/GLL/2017.3.107

Broadly understood agricultural-arrangement works are a tool for the implementation of multifunctional rural areas development. These works are defined as a set of integrated technical,
organizational and legal procedures, taking into account the natural, economic, legal and social conditions, aimed at adapting the spatial structure of the area to the needs of its sustainable development, including new organization of agricultural production space. These may be activities in the field of water resources management, the purpose of which is to minimize the occurrence of extreme water-related phenomena – droughts and floods. However, it should be emphasized that these works are multidimensional. In addition to their positive impact on water resources, they create favourable conditions for the development of biological diversity, maintaining cultural landscape or limiting pollution to water. However, such activities may be properly planned and carried out in the course of the agricultural-arrangement works only when it is possible to identify and determine the elements that affect the circulation of water in rural space.
