Method for creating digital orthophotomaps of increased informational value

DOI: 10.15576/GLL/2018.1.7
[download]

The paper discusses how to apply the information on the density of three-dimensional point cloud, obtained as a result of computer stereo reconstruction of an area, based on aerial images.
Images of high objects – particularly walls, treetops, bushes, etc. – in a particular area are used to create a point density map by means of GIS instruments. The information enables redistribution of the weight of cloud points in order to intensify or reduce their impact on the digital model of an area, or orthophotomap. The proposed method has been used to create orthophotomaps based on aerial images obtained from UAS.

Competitiveness of the respective districts of the Małopolska province in the social, economic, and environmental dimension

DOI: 10.15576/GLL/2018.1.19
[download]

The aim of the article was to present and examine the level of competitiveness of the districts (poviats) of Małopolska province, and compare them with each other in this respect. The analysis included three dimensions: social, economic, and environmental. This subdivision results from the direction of implementing the principles of sustainable development. In each dimension, typical variables have been selected, which facilitated the determination of respective competitive positions of each district. The study was based on a multivariate space of variables, using one of the methods of taxonomic classification – Ward’s agglomeration, and combinatorial operative method of enabling separation of homogeneous clusters in respect to the studied phenomenon. In order to determine similarities between individual units (districts called poviats, or counties), matrix of Euclidean distances was used. Analyses have shown that towns with district rights tend to enjoy high competitive positions, as well as those districts located in the southern part of the Małopolska province.

The process of map calibration and its impact on the quality and accuracy of cartographic materials

DOI: 10.15576/GLL/2018.1.33
[download]

The calibration process is a procedure that enables adjusting the scanned portion of the map to the current frame of reference, and equipping it with cartometric properties. As a result of the said process, the raster image becomes cartographic material that can be applied, among others, to the context of geodetic work. There are numerous methods of image transformation and ways of selecting the control points, according to which this process can be carried out. In the paper, the authors present the literature review featuring various problems related to the map calibration process, as well as the methods of transformation, and the ways of selecting the control points. The work was carried out in reference to the example of scanned fragments of cadastral maps, which were then subjected to calibration processes using crosses of map graticule lines and based on situational details. The calibration process was carried out several times using a different number of adaptation points while changing their location and the manner of selection.

Sources of spatial data in the process of 3D modeling of buildings in accordance with the CityGML standard

DOI: 10.15576/GLL/2018.1.45
[download]

3D models of buildings play an important part in spatial management. There are many sources of spatial data based on which 3D modelling is possible, but the selection of the most appropriate source should result from the level of detail of the 3D rendering that we are aiming for, and the intended purpose of using the resulting 3D model. The paper discusses the most important data sources – from the point of view of 3D rendering of buildings in accordance with the CityGML standard – and that includes: airborne and terrestrial laser scanning, aerial and ground photogrammetry, as well as vector data accumulated in the BDOT10k database.

Transformation of the former austrian cadastre map

DOI: 10.15576/GLL/2018.1.55
[download]

The aim of the present work is to show and compare the process of transforming the map of the former Austrian cadastre from the analogue format to the numerical version, in connection with its still valid application in geodetic-legal, urban design, and planning processes. These include, inter alia, litigation and court cases regarding the extent of ownership of real estate, work related to real estate management (divisions and demarcations), use of maps of former cadastral systems in the process of land consolidation, or modernization of land and building registers and creation of a digital cadastral map, as well as any research studies pertaining to the analysis of spatial changes in the natural environment. Within the defined scope of research, the following steps were taken: calculation of corner coordinates of the sectional frame, transformation of the obtained coordinates from the KUL system into the “2000” system, followed by calibration and raster vectorization. The calibration process was performed using three different computer software applications, which are used on a daily basis by surveying companies throughout Poland. Serving as the material for research, a cadastral map of the village of Strzelce Wielkie in the Szczurowa municipality was adopted, that had been acquired from the State Archives in Kraków.

Challenges to the development of rural areas in Poland

DOI: 10.15576/GLL/2018.1.69
[download]

Geodetic management of rural areas in Poland is currently experiencing a kind of decline, caused by the relatively limited range of land consolidation projects. At the same time, structural problems of farms and, much more broadly – of rural areas – are among the biggest development problems in Poland. Therefore, it is suggested that wide-ranging proceedings for the so-called comprehensive management of rural areas should be introduced to the practice of geodesy and to issues of agricultural areas, which would include broad measures enabling sustainable spatial and structural development of rural municipalities, and provide solutions to particular problems occurring locally. This concerns in particular the broad (comprehensive) activities involving the preparation and implementation of spatial and infrastructural transformations needed locally in order to preserve and improve the economic (including also agricultural), residential, natural, and cultural functions of these areas, which would be intended to support the sustainable improvement of working and living conditions in the countryside.
