The purpose of this study was to verify the applicability of unmanned aerial vehicles (UAVs) to update cadastral records in areas affected by landslides. Its authors intended to compare the accuracy of coordinates determined using different UAV data processing methods for points which form the framework of a cadastral database, and to find out whether products obtained as a result of such UAV data processing are sufficient to define the extent of changes in the cadastral objects. To achieve this, an experiment was designed to take place at the site of a landslide. The entire photogrammetry mission was planned to cover an area of more than 70 ha. Given the steep grade of the site, the UAV was flown over each line at a different, individually preset altitude, such as to ensure consistent mean shooting distance (height above ground level), and thus, appropriate ground sample distance (GSD; pixel size). The results were analyzed in four variants, differing from each other in terms of the number of control points used and the method of their measurement. This allowed identification of the factors that affect surveying accuracy and the indication of the cadastral data updatable based on an UAV photogrammetric survey.

The paper concerns spatial planning in Poland and its connection with the cadastre. The Polish spatial planning system defines the set of colours, lines, hatches, etc. destined for the preparations of spatial plans, though this has so far not been followed by a spatial planning model or application schema. The aim of this paper is to create a preliminary concept of the unified modelling language (UML) schema of database integrating 3D cadastre and 3D spatial planning. The authors initially define five unified modelling language classes representing spatial planning objects (four representing spatial objects and one a dictionary list). As spatial planning and cadastres are very strongly connected, these classes are implemented into a cadastral model that had been earlier enriched with 3D classes. The final results of this research are UML diagrams based on the Polish cadastral model as defined earlier in legal regulations. They comprise original cadastral model classes, 3D cadastral objects added in earlier research work, classes representing spatial planning objects and the relationships among them. Such a solution better connects cadastre and spatial planning on a structural level and introduces 3D elements into spatial planning which has basically been done in two dimensions.

Road transport is one among the sources of air pollution in a city, which results in lowering the comfort of life and increases the occurrence of respiratory diseases. The level of pollutants emitted in the city is variable, and it depends on the type and nature of the source and the manner of land development. For this reason, the purpose of the article is an attempt at a spatial (inner) diversification of a city in terms of air quality, using a study of perception and semantic differentials (SD). The research, which covered the period from June to November 2021, was performed in Kielce—the Polish Smart City—among local experts, people well acquainted with the city and knowledgeable about air quality and the impact of pollution on human health. The results allowed the demarcation of areas with the best and the worst parameters in terms of air quality within the city. Verification of the survey was carried out using the ADMS-Roads (Atmospheric Dispersion Modeling System) software for modeling pollution levels and GIS software, using data on road traffic. The verification allowed checking whether the respondents participating in the research accurately evaluated the city space. The modeling proved that within the two selected areas, the pollution level is similar, and it does not exceed the permitted values. This might indicate that in society there is still low awareness of air quality, particularly in terms of knowing the sources of pollutants and their impact on human health, and perception of areas with the best and the worst air quality was the result of an analysis of the manner of land development and its morphology.

The main goal of the paper is to make a general assessment of the application of 3D technologies in spatial planning. It was performed with the city of Krakow as the case study. The paper describes the outline of the spatial planning system in Poland and the planning conditions of Krakow. The data obtained from laser scanning for Krakow are also briefly characterized. The possibility of using these data for locating high-rise buildings in terms of the protection of Krakow’s panorama and within two programs “IT system of the Country’s Protection Against Extreme Hazards” (ISOK) and “Integrated spatial data monitoring system for air quality improvement in Krakow” (MONIT-AIR) were analyzed in the paper. The main result of the research is the assessment of what studies or measurements may be used to meet particular spatial planning needs or requirements.

Spatial planning is an extremely powerful tool, which can be used for shaping the development of the largest spaces, including maritime space. In order to improve maritime management, the European Union decided to establish a framework in the form of a Directive to support planning processes in these areas. The result of the EU legislation will be land use plans, which will organize human activities in maritime areas in such a way as to meet environmental, economic and social objectives. The EU law applies to the Baltic Sea, Black Sea, Mediterranean Sea and the North-East Atlantic. However, since the internal regulations of individual EU countries differ from one another, the Polish part of the Baltic Sea was selected as an example. The conducted considerations include an analysis of the legal provisions that are to lead to the preparation of the above-mentioned plans. The research material includes both the provisions of the international and of the national laws. For the evaluation of the maritime spatial planning system, which is based on the above-mentioned research material, the SWOT/TOWS analysis has been used. This technique has been aimed at determining the directions of development of maritime spatial planning in Poland based on the current conditions of the spatial planning procedure for these areas as well as the future phenomena related to the implemented procedure for creating maritime area land use plans. It has been pointed out that maritime spatial planning should be carried out using the strengths of the current procedure and the external opportunities that would increase the importance of Polish maritime areas.

This research aimed to use the cause-and-effect diagram (model) as a method to describe the 15 main factors (for example, awareness, knowledge and motivation of farmers, farmers income, institutional and financial support, condition of the natural environment, healthiness of the population, etc.) leading to soil acidification, their impact on soil health and ecosystem functions, and how soil liming serves as a remedial measure. The cause-and-effect model was developed based on questionnaire studies as a part of the project ‘Opportunities and Barriers to the Use of Soil Liming for Improving the Economic Efficiency of Agricultural Production and Reducing Eutrophication of Surface Waters’ in 2022–2023. The results showed that the effects of soil acidification and liming as well as their interrelationships are multifaceted and affect agricultural production economics, agricultural land and crop prices, environmental health and biodiversity, as well as soil productivity and food security. The causes of this situation can be attributed to social, technological–logistical–technical, and economic factors. To change the existing situation, it is necessary to take effective steps to motivate farmers to lime their soils. The most effective would be (1) offering training courses for farmers to discuss the benefits that a farmer can achieve by maintaining optimum soil pH levels while growing a specific crop species; (2) implementing liming payment programs that will be more attractive and motivating from the farmers’ perspective; and (3) linking agri-environmental payments to the necessity of systematic testing of soil pH levels and maintaining optimal pH levels under specific crops species.
