The subject of the research in this paper was a review and identification of types of cartographic documentation used in crisis management in Poland. The analysis focused mainly on assessing the usefulness of cartographic data for visualising the scale of natural phenomena such as floods, landslides, droughts, wind, and others. The most important map that serves as a reference base for various types of industry-related works, especially derivative geodetic works, is the cadastral map stored in the resources of the Land and Building Register. In this study, the authors concentrate on the possibilities of using cartographic data, with a particular emphasis on cadastral maps, for crisis management purposes. The aim of this paper is to review and provide an expert assessment of the usefulness of cartographic data in emergency situations. The research shows that cartographic data are crucial for each of the mentioned hazards, especially the resources of the Land and Building Register, which allow the visualisation of the spatial and temporal scale of these hazards. The success of the measures taken to reduce the occurrence of floods or landslides, for instance, depends first and foremost on fast and seamless access to reliable and up-to-date information on the terrain. The cadastre is one of the publicly accessible registers providing this data, without which crisis management could not be fully effective. The study was conducted through an online survey using an interactive sheet, dedicated to experts (services dealing with different types of hazards).

DOI: http://dx.doi.org/10.15576/gll/2023.3.19
Development potential, studied on the example of the city of Nowy Targ, is defined by the authors as a set of factors contributing to social, economic, and environmental development. Development potential is also understood as a positive change. Properly examined, it provides an opportunity to maintain good practices, such as the protection of ecologically valuable areas or the preservation of traditions directly derived from the region’s characteristics. The methodology used in this study, based on the point bonitation method, has already been applied in the context of ecological and natural assessments of selected territorial units. This publication demonstrates the application of this method to the selection of variables, allowing us to determine the development potential using Nowy Targ as an example. The authors place several indicators in three research sectors: the city’s economy, natural environment, and social development. For the purpose of this study, the city area was divided into 245 squares (PPO) with sides of 500 m × 500 m. The size of the PPOs was chosen with regard to the purpose of the research and adapted to the city’s area. 15 diagnostic variables were adopted in the examination of Nowy Targ’s development potential. The conducted research resulted in a cartographic visualisation of the data using GIS tools. This research provides an opportunity to deepen the analysis of the appropriate choice of development directions when working on municipal development documents. An important advantage of the employed method is its flexibility. A weakness of this method lies in the subjective selection of variables by the researchers and the thematic scope of the chosen research problem. The resulting cartograms allow for a quick assessment of the areas influencing the city’s development or degradation.

The point location problem is one of the most fundamental topics in computational geometry. This problem is particularly well illustrated in the context of maps. In order to determine a point location, it is necessary to work in a specified space, with known division rules. A practical example can be a map sheet division system adopted for the International Map of the World. Given the current advancements in spatial data acquisition and growing availability of spatial data sets, it has become necessary to design an algorithm to identify a map sheet corresponding to a selected point. Available digital data, e.g. orthophotomaps or LiDAR-based data sets, cover whole countries. Due to the size of such data sets, they need to be divided into smaller chunks. The article presents a method of determining a map sheet identification number and a map sheet extent based on the latitude and longitude of a selected point. An inverse problem has also been addressed, allowing a map sheet extent to be identified based on a map sheet identification number. The algorithms developed might be directly implemented in GIS software. They are presented in a ready-to-implement form in the Basic programming language with the use of basic data structures.

DOI: http://dx.doi.org/10.15576/gll/2023.3.47
Map portals can facilitate the work of public administration units and improve access to information, although they have to present high material and technical quality. Not without significance are also measures supporting these websites. This paper aims to assess the quality of selected geoinformation websites. The study was carried out in the form of a quality audit with the use of selected web applications provided in a freeware, thin-client model. A comparative analysis was performed on three versions of the geoservice functioning for the Tomice municipality (accessed on 5th July 2023): 1) eMPZP website (https://www.tomice.pl/mpzp/), 2) municipal geoportal (http://www.mpzp.tomice.pl), and 3) municipal map portal (https://sip.gison.pl/tomice). The measurements were taken only once and in an ad hoc manner. The tests were performed in selected quality dimensions: responsiveness, performance, content and hyperlink quality, accessibility for people with disabilities, syntactic code correctness, search engine optimisation (SEO), and usage indicators, with special emphasis on overall quality. The conclusion was that each of the geoportals evaluated presents good quality. However, it would be wrong to compare them in absolute terms, as the quality of these services should be assessed through the lens of the different times in which they operate.

DOI: http://dx.doi.org/10.15576/gll/2023.3.61
The main objective of this study is to show which of the LST-NDVI and LST-NDBI relationships can determine the most accurate index that can be used as an indicator of the effects of urban heat islands in the municipality of Guelma, using Landsat data. 8 OLI/TIRS and the geographic information system. The application of the calculation formulas made it possible to extract the Land Surface Temperature (LST), Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built up Index (NDBI) of the municipality of Guelma for the four seasons of 2019. This calculation led to the determination of the relationship between all three indicators. The results obtained show a strong correlation between the LST and the NDBI for the four seasons of the year. They suggest that the NDBI is an accurate indicator of the heat island effect in Guelma. This indicator can serve as a tool for future urban planning by those in charge of this department. However, there is currently and urgent need to strengthen strategies for reducing the effects of urban heat islands in order to preserve the quality of urban life of the inhabitants and by setting up emergency programs.

DOI: http://dx.doi.org/10.15576/gll/2023.3.73
The Coniacian-Santonian series in the Aures Mountains of northeastern Algeria is characterized by marly-dominated sedimentation processes. This study aims to comprehensively investigate this series by combining lithostratigraphic and biostratigraphic data. The unique paleogeographic position of the Aures basin supports the co-occurrence of diverse paleontological contents in the Upper Cretaceous sediments. The methodology employed in this study includes a detailed bio-lithostratigraphic analysis to subdivide the Coniacian-Santonian series into two distinct sets. The first set comprises alternating marl-limestone units that exhibit a high fossil concentration from the Coniacian age, while the second set mainly consists of marly sediments corresponding to the Santonian age. The results obtained from this study highlight the geographical distribution of litho-biostratigraphic characteristics and reveal the presence of two formations. The lower formation is characterized by carbonated marls intercalated with limestone banks, containing fossils of Peroniceras (Tissotia tissoto) from the Coniacian age. Meanwhile, the upper formation is predominantly marly and indicates the Santonian age by displaying fossils of Palcenticeras polypsis. Furthermore, a biostratigraphic analysis focused on foraminifers allows for the subdivision of the Coniacian-Santonian series in the Aures Mountains into three distinct biozones. The first biozone corresponds to the lower Coniacian age and is identified by the presence of Dicarinella primitiva. The second biozone represents the middle to upper coniacian age and contains Dicarinella concavata fossils. Finally, the third biozone, belonging to the Santonian age, is marked by the occurrence of Dicarinella asymetrica. The boundary between the Coniacian and Santonian series in the Aures Mountains is characterized by the first appearance of Dicarinella asymetrica and Palcenticeras polypsis species. This multidisciplinary study provides valuable insights into the litho-biostratigraphic characteristics and geographical distribution of the Coniacian-Santonian series in the Aures Mountains. The findings make a significant contribution to a better understanding of sedimentary processes and the paleontological content within this region during the Upper Cretaceous period.

, Renata Giedych Evaluation of the effectiveness of planning tools in the protection of landscape values, on the example of the Wysowa Zdrój village

Landscape values are defined in the Polish nature protection law as the natural, cultural and visual values of a given area formed by the nature forces or human activity. Protection of landscape values is realized by the establishment of nature conservation categories with different conservation regimes. No less important instrument for the protection of landscape amenities is spatial planning. This is particularly important in areas exposed to urbanization pressures due to the attractiveness of the area for the development of residential and tourist functions. The aim of this study was to assess the effectiveness of different instruments for the protection of valuable landscape structures. The research was conducted in the Wysowa village, a health and tourist resort. The analysis showed that the most stable elements of the landscape structure are forests. The most vulnerable to irreversible changes are arable land and pastures. Despite many provisions regarding the preservation of scenic exposure, landforms, historical layout of fields and buildings, one can get the impression that activities in the field of preserving landscape values are not strictly followed. This is due to the fact that some of the analysed documents do not have the character of commonly binding laws. In the documents legally binding at the municipal level, the provisions relating to the need to preserve protection of scenic values are very general and lack detailed guidelines regarding the specific measures that should be applied. As a result, there is a considerable flexibility in land use changes, which reduces the protection of landscape values.

The city of Biskra is ranked the second city in Algeria with the highest traffic accident rate. There are multiple causes of accidents that derive from the diversity of traffic. In addition, its geographical location as a crossroads between the northeast and the south of Algeria is a major factor. Biskra is also considered a commercial and industrial city that receives daily large flows of travellers and merchandise.
Traffic accidents are a complex problems that is dealt with in several approaches. In this research, from a geographical point of view, we will contribute to improve the trajectory of intervention and evacuation. Therefore, this research paper aims to create a geodatabase including the road network with associated entities to carry out spatiotemporal analyses and evaluate the service area of health facilities in terms of the nearest path.
This paper uses GIS tools for evacuation to the public hospital employing a Network Analyst. This study may serve as a decision-making aid for the local authorities of this city in terms of evacuation and intervention in the event of a road accident. It provides real-time information on the location of the accident and the nearest path along with an estimated time.
The outputs of these analyses can determine a map of accessibility, which allows for training in order to improve the real-time evacuation. As a result, this approach will lead to the reduction of evacuation time by less than 10 minutes, and thus leading to a decrease in the number of fatalities.

The impact of land set-aside on the chemical and physical properties of the soil and the composition of vegetation species. Case study
Corresponding author
DOI: http://dx.doi.org/10.15576/gll/2023.3.121
The study aimed to evaluate the effect of soil use in the Młoszowa and Bolęcin villages on the species composition of the overgrown vegetation. Additionally, the study compared the chemical and physical properties of the soils that were not being used for agriculture. The soils of Młoszowa and Bolęcinvillages did not exceed the permissible concentrations of copper, lead, and zinc for agricultural land, as outlined by the national regulations in [Journal of Laws 2016]. In Młoszowa, the concentration of cadmium exceeded the limit values as per national regulations in [Journal of Laws 2016] for agriculturally utilised land (land group II-2) (<3 g · 10–3 · kg–1 DM). The set-aside of both villages consisted of species typical of ruderal areas, fresh grassland, and thermophilous species. The granulometric composition of the soils, mainly their silt and sand content, were the primary factors that impacted the species composition of the set-aside vegetation. Ruderal and thermophilous species were discovered in the set-aside areas, which are their natural habitats. The occurring ruderal plants typical of post-mining heaps and post-industrial areas, including hemicryptophytes, testify to the long-term process of fallowing and adaptation to the existing ecosystem with a predominance of the most common species.
