- Cartographic sources as a base of knowledge about land use in selected
areas in the north-western Poland
Abstract: The aim of the research was to analyse land use changes and to develop a coherent base on the basis of available cartographic source materials – archival and contemporary topographic maps and spatial databases. The presented research is a continuation of works related to the cartographic visualization of changes in the distribution of the settlement network in the Noteć Forest – one of the largest forest complexes in Poland. The analysis was performed for nine villages together with their immediate surroundings, located in this area. The total surface area of lands covered by the study was 32,468 km2. Cartographic source materials were collected for selected areas. The archival maps were georeferenced and then digitized. In this way, the data has been transformed into a homogeneous system enabling further comparisons and analyses in an automated manner. Geodetic software (C-Geo), GIS (MapInfo, QGIS) and GNSS technology were used in the work. Cartographic sources can be successfully used for spatial analyses and environmental studies, providing reliable and available quantitative data. This type of research is important because it shows the changes taking place in the natural environment and can be used in works related to spatial planning, landscape ecology and social research.

- The Orthophotomap of Lublin 1944: from photographs to map application –
idea, methods, contemporary challenges of processing and publishing
archival aerial photographs
Abstract: The origins of aerial photography can be traced back to the second half of the 19th century, and periods of World Wars contributed to the development of techniques for developing and disseminating aerial photographs for military purposes. In the literature, we find descriptions of the Polish Military Geographical Institute’s (WIG) use of aerial photography to update topographic maps of nearly 40% of the country’s area at the time. Unfortunately, the fate of the pre-war collection of photographs is difficult to establish. Given this, the aerial photographs from the period of the Second World War (German and Allied) constitute the oldest possible complete and consistent photographic documentation of Poland. The series of German prints (373-GXPRINTS) collected at the National Archives and Records Administration in College Park (NARA, USA) are maintained according to the most liberal policy on access and further use. At the same time, the organisation of the NARA archive and the extent to which the collection has been digitised (over one million images) leave a deficiency, and searching for images requires knowledge, methods and experience.In 2020–2021, the Department of Geomatics and Cartography of the Maria Curie-Skłodowska University implemented the project Development of the Ortophotomap of Lublin 1939–1945 (NCN, Miniatura 4.0. No. 2020/04/X/HS4/00382). The result of the project is a dedicated web portal https://ortolub.umcs.pl, consisting of a digital repository of aerial images, a map application and standardised GIS raster data services. The author believes this is a unique source base, with unprecedented detail. The publication of the project results under the Creative Commons CC-BY-SA 4.0 licence is intended to foster the widest possible use of wartime aerial images in scientific research and popularisation activities.The process of developing a historical orthophotomap, as presented in the article, is universal and can be repeated on any set of aerial photographs. At the same time, development work is needed to automate the operations as fully as possible. In conclusion, current challenges and prospects for the development of historical orthophotomaps of national coverage are indicated.

- Developing a simulator of a mobile indoor navigation application as a tool
for cartographic research
Abstract: Solutions designed for indoor navigation are extremely rare compared to outdoor navigation; however, the potential for development is, therefore, very high. Several pilot projects exist in airports, universities, hospitals, and shopping centres. The difficulties in development are currently mainly due to the continuing low quality of indoor positioning and lack of widespread access to high-quality building models. A strong methodological basis for how the interior and exterior of buildings can be cartographically represented in navigation applications has also not yet been developed. Therefore, an attempt was made to design a virtual environment dedicated to supporting the design of indoor navigation applications.
Authors present the results of a study aimed at creating a concept of a simulation environment accompanied by the assessment and preliminary validation of its technological feasibility in terms of the method and technology used – although it does not yet constitute a target study. The result was a fully functional prototype of a virtual test environment, which was successfully used in a pilot study on the effectiveness of different types of navigation guidance. The participants’ behaviour within the desktop virtual environment was investigated and their opinions were collected through a questionnaire. This research proved the technological feasibility of the proposed concept and demonstrated the usefulness of the Unreal Engine game engine in building new tools to support the work of cartographers. The created environment will be further developed and used in indoor mapping research.

- Plan of Kalisz by Andrzej Politalski from 1785 – a source edition in the
Polish Historic Towns Atlas
Abstract: The plan of Kalisz by Andrzej Politalski is the oldest geometrically accurate depiction of the town. Compiled in 1785, it has survived to this day in a redrawing by Ottomar Wolle in 1878 at the scale of 1:3,000. The author discusses the process of developing the edition of Politalski’s plan for the “Kalisz” volume of the Historic Towns Atlas (HTA) and compares it with editions in other volumes. The most recent (2021) volumes developed in three different centres were chosen as comparative material: Biecz volume (Kraków); Fordon, 2nd edition (Toruń); and Racibórz (Wrocław). Each volume adopts different editorial rules, although, in general, they conform to the overarching principles of redrawing a map at the scale of 1:2,500. The differences touch on virtually all aspects (source material, scope of content, non-cartographic elements), but they are united by the aforementioned common scale and purpose. Developing the edition of Politalski’s plan was preceded by genetic analysis and the identification of filiation of its remaining copies. The original (1785) has not survived, nor has the first redrawing (1800). We only have a redrawing by Wolle (1878), which was the basis for the development of the plan for the HTA. In addition to this, we also have several other less significant versions. Politalski’s plan was georeferenced, its content was vectorised, and cartographical representation was created. The result has been put together with selected editions elaborated to date. A distinctive feature of the work on the “Kalisz” volume is the use of a redrawing of the original as a source plan, as it is – in fact – its historical edition. The author also draws attention to the issues of standardisation of data models and, consequently, of legends between particular volumes.

- Maps from (1750): a listing of plates and states
Abstract: The paper sets out to attempt identification of all known plates used to print maps included in the Atlas Silesiae and of all identified states of these maps. While the early states of the Atlas maps are relatively well studied (though far not in every detail), printings pulled from the same though deeply reworked plates, published in Nurnberg in the first two decades of the 19th c., are not always recognised as the late states of the same maps. For each of twenty maps from Atlas Silesiae listed are all identified states together with the most distinctive differences between them. Eleven copies of Atlas Silesiae were also examined in search for possible regularities of their composition in terms of states of the included maps. Public collections with exemplary copies of the Atlas maps in each state identified in the paper are listed in the Appendix.

- Verifying and improving map specifications of river network selection for
automatic generalization of small-scale maps
Abstract: Automated generalization is highly desired for effective map production. This research focuses on the initial stage of generalization, namely object selection. The study aims to conduct river network automatic selection based on map specifications contained in the Minister of Internal Affairs and Administration regulation. The research covers river network selection from the General Geographic Objects Database from 1:250,000 to 1:500,000 detail level. Within the research scope, three selection variants were designed. The first was a basic variant that only included the implementation of the specifications contained in the regulation. The other two were experimental variants: an extended variant and an extended-modified variant with the parameters and data enrichment proposed by the authors. The extended variant has been supplemented with the Id_MPHP index usage, derived from the Map of Hydrographic Division of Poland (MPHP), which defines the hierarchy of watercourses in the river network. The extended-modified variant was implemented according to the guidelines of the regulation, with the use of the Id_MPHP index and additionally with the help of the parameter denoting “priority” watercourses, which was assigned by the authors. The results of the work constitute the generalization models designed in ArcMap 10.8. with the use of Model Builder functionality as well as the maps presenting the selection variants output visualizations. The results were compared visually as well as verified with the reference atlas map generalized by an experienced cartographer. As a result, the map specifications concerning the selection process presented in the regulation proved to be insufficient to generalize river networks properly. The variants proposed in this research made it possible to improve the selection results and enabled the automation of the river selection process. Additional specifications and parameters proposed in this work may constitute an essential supplement to the guidelines contained in the regulation.

- Conformal projections of a tri-axial ellipsoid based on isometric
coordinates: history, methodology, and examples
Abstract: The paper presents a review of the conformal projections of a tri-axial ellipsoid and the methodology of creating these projections with the use of isometric coordinates. The concept is very simple and has been known for a long time; if isometric coordinates are introduced on the surface of the original and on the plane of the image, then any analytical function of the complex variable, i.e. a function that has a continuous derivative, creates a conformal projection. The introduction presents the history of conformal projections. Then, existing projections are presented, including the Bugayevskiy projection and several projections developed by the author that apply selected functions of the complex variable. Scripts were prepared in the Octave software with the use of the presented methodology. Programming in Octave offers a possibility of a simple implementation of complex variable functions, which is also briefly discussed in the paper. The developed scripts were then used to perform calculations and to draw cartographic grids and distortion isolines in the selected conformal projections. The test object was the tri-axial ellipsoid that represents Phobos.

- Do navigation maps need a legend' Empirical assessment of the
intuitiveness of point symbols on mobile maps
Abstract: Navigation applications and the mobile maps that are integral to them are now widely used all over the world. The most popular applications of this type, such as Google Maps, has more than a billion users a month. To save time, users of navigation applications generally use the maps without referring to their legends, which are not shown in the default settings. In such circumstances, only intuitive symbols are read correctly. Mobile maps often have an extensive system of point symbols (POIs – points of interests), and navigation applications sometimes differ significantly in the symbols they use. Point symbols have been the subject of theoretical considerations and empirical studies of users, but there is a lack of comparative research indicating more and less effective solutions for designing intuitive symbols on mobile maps. This article presents the results of empirical research on the intuitiveness of POI symbols used in selected navigation applications. The study was conducted in the form of a questionnaire with 127 respondents. The results confirmed the hypothesis that the analysed symbols used in navigation applications would differ in level of intuitiveness. In addition, features of design solutions that increase or decrease the intuitiveness of point symbols were identified.

- Analysis of the possibility of using key-value store NoSQL databases for
IFC data processing in the BIM-GIS integration process
Abstract: The article discusses the possibility of using Redis key-value NoSQL database to process building data in different BIM-GIS integration solutions. Whichever data integration model is adopted, it will require an efficient serving of building data in Industry Foundation Classes (IFC) format. The author proposed a method of processing building data in the Redis database to support the process of feeding IFC data to his own concept of an integrated BIM-GIS database. However, other approaches to BIM-GIS integration, including the import of IFC data to CityGML, or the construction of an integrated BIM-GIS solution based on data integration at the application server level or client application in client-server environments, also require an efficient IFC data serving mechanism. This article describes three methods of storing IFC data in a Redis database using different data types and formats. The author conducted performance tests of the proposed methods in the processing of fourteen test BIM models. The article contains detailed results of the model processing tests in the Redis database.

- Algorithm of automatic digital cartographic generalisation with the use of
contractive self-mapping
Abstract: The research of modern cartography in the field of digital generalisation focuses on the development of such methods that would be fully automatic and give an unambiguously objective result. Devising them requires specific standards as well as unique and verifiable algorithms. In metric space, a proposal for such a method, based on contractive mapping, the Lipschitz and Cauchy conditions and the Banach theorem, using the Salishchev metric, was presented in the publication (Barańska et al., 2021). The method formulated there is dedicated to linear objects (polylines). The current work is a practical supplement to it. It presents the practical implementation of the algorithm for automatic and objective generalisation. The article describes an operational diagram of the subsequent stages of the proposed generalisation method. In the test example, a binary tree structure of an ordered polyline was created. It was simplified in two selected scales and its shape after generalisation was illustrated. The resulting polyline obtained by the fully automatic method was verified in terms of accuracy.

- Using different mapping techniques and GIS programs in the analysis and
visualisation of mental maps
Abstract: The paper presents the review of mapping techniques applied in research using mental maps. The review covers both evaluative and structural mapping. The choice of a method is influenced by the level of freedom given to the respondents while creating sketch maps. It is also highly affected by the area of a given region, scale used in the research and limitations of mapping techniques in GIS software. For large scale maps created in GIS software, it is possible to use quantitative methods, i.e. proportional symbol maps or quantitative signature symbols. Using multiple complementary mapping techniques allows to draw the most comprehensive conclusions in the analyses of perception of a given space in the society.

- Status of the cartographic model
Abstract: The author presents the proposal for a map as a model based on the current concepts in the philosophy of science. It is the attempt to define a map within the general theory of the model – in its ontological, semantical, and epistemological aspect. Treating a map as a model of reality boils down to specifying several characteristics determining its character. The article primarily aims at broadening the discussion on what a map is and what defines it as a model of reality. A new definition has been proposed in effect of the deliberations based on the analysis of models’ typology in the sphere of philosophy.

- Development of metadata for historical cartographic resources associated
with the Paris Peace Conference (1919−1920)
Abstract: In the era of interdisciplinary research supported by IT solutions, a special role is played by digital source repositories. The digital turn has contributed to their considerable development, and the application of new technologies has largely changed the current methods of research work. This facilitates pooling and structuring dispersed collections e.g. as part of thematic repositories, which collect and share thematically related resources. Metadata, which allow effective searching and identification of resources, are an important element of their function. The objective of the article is to present a procedure for the development of metadata aimed at creation of a thematic database of dispersed sources remaining after the Paris Peace Conference ending World War I. Based on the metadata development procedure, the author discusses the diagnosed problems associated with e.g. the specificity of the analyzed sources.

- Determination and evaluation of spatio-temporal trends on the example of
PM10 concentration in Poland (2000−2018)
Abstract: Increasing amounts of rapidly growing data are the driving force behind proposing and automating new processing, enabling the extraction of useful information from data. One of such possibilities is determining trends to consider in terms of time and space. Thus far, the analysis of these aspects has been separate and lacked automated tools. Therefore, the authors proposed, implemented, and tested a tool for analyzing spatio-temporal linear trends. The tool was tested on PM10 concentration data in the years 2000–2018. The results, presented as cartographic visualization, were then evaluated, both in terms of time and space. The proposed approach facilitates analyzing spatio-temporal trends and assessing their accuracy; it can be developed using other types of analyzed trends or considering additional factors that influence the trend by using cokriging.

- Cartographic visualization of density: exploring the opportunities and
constraints of Heat Maps
Abstract: The authors of the review aim to understand and assess cartographic Heat Maps’ (HM) designs, tools, and applications. The paper consists of two parts. First describes HM in the context of neocartography and map design by tackling such issues as definition, input data, methods of density determination and generalization, colour schemes, legend construction, and base maps. The second part assesses the range of 17 tools used for creating HM. Tools are divided into non-GIS tools (visualization tools and programming libraries) and GIS applications (desktop and webGIS). GIS desktop software has been selected due to its popularity and wide application. Paper presents an expert assessment of this software with the use of a research questionnaire. The analysis made it possible to develop a division of tools based on their embedding in computer programs and applications and taking into account the types of visualization. It also made it possible to indicate tools that can be used by both professional GIS users (e.g. analysts, cartographers) and the general public, including teachers using HM to visualize geo data for geography lessons. The limitation of the review was the analysis from the expert’s point of view. It would be desirable to include novices perspectives in future studies due to the wide demand for visualization.

- The method for the quality evaluation of open geospatial data for creation
and updating of datasets for National Spatial Data Infrastructure in
Ukraine
Abstract: The purpose of the article is to present the research on method of the quality evaluation of published open geospatial data and its implementation in Ukraine. The method of the quality evaluation of open geospatial data considers the international standard ISO 19157 “Geographic information. Data quality”. This method is to determine the number of points or levels (maximum – 5). The research was carried out for the evaluation of open geoinformation resources for production of geospatial datasets, as defined in the Ukrainian Law on NSDI. The authors evaluated the quality of 142 open geoinformation resources and other information resources (materials) for the production and updating of 34 geospatial datasets for the development of NSDI in Ukraine. The authors present the example of the quality evaluation of geospatial data for datasets: “State Geodetic Reference Coordinate System UCS-2000”, “State Geodetic Network”, “Geographical Names” and “Administrative Units” because they are the components of the Core Reference Dataset of NSDI. Limitations of the research were determined by the adopted the Law of Ukraine “On National Spatial Data Infrastructure” and the Order for NSDI functioning in Ukraine and the requirements of the international standard ISO 19157 “Geographic information. Data quality”. The results of the research will be employed to evaluate the quality of NSDI implementation in Ukraine. The proposed method allows evaluating the quality of open geospatial dataset before using them for analysis and modeling of terrain, phenomena. This method takes into account the quality of geospatial data, and its related requirements for their production, updating and publication.

- Contemporary status of topographic mapping in Ukraine
Abstract: The fundamentals and contemporary status of topographic mapping of Ukraine’s territory has been studied. Prior to declaration of Ukraine’s independence, its territory was covered with 1:10,000 to 1:1,000,000 scale topographic maps made by sub-divisions of the Chief Department of Geodesy and Cartography affiliated with the Council of Ministers of the USSR (GUGK USSR) and sub-divisions of the Military Topographic Service (MTS) of the USSR Armed Forces. Topographic mapping related cooperation between these institutions has been described. Topographic study of Ukraine’s territory as at 1991 has been subject to close analysis, with due consideration of the coordinate systems used for topographic maps.During the first years after Ukraine’s independence declaration topographic maps in Ukraine were made according to the previously effective Soviet instructions in the 1942 coordinate systems and 1977 Baltic height system. Since mid 1990s, Ukraine enjoyed transition from analog technology of making topographic maps to digital one. The contemporary legal and statutory support of topographic mapping in Ukraine has been studied; the implementation since 1 January 2007 of the UCS-2000 national geodetic reference coordinate system and the height system measurement works have been analyzed. Focus has been made on obsolescence of information of contemporary topographic maps and on extensive deprivation of secrecy for topographic maps in 2000s.Critical for the development of topographic mapping in Ukraine is now the Law of Ukraine “On National Geospatial Data Infrastructure” adopted in 2020. The Topographic Service of the Armed Forces (TS AF) of Ukraine carried out big scopes of works to update the topographic maps related to Russia’s military operations against Ukraine.
