Performing spatial analysis based on a correct multifunctional geographically oriented model in the domain of road accident is an important part of the overall transport system management. The aim of the paper is to demonstrate a methodology for using a digital road model, defining optimal parameters for building a road graph and georeferencing occurred events to determine a spatial autocorrelation index of road accidents, entirely using open data. To achieve this goal, the foundation of international standardization laid down in ISO 19100 - Geographic information is used in combination with the method for spatial autocorrelation, extended for a network, practically implemented through the capabilities of the Python programming language as an element of a Geoinformation system of road accidents. Open-source data from the OpenStreetMap geoportal were processed, as well as real archive data for 1,288 serious accidents on the territory of the city of Sofia, Bulgaria, and a spatial autocorrelation coefficient was calculated to determine the dependence or independence of the number of road accidents between individual areas with its accuracy and reliability. The result is the definition of a correct basis for carrying out spatial analysis with the laying of a foundation for the subsequent study of various factors and the definition of a complex of reasons, the establishment of which will lead to a reduction in traffic injuries.

This paper aims to investigate whether Apian could be the developer of his namesake map projections. Evidences suggest that these mappings should not have been named after Apian. The most likely inventor of the Apian I map projection is Amerigo Vespucci, and the Apian II projection was probably developed only 300 years later by Frangois Arago. Given that the case of Apian map projections is not a single example when the map projection is not named after its real inventor and the original authorship of more mappings might be questioned in the future, the cartographic community should revise, whether it is a good convention to name map projections after their supposed inventor.

Based on selected cartographic depictions of Korčula from the early modern age, the paper examines the geographical knowledge about that island at the time the maps were made. Special attention is directed to the hitherto unknown map of the island of Korčula from the second half of the 16th or the first half of the 17th century, which is kept in the Archivio di Stato di Venezia, given that it shows a very detailed escription of the island of Korčula, especially its western part. The objective of this paper, using the example of the island of Korčula, is to point out the importance of cartographic renderings as an important source of spatial data and to determine whether there was a gradual improvement in the quality of the displayed geographical content in accordance with the assumed development of geographical knowledge and cartographic techniques from the beginning of the 16th century to the end of the 18th century. On the basis of the selected cartographic depictions of the island of Korčula, the significance of the island of Korčula in maritime and geographic frameworks characterized by different political interests, primarily that of Venice, was confirmed. The diachronic series of early modern geographical maps and nautical charts points to the gradual development of geographical knowledge about the island of Korčula, as well as to the improvement of the quality of graphical visualization of the relevant spatial data about that Croatian island.

With the development of geospatial information science and technology and applications in numerous areas, cartography and geospatial information education is becoming increasingly more important in training graduates equipped with new capacities. Cartography and geospatial information education are crucial to cartography and geospatial information science, as a discipline and a profession. The contents have always gradually been changing, as well as corresponding effective approaches to deliver sustainable and resilient education. In the new normal era of post COVID-19, summaries and reflections on the progress of available practices and theories can support better design of effective and quality education. In this paper, the conference papers and abstracts on educational topics published in the last 10 International Cartography Conferences are used to trace the path that educators in cartography and geospatial information have gone through. Bibliometric analysis is conducted on educational topics, authors, and regions. A domain term knowledge map is drawn showing that the number of publications on education in the International Cartography Conferences has been increasing. The geographic distribution of authors is very concentrated, with authors from European countries contributing about 50% of the publications and those from the top ten countries contributing 60%. Works in many other regions are less reported. The research topics are mainly focused on undergraduate and graduate education in geographic information systems, secondary education, education atlas, learning theories, learning environmental design, online education, etc. Pedagogies and experience of distance learning and online education in the last 20 years have been well applied. However best practices of online and distance education are rarely reported to support effective new normal education in the context of COVID-19 pandemics. [ABSTRACT FROM AUTHOR]

In this paper a proposal is presented on how cartographers can ensure and/or enhance the trustworthiness of maps. Maps, like all other means of communication, are a result of many decisions. Many of those decisions allow for several options. Default, clear or good practices, guidelines or recommendations do not always exist for which option to choose. It is rather a characteristic of cartography that individual decisions can be made, especially on data preparation, selection, and design aspects. Because every map is a result of many decisions, trust in maps depends on those decisions being reasonable, not questioned, transparently accessible or underpinned by reliable decision makers (reliable in terms of their record as an institution, because of their reputation, because of their competence). The advent of easy-to-use map making software and data handling instruments put some of those decisions in the hands of "everyone", as well as in the hands of many who might have an interest in using maps as instruments of communicating a specific agenda. This is like other means of communication and has led to a rising discussion on "fake news", "fake media" and "fake maps", thus ultimately how we can trust the communicated information and how we can distinguish "fake" from 'trustworthy" maps. Therefore, in this paper a proposal is presented on how cartographers can ensure and/or enhance the trustworthiness of maps. This is done by introducing two concepts of "going deep", allowing for transparency of cartographic decisions and "going wide", allowing for contextualizing a given map by being able to access alternative maps of the same topic. This proposal adds to the existing attempts to contribute to an ethical framework for map making, such as the Locus Charter or the Code of Ethics of the British Cartographic Society.

Ocean maps are rarely in the scope of current studies on minimum-distortion map projections. This study aims to create an uninterrupted map projection to display planet Earth as the Blue Planet: the aspect of the projection is rotated into the middle of the water surface; favourable map distortions are optimized numerically across the World Ocean. The paper starts with a short overview of existing similar projections. In the next pages, the reader may find the detailed description on the development of the new mapping. The paper concludes with maps and distortion analysis in the proposed projection and thoughts about its potential usefulness. [ABSTRACT FROM AUTHOR]

Lambert (1 772) derived the equation of the Mercator projection as a limiting case of a conformal conic projection. In this paper, we give a derivation for equidistant, equal-area, conformal and perspective cylindrical projections as limiting cases of equidistant, equal-area, conformal and perspective conic projections. In this article the conic and cylindrical projections are not projections on a cone or a cylinder whose surfaces are cut and developed into a plane, but rather mappings of the sphere directly into the plane. Exceptions are projections that are defined as mappings on the surface of a cone or plane, as is the case with perspective projections. In the end, we prove that it is not always possible to obtain a corresponding cylindrical projection as a limiting case from a conic projection, as one might conclude at first glance. Therefore, the final conclusion is that it is not advisable to interpret cylindrical projections as limiting cases of conic projections. [ABSTRACT FROM AUTHOR]

Ghana is a country exceptionally rich in geologic mineral resources with contrasting topographic relief and varied geophysical setting. This paper evaluated the geological and geophysical setting of Ghana with a special focus on the impact of the geologic setting and topography on gravity. Specifically, it assessed how variations in geology, topography, landscapes and the environment control the geophysical parameters and how these vary among the major regions of the country - the Volta Basin, Northern Plains, Ashanti-Kwahu (Kumasi) and Coastal Plains in the Accra surroundings. Previous studies utilizing traditional Geographic Information System (GIS) approaches have documented the geologic evolution of Ghana evolved as a part of the West African Craton. As a contribution to the existing research, this paper presents a regional analysis of Ghana by integrated mapping of geology, geophysics and topography of the country. The technical approach of this research focuses on utilizing the console-based scripting cartographic toolset Generic Mapping Tools (GMT) integrated with QGIS for processing and mapping the datasets: General Bathymetric Chart of the Oceans (GEBCO), Earth Gravitational Model 2008 (EGM-2008), gravity grids. The theoretical background is based on the geologic research of West Africa supported by high-resolution data. The paper defines a conceptual cartographic framework for integrated geologic and geophysical visualization in a regionalscale mapping project on Ghana. [ABSTRACT FROM AUTHOR]

Mathematical elements of maps, in addition to the methods of presenting content with cartographic symbols and the criteria of cartographic generalization, are the most important elements of modern ground plan view maps. At the same time, on maps for orienteering disciplines, which are the most internationally unified maps in the world, the mathematical basis is not defined in very detailed specifications. In this paper, we describe the background and reasons for the apparent insignificance of mathematical content in orienteering maps, and on the example of the analysis of selected maps of Croatia and Slovenia, we determine in which period and to what extent mathematical elements were present on the maps.

The development of the State Border Geoinformation System of the Republic of Croatia (SBGiS), based on opensource technologies, has facilitated and accelerated the storage, processing, handling, analysis and visualization of large amounts of spatial data used in open border issues, as well as standard affairs on maintaining the regulated state border of the Republic of Croatia. Centralized data storage and their spatial visualization through an interactive map allows citizens to see the situation at the state border in real time, which significantly increases the safety of movement in the border zone, but also aids in the prevention of state border breaches. The SBGiS is the only system that has been established not only for maintaining a regulated state border but also for resolving border disputes and delimitation procedures. At the end of the paper, a proposal for future system upgrades is given. [ABSTRACT FROM AUTHOR]

Ethnic maps have regained importance and are again frequently published, due to an increase in ethnic consciousness, many ethnic conflicts and the attempts of young states particularly in eastern Europe to present themselves as nation states by ethnic maps. Questions of their methodology, of how suitable individual ethno-cartographic methods are to depict certain ethnic structures and whether they are applied correctly or not are therefore on the agenda of cartography as a formal science. This paper investigates the suitability of the main ethno-cartographic methods (areal method, dot spread method, diagram method) to render certain ethnic structures. [ABSTRACT FROM AUTHOR]

The map of Moravia (1569) by the renowned Vienna scholar, Paulus Fabricius (ca. 1528-1589), is still considered to be the oldest known cartographic representation of Moravia. This paper focuses on the cartographic analysis of the map with the aim to identify possible methods of its construction with regard to some known circumstances of its origin. The author of the map mentions in the appended texts that he travelled through Moravia several times. The methodology of the work is based on selected spatial analyses of the positional and height aspects of displayed settlements. The achieved results are compared and discussed in the context of other information sources, especially the existing settlement structure and contemporary communication network. The conclusions reveal a correlation between the density of the depicted settlements and the proximity of a modelled communication network. The orographic conditions of Moravia have a significant influence on the map content. The plains are covered in detail, hilly lands and highlands are rarely and randomly mapped, whereas the mountains are not described at all. In the peripheral parts of the area of interest, the author probably worked only with data from travel itineraries. With regard to achieved results, it can be assumed that there is potential to apply the established procedures to the analysis of old maps of similar type. Unlike later maps, they are based on the author's travelling experiences and impressions, rather than on complex measurements of geographical coordinates. [ABSTRACT FROM AUTHOR]

This paper aims to determine the landscape development trends of Central Lika and to analyze their interrelation with observed demographic inter-census changes. For this purpose, Landsat multispectral images and census data of the Croatian Bureau of Statistics were used for both observed years, and appropriate methods of analysis were selected. In the analysis of the satellite images, an approach was used that involves the use of data sets that are related to spring and autumn. Using the ENVI 4.7 computer programme, five classes were defined for each analyzed year: Built land, Forest, Water bodies, Arable land, Grass and shrubs, while five landscape development trends and their surface shares were identified based on their interrelation in the observed period (1 991 –2011 ): Unchanged (87.7 %), Extensification and vegetation succession (7.6 %), Intensification (2.8 %), Upbuilding (1.5 %), Water bodies (0.4 %). The obtained results showed that Upbuilding and Intensification are more represented in the central area, which is in line with the least negative demographic indicators, and with the process of urbanisation of the Town of Gospic. Extensification and vegetation succession is more prevalent in peripheral areas, where the most negative demographic indicators are more pronounced, which was found to be in line with the process of deruralisation and deagrarisation. By analyzing landscape development trends and the processes of the Central Lika landscape from different perspectives and aspects, this study allows for their better understanding.

The map named Carta Geographica deProjecçaõ Espherica Orthogonal da Nova Lusitania ou America Portugueza e Estado do Brazil from 1 798, together with its 1 795 (?), 1 797 and 1 803 versions, is undoubtedly one of the cartographic monuments developed by Portuguese cartography from the late eighteenth century. Its organizer was the geographer, astronomer, and frigate captain Antonio Pires da Silva Pontes Leme, who relied on the work of 34 people, including astronomers, geographers, and engineers, who, although only mentioned in the 1 798 version, contributed to the creation of all versions. All of them are similar in appearance, but differ in size, content, details, amount, and distribution of toponyms, which will be the subject of another paper. The greatest similarity, however, concerns the defined map projection. The objective of this paper is to analyse and present the possible hypotheses and conclusions about which map projection was adopted for all versions of Nova Lusitania, through the identification of characteristics that allowed to infer and prove the adopted projection. The applied methodology verified that in the bibliographic search, the information about the map structure is insufficient. An article presented by General Djalma Polli Coelho in October 1 950 states that the projection suggested by its title, as orthogonal spherical, appeared to be the Sanson-Flamsteed equal-area projection. However, the expression Carta Geographica de Projecçaõ Espherica Orthogonal allows us to infer also the transverse orthographic projection. Through parameters defined for the two projections, it was possible to establish the comparative elements for a cartographic analysis, which would allow us to conclude and prove the structure adopted for the map, allowing to conclude if the adopted projection for the Nova Lusitania was an azimuthal orthographic equatorial projection, or a Sanson-Flamsteed, sinusoidal projection on the meridian 31 5°, defined west-east, (counterclockwise), from the El Hierro (Ferro) Island. This meridian is referenced approx. -62°39'46" off the Greenwich meridian. [ABSTRACT FROM AUTHOR]

This paper analyses the structural characteristics (shape, position and condition) of landscape patches in Central Lika according to landscape types and for the landscape of Central Lika as a whole. A set of indicators for the landscape structure was used along with GIS technology. Interrelation of the structural characteristics of landscape patches were determined using regression analysis. When determining the landscape types of Central Lika, a method based on land cover/land use was applied. For this purpose, data from the CORINE database for the year 2012 were used. At the level of the landscape type in Central Lika and the landscape of Central Lika as a whole, a set of indicators for the landscape structure were used, based on a variety of spatial analysis methods: Mean Shape Index-for the landscape patch shapes; Core Area Index - for the condition of the landscape patches, and Average Nearest Neighbour - for the position of the landscape patches. The most important result of this paper was to confirm the correlation between the shape and condition, and between the shape and position of the landscape patches of Central Lika, while no correlation between the condition and position of the landscape patches of Central Lika was found.

The aim of this paper, based on three maps of the Croatian lands by Stjepan Glavac, Pierre Duval and Johann Christoph Weigl, is to show or rather prove the presence of propaganda messages in cartography as a scientific discipline. The maps were chosen because in research conducted to date, no propaganda elements conveying hidden messages in the area they depict have been identified. The maps reveal elements of propaganda which will be critically interpreted. In the conclusion, a short review of the paper is presented with all the maps and a personal opinion about the maps as propaganda media of that time. [ABSTRACT FROM AUTHOR]

The paper describes the establishment of a webGIS pilot project in the city of Sinj, based on the research of the development of local spatial data infrastructure (LSDI) as described in the doctoral thesis (Marasović 2020). A set of LSDI development indicatorswere tested in the pilot project. The indicators to be tested were discovered in the mentioned doctoral thesis using statistical regression, statistical correlation and focus groups. The following key indicators have been identified: 1) funding from the local level, 2) awareness, 3) support for development from the decision makers, and 4) administration and citizens recognized as the main LSDI user groups. As an example of LSDI, most main stakeholders of the city of Sinj were interviewed and mapped according to their relevant capabilities, working processes and interaction between the main stakeholders. All the identified indicators were confirmed. The pilot project confirmed that the decision on investment in LSDI from the local level decision makers is essential for its implementation. For such a decision, raising the awareness of the decision makers and citizens about the benefits of LSDI is vital. Citizens and city administration were mapped as two stakeholders which interact most among the stakeholders. Delegating an employee responsible for the implementation and support from the decision makers during the implementation process are essential for success. Human Resources and Public Relationships management activities were recognized as very important in the process of raising awareness of LSDI. [ABSTRACT FROM AUTHOR]

Augmented reality (AR) technology allows cartographers to make cartographic products more attractive and more understandable for their users. In our research experiment we applied new AR technology onto a paper version school geography atlas for grade 8 (15-year-olds). The experiment that we did was carried out with grade 3 students (10-year-olds). The challenge we had was to see how small children would understand the complicated geographic information presented by the atlas using AR. The results show that students deal with the information and understand maps correctly with the help of the newly presented information. The children were very interested and asked to continue lessons. They were even interested in how the atlas was created using AR technology. It is evident that the presented new technology provides us with possibilities of explaining difficult geographic topics to students of different ages. [ABSTRACT FROM AUTHOR]

Ivan Klobučarić was one of the most important Croatian cartographers at the turn of the 17th century. In 1579 he produced a panorama of Rijeka which is kept in the War Archives (Kriegsarchitf in Vienna. The Styrian Provincial Archives (Steiermarkische Landesarchiv) in Graz houses a map of the Bay of Rijeka with a panorama of the city dated 1586, attributed to Klobučarić. His cartographic legacy created between 1601 and 1605 can be found in the Clobucciarich - Skizzen collection. It comprises 108 sheets. Most are double-sided. Some pages show two or more items, so that the entire collection includes around 500 cartographic depictions. In terms of western Croatia, there are about twenty. This paper provides a list of the contents of Klobučarić's cartographic depictions relating to the area of Croatia. A sketch of the Kvarner Littoral from Rijeka to Sveti Juraj with the mainland hinterland is described, with a map of parts of Croatia from Rijeka to Omiš with the mainland hinterland. An analysis was conducted of the contents of the parts of the sketch and map showing the Kvarner Littoral, comparing the representation of settlements showed and those omitted, with toponyms on the map and those shown on earlier maps of the Kvarner Littoral. The paper indicates errors in previous works about Klobučarić's life, work and cartographic activities. [ABSTRACT FROM AUTHOR]

The Web Mercator projection is a projection of a relatively recent date. There has been a lot of controversy about its application. Some believe that this projection is not a projection of either the sphere or the surface of the ellipsoid. Therefore, in this paper, several projections of the surface of a rotational ellipsoid into a plane are investigated and it is shown that the Web Mercator projection is one of such projections. Namely, although the equations of this projection are identical to the equations for the projection of the sphere, the basic difference is in the choice of the area of definition, i.e., the domain of the projection. Furthermore, we have shown that the Web Mercator projection can also be interpreted as double mapping: mapping an ellipsoid to a sphere according to the normals and then mapping the sphere to the plane according to the formulas of the Mercator projection for the sphere. The Web Mercator projection is not a conformal projection, but it is close in properties to the Mercator projection. [ABSTRACT FROM AUTHOR]

This paper presents an analysis and definition of development types and subtypes in the landscape of Central Lika, based on processes of change in the period 1 980 201 2 CORINE Land Cover database data for 1 980 and 201 2 were used to establish the landscape types in Central Lika in those years. The landscape types in Central Lika were determined according to land cover/land use. Based on the mutual relations between the established landscape types in the two observed years, we established six landscape development types and three subtypes in Central Lika. The spatial distribution of landscape development types and subtypes in Central Lika was determined using the Standard Deviational Ellipse (Directional Distribution) spatial analysis method. The results obtained showed that in the observation period (1 980 201 2), most of the area of Central Lika (89.46%) belonged to the Stagnation landscape type. Other development types were present to a much lesser extent (about 5.5%) and were found to be Vegetation succession, Agrarisation, Vegetation degradation and Built-up land. We established a spatial gradation of three phases in the process of vegetation succession, that is, development subtypes from the centre to the margins of the research area. At the same time, in the observation period, the process and trend of extensification of land use in Central Lika was twice as present as intensification. [ABSTRACT FROM AUTHOR]

The paper discusses the possibilities of depicting movement on static thematic maps, using migration as an example - a process which is a part of everyday life, but which may be spatially and temporarily extremely variable. Migrations are mostly depicted using flow maps in demographic literature and elsewhere, for example in daily newspapers. Flow maps are very useful for depicting the movement theme, but migrations, or rather selected components of migration, can also be depicted using other types of thematic maps. The greatest obstacle is the depiction of time, or rather the simultaneous depiction of several years or time periods on a single static thematic map. The paper discusses some possibilities for representing components of migration by using several different types of static thematic maps, their advantages and disadvantages, with the focus on the possibilities and difficulties of mapping spatial and temporal variables on the same map.

The problem of the high mortality rate, in comparison with countries with similar living standards, is extremely urgent in Russia. It is especially noticeable at the regional level, where differences in mortality and its structure are enormous. The regions of Russia are at different stages of epidemiological transition. This is expressed in differences in their mortality rates and differences in the structure of causes of death. The regions and largest cities of the country are sometimes diverge radically, which greatly complicates research. This paper presents a typology of regions and large cities of the Russian Federation according to the main classes of causes of death in 2015 and its cartography. The spatial features of mortality according to the main causes of death are determined separately for men and women. The assessment was carried out using classification by demographic indicators (causes of mortality: some infectious and parasitic diseases; tumours; diseases of the circulatory system; respiratory diseases; diseases of the digestive system; external causes of death). The dataset included 250 territorial units: 85 regions (including cities of federal significance) and 165 large cities with populations of over 100,000. Based on the primary statistics, standardised mortality rates were calculated. The classification was carried out according to an algorithm developed by one of the authors. The classification presented allows us to highlight the specific characteristics of individual groups of regions and analyse them with a greater degree of accuracy. [ABSTRACT FROM AUTHOR]

The paper describes a study of equidistant, standard and secant parallels in normal aspect cylindrical and conical projections. First, the explanation of cylindrical and conical projections as projections on cylindrical or conical surfaces is not recommended because it leads to misunderstanding projection properties. Furthermore, equidistant, standard and secant parallels are often assumed to be identical in references. After defining these three types of parallels, it is proved that it is necessary to differentiate them in the theory of map projections and teaching it. [ABSTRACT FROM AUTHOR]

The features, advantages and disadvantages of using QGIS, ArcGIS and Maplnfo Pro when creating atlases of various types (geographic, complex and thematic) are considered in this paper. Schemes for their potential organization are presented and technological schemes for their automated creation in these geographic information systems are proposed. As a result, approaches and solutions for improving geographic information software can be formulated. Algorithms and modules were developed, primarily aimed at formalizing the structure of atlases and automating the design process of their mathematical basis. The development of functionality was implemented using built-in developer tools implemented in Maplnfo as the MapBasic language, and in ArcGIS and QGIS in the Python programming language. A summary table was compiled, which presents the basic functionalities required to create atlases in GIS and their implementation in the appropriate software. These proposals will ensure the fulfillment of all requirements necessary for atlas design, primarily at the regional mapping level. [ABSTRACT FROM AUTHOR]

The 2nd Geomagnetic Information Renewal Cycle started in 2017, pursuant to a request from the State Geodetic Administration and Ministry of Defence to ensure actual declination and its annual variation across the territory of Republic of Croatia. A test survey was performed at POKUpsko as part of the project in 2017. The PRM1 Primary Repeat Station had been destroyed, and the survey performed at a secondary location established in 2011, which subsequently became the primary location, known as PRM2. In this paper, the results of 2017 measurements reductions are presented, along with reductions in PRM1 and PRM2 measurements in 2011, and differences between the PRM1 and PRM2 locations, which are necessary to maintain the continuity of measurements at Pokupsko.

The identification and analysis of regional disparities are increasingly important issues for a better understanding of regions and their socioeconomic development, and the subsequent application of regional policies. The objective assessment of regional disparities is an important step in directing regional policies by individual countries and supranational institutions such as the European Union. The paper deals with selected indicators of regional socio-economic disparities in the territory of the Czech Republic that were observed, visualized and evaluated to contribute to measuring regional disparities. The indicators were divided into three categories - demographic, economic and infrastructural - and defined and analyzed at the level of the Czech NUTS3 regions (counties), with the data organized as a geodatabase within ArcGIS software. A synthetic index was used to define and analyze the disparities within the three categories. The values for the indicators, along with the results of the regional evaluation, were presented cartographically as a series of cartograms, and the analysis and cartographic visualizations were used to reach conclusions about existing disparities.

It is commonly assumed that standard parallels and parallels that appear as the intersections of a developable surface and a sphere or ellipsoid coincide. This paper shows that this is not true of azimuthal projections which are equidistant along meridians, equidistant along parallels (orthographic), and equal-area, because there is no standard parallel at all in such projections. Only some azimuthal conformal (stereographic) projections have standard parallel, in which case it coincides with secant parallel. [ABSTRACT FROM AUTHOR]

The paper gives a historical account of how the Novi Vinodol astronomic point was created - a point which has been maintained until the present day as a second class trigonometric point. It is the end point of a chain of triangles set up in the early 20th century to establish the halfway parallel, i.e. the parallel corresponding to 45° latitude. The geometric and astronomic works were conceived and led by General Stevan P. Bošković, Director of the Military-Geographic Institute in Belgrade. [ABSTRACT FROM AUTHOR]
