Cilj je rada demonstrirati metodologiju korištenja digitalnog modela cesta, definiranje optimalnih parametara za izradu cestovnog grafa i georeferenciranje nastalih događaja radi određivanja indeksa prostorne autokorelacije prometnih nesreća, u potpunosti koristeći otvorene podatke. Da bi se postigao taj cilj, upotrebljava se temelj međunarodne normizacije postavljen u ISO 19 100 – Geografske informacije u kombinaciji s metodom prostorne autokorelacije, proširenom za mrežu, praktično primijenjenom kroz mogućnosti programskog jezika Python kao elementa Geoinformacijskog sustava prometnih nesreća. Obrađeni su podatci otvorenog koda s geoportala OpenStreetMap, kao i stvarni arhivski podatci za 1288 teških nesreća na području grada Sofije u Bugarskoj, te je izračunat koeficijent prostorne autokorelacije kako bi se utvrdila ovisnost ili neovisnost broja prometnica nesreća između pojedinih područja svojom točnošću i pouzdanošću. Rezultat je definiranje ispravne osnove za provedbu prostorne analize s postavljanjem temelja za naknadno proučavanje različitih čimbenika i definiranje niza razloga čije će utvrđivanje dovesti do smanjenja ozljeda u prometu.","PeriodicalId":35029,"journal":{"name":"Kartografija i Geoinformacije","volume":"32 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140511368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":35029,"journal":{"name":"Kartografija i Geoinformacije","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45233132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach for international standardization and conceptual modeling of geoinformation, as well as the principles of object-oriented modeling, methods of abstraction and classification were used. As a result, a Use Case and a Class diagram, presented in the Unified Modeling Language, were developed. In conclusion, the standardized conceptual model is defined as an important initial stage in the creation of a geoinformation system of road accidents, which is related to the correct formalized description of the domain and the presentation of structural types of geoinformation processes, and subsequently can be automatically and in the unified manner transposed into a functional physical model for the analysis of road accidents.","PeriodicalId":35029,"journal":{"name":"Kartografija i Geoinformacije","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44489623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because data are often communicated graphically, many colleges and universities are offering courses that teach the principles of data visualisation. In this article, the author reflects on his experience of teaching such a course at a liberal arts college. The course introduced students to the tidyverse suite of packages for the programming language R, including the data visualisation package ggplot2, which implements Wilkinson’s (2005) ‘grammar of graphics’. The packages sf and tmap were used to extend the capabilities of the tidyverse packages for analysing geospatial data and producing thematic maps. This article provides insights into effective teaching strategies, including intended learning outcomes, the core syllabus, pedagogy and assessment. Sample tasks and visualisations are also presented to demonstrate how essential cartographic skills were imparted to students.","PeriodicalId":35029,"journal":{"name":"Kartografija i Geoinformacije","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47375142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research results suggest that the cartographers who made geographic maps relied significantly on Claudius Ptolemy’s data on locations but managed to make certain accuracy improvements. The nautical charts with graticules showed significantly greater longitudinal accuracy, which suggests that they were created by using other data sources as their graphical templates; most likely the portolan charts that were already in existence at the time.","PeriodicalId":35029,"journal":{"name":"Kartografija i Geoinformacije","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49049370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":35029,"journal":{"name":"Kartografija i Geoinformacije","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46469241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regardless of their purpose, which could range from ideological representations of the medieval world, as were O or T maps, to practical sailing maps like portolan charts and other early modern nautical charts of the (already known) world in a smaller scale, they carried the standard scope of geo-cartographic data and content. Besides, they offered a rich illustrative component of respectable graphic quality. This depended on the purpose of the map, as well as the geographical knowledge of its author on one hand and on the skill and expertise of its creator on the other. Through this short synchronic and diachronic overview of the iconographic elements of Old World maps, especially in respect to Croatian lands, some chronological continuities of cartographic presentation were revealed.

{"title":"Spatial Analysis of Changes in the Demographic Characteristics of the Cres-Lošinj Area Using the GIS Model","authors":"Marta Hamzić","doi":"10.32909/kg.21.38.1","DOIUrl":"https://doi.org/10.32909/kg.21.38.1","url":null,"abstract":"The paper aims to carry out a spatial analysis of the changes in selected demographic characteristics of the Cres-Lošinj area using the GIS model. For this purpose, data from all censuses carried out so far (1857−2021) were used, which were primarily analyzed cartographically by using Mean Center and the Standard Deviational Ellipse (Directional Distribution) spatial analysis methods, which are an integral part of the basic software package ArcGIS Desktop version 10.0 produced by ESRI. Tabular and graphical appendices were used to additionally complement the analyses. The analyses were carried out on three levels: the level of the Cres-Lošinj area as a whole, the individual level of the Town of Cres and the Town of Mali Lošinj, and the level of settlements. For the area of Cres-Lošinj as a whole, the results showed a tendency of the mean center of the population moving towards the north in the 1857−1948 period, then towards the southwest in the 1948−1991 period, while in subsequent censuses the tendency was again towards the north. Among the local self-government units, a common feature of the movement of the mean center of the population is that in the observed period (1857−2021), and particularly the last observed year (2021), the mean centers of the population are very close to the center of the town/municipality. Using the standard deviational ellipse (directional distribution) method, it was determined that larger settlements (Mali Lošinj, Cres and Veli Lošinj) have an increasing influence on the population direction, and it was determined that the population is concentrated closer to the larger settlements, i.e. to the centers of local self-government, while at the same time the influence on the directional distribution of the population of a large number of small settlements in the northern part of the research area decreased due to an increasing reduction in the number of inhabitants. The GIS model used in this study is suitable for researching the complexity of the demographic dynamics of the so-called of small populations because it enables an analysis at multiple spatial levels and contains methods of spatial analysis that use absolute numbers.","PeriodicalId":35029,"journal":{"name":"Kartografija i Geoinformacije","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48561305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
