The description of the nature and shape of the cartographic line has been a challenging research area in contemporary cartography. The digital character of the line, while representing a tempting research element, reveals the extent of the problems related to line character assessment because of the practically unlimited number of forms the cartogr...

Navigation at sea is based on Electronic Chart Display and Information Systems (ECDIS) that allow for the use of a limited number of projections. As navigation in the Arctic region becomes a reality due to the progressive melting of the polar ice cap, a re-examination of the most suitable projections for navigation in the Arctic becomes timely. Sev...

OpenStreetMap (OSM) is the most successful example of Volunteered Geographic Information (VGI). It is also the most frequently used case study in research that focuses on VGI quality, as it is usually considered a proxy for other VGI projects. The research in this area usually focuses on comparisons with authoritative data, measurements and quality...

Land-use maps are necessary for planning at the neighbourhood and municipal level as well as at the regional and country level. However, each scale requires different level of detail. Generalisation is a fundamental cartographic procedure used in map production, which allows the transition from a larger scale to a smaller one. In this research, Hel...

The flourishing of VGI projects has transformed the average web user into an eager geographic data user and contributor. As it is difficult for the crowd to perceive VGI quality, visualisation can play a critical role in communicating data quality. At the same time, although VGI quality has been a prominent research topic for scientists, quality vi...

Despite the considerable growth in Volunteered Geographic Information (VGI) activities in citizen sensing and the evident opportunities for VGI use in map revision and updating, few European National Mapping Agencies (NMAs) or other types of government bodies have engaged significantly with VGI. Moreover , the level of engagement of NMAs with the V...

The most common way to use geographic information is to make maps. With the ever growing amount of Volunteered Geographic Information (VGI), we have the opportunity to make many maps, but only automatic cartography (generalisation, stylisation, text placement) can handle such an amount of data with very frequent updates. This chapter reviews the re...

With the opening up of the Landsat archive, global high resolution land cover maps have begun to appear. However, they often have only a small number of high level land cover classes and they are static products, corresponding to a particular period of time, e.g., the GlobeLand30 (GL30) map for 2010. The OpenStreetMap (OSM), in contrast, consists o...

A protocol for the collection of vector data in Volunteered Geographic Information (VGI) projects is proposed. VGI is a source of crowdsourced geographic data and information which is comparable, and in some cases better, than equivalent data from National Mapping Agencies (NMAs) and Commercial Surveying Companies (CSC). However, there are many dif...

Η εντυπωσιακή ανάπτυξη των Εθελοντικών Γεωγραφικών Δεδομένων (ΕΓΔ) μετέτρεψε το μέσο χρήστη του διαδικτύου σε ένα δυναμικό δημιουργό και χρήστη γεωγραφικών δεδομένων. Καθώς ο απλός χρήστης δύσκολα κατανοεί το θέμα της ποιότητας των ΕΓΔ, η χαρτογραφική απόδοση της ποιότητας μπορεί να παίξει ένα σημαντικό ρόλο. Παράλληλα, ενώ η ποιότητα των ΕΓΔ αποτε...

Τα μεταδεδομένα είναι ιδιαίτερα χρήσιμα καθώς διευκολύνουν την αναζήτηση και τον εντοπισμό των γεωγραφικών δεδομένων, επιτυγχάνουν τη διαλειτουργικότητα και μπορούν να οδηγήσουν σε συμπεράσματα για την καταλληλότητα χρήσης. Όμως, παρόλο που έχουν διατυπωθεί πρότυπα για την καταγραφή μεταδεδομένων για τα γεωγραφικά δεδομένα, αυτά δεν συλλέγονται πάν...

Ένα μεγάλο μέρος των χαρτών που συντάσσονται σήμερα προορίζονται για δημοσιοποίηση στο διαδίκτυο. Η αλλαγή αυτή, σε σχέση με τον παραδοσιακό στόχο που ήταν ο έντυπος χάρτης, επηρεάζει τη διαδικασία σχεδιασμού σε πρακτικό επίπεδο π.χ. νέες τεχνολογίες, λογισμικό και προγραμματιστικές τεχνικές. Η ανάγκη της χαρτογραφικής σύνθεσης να προσαρμοστεί στις...

The appearance of OpenStreetMap (OSM) in 2004 sparked a phenomenon known as Volunteered Geographic Information (VGI). Today, VGI comes in many flavours (e.g. toponyms, GPS tracks, geo-tagged photos, micro-blogging or complete topographic maps) and from various sources. One subject that has attracted research interest from the early days of VGI is h...

This paper presents a comparative study of several simplification algorithms and their influence on two elements inherent to linear features: shape and horizontal position. Algorithms, which use different criteria for vertex elimination, are applied to lines with different shape complexity, using a range of tolerance values to produce generalizatio...

Generalization of linear features is considered to be among the most important generalization operations. This is due to the fact, that the majority of map features are represented as lines or polygons, which are bounded by lines. Usually the results of a generalization transformation are evaluated visually, mostly based on aesthetic criteria and l...

The process of geovisualization involves scientific techniques which are implemented in order to represent spatiotemporal information that describes geographic entities and phenomena. The application of geovisualization methods allows the visual exploration of geospatial data using static, animated, and interactive cartographic products. The majority of spatial analysis and geographic information system applications resulted in specific representations which could substantially support the identification of potential relationships, patterns and trends related to the spatial and temporal distribution of geographic data. Hence, the geovisualization process has become an essential part of different crucial research/scientific and professional domains. Undoubtedly, the immense availability of both open source and proprietary software tools, the considerable number of available sensors and devices, as well as the freely distributed geospatial data have contributed toward this direction. However, the popularity that geovisualization methods have gained implies several challenges and new solutions, especially considering the advent of the Big Data era. This Special Issue aims to collect innovative and high-quality research articles related to current trends and challenges in the field of geovisualization in 2D and 3D. Additionally, possible contributions could describe specific applications in several related domains. Comprehensive and systematic literature review articles in the field are also welcome. More specifically, potential topics include (but are not limited to) the followings: - New geovisualization design methods; - Geovisualization variables and principles; - Evaluation and/or comparison of different geovisualization methods; - New geovisualization software tools; - Theoretical and experimental studies in geovisualization; - Geovisualization and Big Data; - Geovisualization and VR/AR applications; - Geovisualization in local, mobile, and web environments; - Printed and digital map collections; - Geovisualization applications in different fields (e.g., spatial analysis and planning, environment, climate change, hydrology, geology, history, education, archaeology, epidemiology, biology); Comprehensive and systematic literature reviews on any of the aforementioned topics. Special Issue Guest Editors: - Dr. Vassilios Krassanakis (Department of Surveying and Geoinformatics Engineering, School of Engineering, University of West Attica). - Dr. Andriani Skopeliti (Cartography Laboratory, School of Rural, Surveying and Geoinformatics Engineering (SRSE), National Technical University of Athens). - Dr. Merve Keskin (Department of Geoinformatics and Cartography, Finnish Geospatial Research Institute (FGI), National Land Survey of Finland). - Dr. Paweł Cybulski (Department of Cartography and Geomatics, Faculty of Geographical and Geological Sciences, Adam Mickiewicz University).
