Visualization of the Invisible (Editorial) / Terje Midtbo in Journal of Geovisualization and Spatial Analysis, vol 5 n° 1 (June 2021)  

Public [article]  inJournal of Geovisualization and Spatial Analysis > vol 5 n° 1 (June 2021) . - n° 13 Titre : Visualization of the Invisible (Editorial) Type de document : Article/Communication Auteurs : Terje Midtbo, Auteur ; Lars Harrie, Auteur Année de publication : 2021 Article en page(s) : n° 13 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] phénomène géographique [Termes IGN] visibilité [Vedettes matières IGN] Géovisualisation Résumé : (auteur) Visualizing geographical phenomena often involve communication of information and relationships through a map in either 2D or 3D. In many cases, the information conveyed through the map is a simplified and symbolic depiction of phenomena that is visible in our physical environment. However, maps are also effective for the communication of geographical phenomena that are hidden or are by nature “invisible” for the human eye. As well as invisible factors in our present environment, tracks of occurrences and events from the past have often been lost for many years. In the same way, future situations have still not materialized. This issue covers all these situations. From historical landscapes and events in the past, cadastre and underground geology today and urban planning for the future. The use of traditional cartographic techniques as well as virtual reality are discussed. Several of the research projects involve user studies. The main objectives contributing papers are to make the “invisible” information accessible and more understandable for humans.

The result of this integration – broadly termed as GeoBIM – has a range of potential uses from district study to road safety. However, from the data perspective, this integration raises the question of how to integrate very detailed design and construction data from the BIM domain with contextual geospatial data (both 2D and 3D) that model a very diverse range of aspects of the wider built and natural environment. This paper reports work carried out during the second phase of the EuroSDR GeoBIM project, which sets out to understand the general status of GeoBIM across Europe with particular focus from a National Mapping and Cadastral Agency perspective. The first phase of the project reviewed the current status of GeoBIM in participating countries and identified the need for specific detailed use cases to overcome both the lack of awareness and the lack of understanding of the potential of GeoBIM. We present both an update on the current status of GeoBIM, and additional details of one of the selected use cases relating to planning/development permits. For the latter, we have been able to develop a detailed workflow highlighting specific data exchange points within the process to issue a development permit, allowing a more in-depth identification of both the roles and data needs at each stage.

Synchronising geometric representations for map mashups using relative positioning and Linked Data / Weiming Huang in International journal of geographical information science IJGIS, vol 32 n° 5-6 (May - June 2018)

This simple overlay approach often raises geometric deficiencies due to geometric uncertainties in the data. This issue is particularly apparent in a multi-scale context because the thematic data seldom have synchronised level of detail with the base map. In this study, we propose, develop, implement and evaluate a relative positioning approach based on shared geometries and relative coordinates to synchronise geometric representations for map mashups through several scales. To realise the relative positioning between datasets, we adopt a Linked Data–based technical framework in which the data are organised according to ontologies that are designed based on the GeoSPARQL vocabulary. A prototype system is developed to demonstrate the feasibility and usability of the relative positioning approach. The results show that the approach synchronises and integrates the geometries of thematic data and the base map effectively, and the thematic data are automatically tailored for multi-scale visualisation. The proposed framework can be used as a new way of modelling geospatial data on the Web, with merits in terms of both data visualisation and querying.

Matching authority and VGI road networks using an extended node-based matching algorithm / Ehsan Abdolmajidi in Geo-spatial Information Science, vol 18 n° 2 (August 2015)  

Public [article]  inGeo-spatial Information Science > vol 18 n° 2 (August 2015) . - pp 65 - 80 Titre : Matching authority and VGI road networks using an extended node-based matching algorithm Type de document : Article/Communication Auteurs : Ehsan Abdolmajidi, Auteur ; Ali Mansourian, Auteur ; Julian Will, Auteur ; Lars Harrie, Auteur Année de publication : 2015 Article en page(s) : pp 65 - 80 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Infrastructure de données [Termes IGN] appariement topologique [Termes IGN] base de données routières [Termes IGN] données localisées de référence [Termes IGN] données localisées des bénévoles [Termes IGN] OpenStreetMap [Termes IGN] qualité des données [Termes IGN] relation topologique [Termes IGN] réseau routier [Termes IGN] Suède Résumé : (auteur) The amount of volunteered geographic information (VGI) has increased over the past decade, and several studies have been conducted to evaluate the quality of VGI data. In this study, we evaluate the completeness of the road network in the VGI data set OpenStreetMap (OSM). The evaluation is based on an accurate and efficient network-matching algorithm. The study begins with a comparison of the two main strategies for network matching: segment-based and node-based matching. The comparison shows that the result quality is comparable for the two strategies, but the node-based result is considerably more computationally efficient. Therefore, we improve the accuracy of node-based algorithm by handling topological relationships and detecting patterns of complicated network components. Finally, we conduct a case study on the extended node-based algorithm in which we match OSM to the Swedish National Road Database (NVDB) in Scania, Sweden. The case study reveals that OSM has a completeness of 87% in the urban areas and 69% in the rural areas of Scania. The accuracy of the matching process is approximately 95%. The conclusion is that the extended node-based algorithm is sufficiently accurate and efficient for conducting surveys of the quality of OSM and other VGI road data sets in large geographic regions.

Analytical estimation of map readability / Lars Harrie in ISPRS International journal of geo-information, vol 4 n°2 (June 2015)  

Public [article]  inISPRS International journal of geo-information > vol 4 n°2 (June 2015) . - pp 418 - 446 Titre : Analytical estimation of map readability Type de document : Article/Communication Auteurs : Lars Harrie, Auteur ; Hanna Stigmar, Auteur ; Milan Djordjevic, Auteur Année de publication : 2015 Article en page(s) : pp 418 - 446 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] apprentissage dirigé [Termes IGN] distribution spatiale [Termes IGN] généralisation cartographique automatisée [Termes IGN] lisibilité perceptive [Termes IGN] régression multiple [Termes IGN] séparateur à vaste marge [Termes IGN] seuillage [Termes IGN] test de performance [Termes IGN] utilisateur [Vedettes matières IGN] Cartologie Résumé : (auteur) Readability is a major issue with all maps. In this study, we evaluated whether we can predict map readability using analytical measures, both single measures and composites of measures. A user test was conducted regarding the perceived readability of a number of test map samples. Evaluations were then performed to determine how well single measures and composites of measures could describe the map readability. The evaluation of single measures showed that the amount of information was most important, followed by the spatial distribution of information. The measures of object complexity and graphical resolution were not useful for explaining the map readability of our test data. The evaluations of composites of measures included three methods: threshold evaluation, multiple linear regression and support vector machine. We found that the use of composites of measures was better for describing map readability than single measures, but we could not identify any major differences in the results of the three composite methods. The results of this study can be used to recommend readability measures for triggering and controlling the map generalization process of online maps.
