The limits of GIS: Towards a GIS of place / Alberto Giordano in Transactions in GIS, vol 22 n° 3 (June 2018)  

Public [article]  inTransactions in GIS > vol 22 n° 3 (June 2018) . - pp 664 - 676 Titre : The limits of GIS: Towards a GIS of place Type de document : Article/Communication Auteurs : Alberto Giordano, Auteur ; Tim Cole, Auteur Année de publication : 2018 Article en page(s) : pp 664 - 676 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes d'information géographique [Termes IGN] Budapest [Termes IGN] corpus [Termes IGN] réseau social [Termes IGN] système d'information géographique Résumé : (Auteur) In this article, we reflect back on our decade‐long collaboration on the geographies of the Holocaust to argue for a GIS of place. Our previous work on ghettoization in Budapest and on the spatio‐temporal patterns of Jewish persecution in Italy had a marked spatial dimension, both in the research questions we set out to answer and the methods we used, which were largely quantitative. During the course of our research, we progressively came to realize that a spatial perspective favors the voice of the perpetrator and that to fully comprehend and understand the geography of the Holocaust, we needed to engage with the voice of the victim, extend the set of methods and tools used, and broaden our epistemology. While proposing a fully‐fledged model of a qualitative GIS of the places and spaces of the Holocaust is beyond the scope of this article, we: (a) argue for the integration of social network analysis, corpus linguistics, and spatio‐temporal methods and for a mixed‐methods analytical approach and (b) note how the topological and relational foundations we identify as fundamental to a GIS of place parallel the long‐standing call for an “integrated history” of the Holocaust.

Extraction of spatio‐temporal data about historical events from text documents / Susanna Abraham in Transactions in GIS, vol 22 n° 3 (June 2018)  

Public [article]  inTransactions in GIS > vol 22 n° 3 (June 2018) . - pp 677 - 696 Titre : Extraction of spatio‐temporal data about historical events from text documents Type de document : Article/Communication Auteurs : Susanna Abraham, Auteur ; Stephan Mäs, Auteur ; Lars Bernard, Auteur Année de publication : 2018 Article en page(s) : pp 677 - 696 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications SIG [Termes IGN] base de données historiques [Termes IGN] histoire [Termes IGN] recherche d'information géographique [Termes IGN] Time-geography [Termes IGN] traitement du langage naturel Résumé : (Auteur) Often, we are faced with questions regarding past events and the answers are hidden in the historical text archives. The growing developments in geographic information retrieval and temporal information retrieval techniques have given new ways to explore digital text archives for spatio‐temporal data. The question is how to retrieve the answers from the text documents. This work contributes to a better understanding of spatio‐temporal information extraction from text documents. Natural language processing techniques were used to develop an information extraction approach using the GATE language processing software. The developed framework uses gazetteer matching, spatio‐temporal relationship extraction and pattern‐based rules to recognize and annotate elements in historical text documents. The extracted spatio‐temporal data is used as input for GIS studies on the time–geography context of the German–Herero resistance war of 1904 in Namibia. Related issues when analyzing the historical data in current GIS are discussed. Particularly problematic are movement data in small scale with poor temporal density and trajectories that are short or connect very distant locations.

Acts 2, verse 9 to 11 is the text of study. Case study 1 applies network analysis to data representing the Roman road network constrained by parameters valid for ancient times. This analysis provided new information on the background of people attending a festival in Jerusalem. Case study 2 located geographical entities from the text in a cartographic visualization and provided supportive information to compare contemporary textual resources. For the disciplines of textual and conjectural criticism (case study 3), spatio‐temporal analysis opens a new window to study what would be the most probable variant of the original text. The case study puts emendations that have been proposed over centuries in a 3D spatial context and provides in this way a sophisticated tool to relate different alternative variants of a specific text. From the case studies, it can be concluded that spatializing, visualizing, and spatially analyzing geographical concepts from the texts in Acts 2 contributes to the field of New Testament interpretation. Further work will elaborate on the findings.

Creating a conceptual framework to improve the re‐usability of open geographic data in cities / Fernando Benitez‐Paez in Transactions in GIS, vol 22 n° 3 (June 2018)  

Public [article]  inTransactions in GIS > vol 22 n° 3 (June 2018) . - pp 806 - 822 Titre : Creating a conceptual framework to improve the re‐usability of open geographic data in cities Type de document : Article/Communication Auteurs : Fernando Benitez‐Paez, Auteur ; Alexis Comber, Auteur ; Sergio Trilles, Auteur ; Joaquin Huerta, Auteur Année de publication : 2018 Article en page(s) : pp 806 - 822 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Infrastructure de données [Termes IGN] cadre conceptuel [Termes IGN] collectivité territoriale [Termes IGN] Colombie [Termes IGN] données localisées numériques [Termes IGN] données ouvertes [Termes IGN] Espagne [Termes IGN] indicateur [Termes IGN] réutilisation des données [Termes IGN] Valence (Espagne) Résumé : (Auteur) Open data has a profound effect on the working environment within which information is created and shared at all levels. At the local government level, open data initiatives have resulted in higher transparency in policy, a greater engagement between decision‐makers and citizens, and have changed the culture about how data analysis and evidence are used to support local governance. This article, based on data collected through an on‐line survey, participatory workshops with data user communities in four cities (in Colombia and Spain), and interviews with Valencia good‐government office, identifies four elements for a conceptual framework to improve the re‐usability of open geographic data in cities. The essential elements defined in this research are the definition of data user communities and their needs, the creation of the community of reuse, user‐focused metadata, and reuse‐focused legal terms. The definition of these indicators provides a framework for authorities to re‐shape their current open data strategy to include data user requirements. At the end of this article, a roadmap for future research and implementation is presented, considering some reflections on the conceptual framework.

Modeling aggregated expertise of user contributions to assess the credibility of OpenStreetMap features / Bani Idham Muttaqien in Transactions in GIS, vol 22 n° 3 (June 2018)  

Public [article]  inTransactions in GIS > vol 22 n° 3 (June 2018) . - pp 823 - 841 Titre : Modeling aggregated expertise of user contributions to assess the credibility of OpenStreetMap features Type de document : Article/Communication Auteurs : Bani Idham Muttaqien, Auteur ; Franck O. Ostermann, Auteur ; Robert Lemmens, Auteur Année de publication : 2018 Article en page(s) : pp 823 - 841 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Bases de données localisées [Termes IGN] contenu généré par les utilisateurs [Termes IGN] données localisées des bénévoles [Termes IGN] expertise [Termes IGN] fiabilité des données [Termes IGN] OpenStreetMap [Termes IGN] qualité des données [Termes IGN] utilisateur civil Résumé : (Auteur) The emergence of volunteered geographic information (VGI) during the past decade has fueled a wide range of research and applications. The assessment of VGI quality and fitness‐of‐use is still a challenge because of the non‐standardized and crowdsourced data collection process, as well as the unknown skill and motivation of the contributors. However, the frequent approach of assessing VGI quality against external data sources using ISO quality standard measures is problematic because of a frequent lack of available external (reference) data, and because for certain types of features, VGI might be more up‐to‐date than the reference data. Therefore, a VGI‐intrinsic measure of quality is highly desirable. This study proposes such an intrinsic measure of quality by developing the concept of aggregated expertise based on the characteristics of a feature's contributors. The article further operationalizes this concept and examines its feasibility through a case study using OpenStreetMap (OSM). The comparison of model OSM feature quality with information from a field survey demonstrates the successful implementation of this novel approach.

Quality assessment in point feature generalization with pattern preserved / Wenhao Yu in Transactions in GIS, vol 22 n° 3 (June 2018)  

Public [article]  inTransactions in GIS > vol 22 n° 3 (June 2018) . - pp 872 - 888 Titre : Quality assessment in point feature generalization with pattern preserved Type de document : Article/Communication Auteurs : Wenhao Yu, Auteur Année de publication : 2018 Article en page(s) : pp 872 - 888 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] analyse texturale [Termes IGN] objet géographique ponctuel [Termes IGN] qualité du processus [Vedettes matières IGN] Généralisation Résumé : (Auteur) Geographical features often show certain spatial patterns on a map in terms of the arrangement of point symbols. These patterns are essentially related to the underlying geographical processes and landscapes. Thus, when deriving small‐scale maps from a large‐scale map, one of the most important constraints that cartographers or systems should follow is to retain the basic patterns of point objects on the target map. However, no research in the literature currently evaluates the quality of point feature generalization in terms of spatial pattern. This study proposes an approach to quantitatively measure the pattern change after generalization. The basic idea of the approach is to extend advanced image analysis techniques (e.g., texture recognition) to measure the patterns of point objects in a map space. Specifically, there are two main steps: firstly, the original space is converted into the raster space by utilizing a regularly spaced grid (i.e., a grayscale image) with cell attributes representing the local intensity level of point features; secondly, the texture analysis operation is performed on the grid to obtain the feature descriptors of the point pattern. The experimental results demonstrate that the proposed approach is effective in comparing the point patterns before and after generalization.
