The model is an extension of the IndoorGML standard navigation module with a twofold benefit: the extension facilitated the data import from the international standard CityGML and introduced the semantics of various fixtures in indoor space of buildings making the navigation model more suitable for human needs. Several experiments have been conducted by extracting networks from CityGML data and performing a comparison with other network construction techniques. The second contribution of the paper is an algorithm for the automatic extraction of the navigation network. Such an algorithm is a hybrid solution between medial axis approaches and visibility graph approaches. Normally, medial axes approaches are a good representation of human navigation in narrow corridors, especially to avoid obstacles, but introduce distortions in open space. On the other hand, visibility approaches work better in open spaces. In our extraction technique, the resulting network takes advantages of both approaches and better mimics human beings’ navigation in indoor environments.

Crowdsourcing geographic information with a gamification approach / Roberta Martella in Geodetski vestnik, vol 63 n° 2 (June - August 2019)  

Public [article]  inGeodetski vestnik > vol 63 n° 2 (June - August 2019) . - pp 213 - 233 Titre : Crowdsourcing geographic information with a gamification approach Type de document : Article/Communication Auteurs : Roberta Martella, Auteur ; Eliseo Clementini, Auteur ; Christian Kray, Auteur Année de publication : 2019 Article en page(s) : pp 213 - 233 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] application web [Termes IGN] contenu généré par les utilisateurs [Termes IGN] données localisées des bénévoles [Termes IGN] production participative [Termes IGN] téléphone intelligent Résumé : (auteur) Crowdsourcing geographic information has been a massive phenomenon that took place over the last two decades and that changed dramatically the diffusion of geographic data in society. The availability and readiness of geographic information is paramount in practically all software systems and services and this is strongly determined by the drive of people putting energy in data collection and improvement. Understanding the motivations of people to participate in this process is fundamental to leverage the design of new systems able to increase satisfaction and productivity. The introduction of game mechanisms in geographic crowdsourcing is the theme that we face in this research. The so-called gamification of applications has been widely used as a stimulant for involving people in serious activities that are hidden behind the gaming façade. Cooperation and competition are key factors that are promoted through the game. We synthesize a conceptual model that collects the main gaming techniques tailored for geographic data and that is the basis for the development of a gamification library. As a proof of concept, we deploy an Android app for geometric data collection inside buildings and test it in a university setting.

Data trustworthiness and user reputation as indicators of VGI quality / Paolo Fogliaroni in Geo-spatial Information Science, vol 21 n° 3 (October 2018)  

Public [article]  inGeo-spatial Information Science > vol 21 n° 3 (October 2018) . - pp 213 - 233 Titre : Data trustworthiness and user reputation as indicators of VGI quality Type de document : Article/Communication Auteurs : Paolo Fogliaroni, Auteur ; Faust d' Antonio, Auteur ; Eliseo Clementini, Auteur Année de publication : 2018 Article en page(s) : pp 213 - 233 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Bases de données localisées [Termes IGN] contributeur [Termes IGN] données localisées des bénévoles [Termes IGN] fiabilité des données [Termes IGN] indicateur de qualité [Termes IGN] utilisateur Résumé : (Auteur) Volunteered geographic information (VGI) has entered a phase where there are both a substantial amount of crowdsourced information available and a big interest in using it by organizations. But the issue of deciding the quality of VGI without resorting to a comparison with authoritative data remains an open challenge. This article first formulates the problem of quality assessment of VGI data. Then presents a model to measure trustworthiness of information and reputation of contributors by analyzing geometric, qualitative, and semantic aspects of edits over time. An implementation of the model is running on a small data-set for a preliminary empirical validation. The results indicate that the computed trustworthiness provides a valid approximation of VGI quality.

Directional relations and frames of reference / Eliseo Clementini in Geoinformatica, vol 17 n° 2 (April 2013)  

Public [article]  inGeoinformatica > vol 17 n° 2 (April 2013) . - pp 235 - 255 Titre : Directional relations and frames of reference Type de document : Article/Communication Auteurs : Eliseo Clementini, Auteur Année de publication : 2013 Article en page(s) : pp 235 - 255 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] langage de requête [Termes IGN] navigation terrestre [Termes IGN] prise en compte du contexte [Termes IGN] réflectance de surface [Termes IGN] relation spatiale [Termes IGN] repère de référence [Termes IGN] taxinomie Résumé : (Auteur) As an intermediate category between metric and topology, directional relations are as much varied as “right of”, “before”, “between”, “in front of”, “back”, “north of”, “east of”, and so on. Directional relations are ambiguous if taken alone without the contextual information described by frames of reference. In this paper, we identify a unifying framework for directional relations and frames of reference, which shows how a directional relation with its associated frame of reference can be mapped to a projective relation of the 5-intersection model. We discuss how this knowledge can be integrated in spatial query languages.
