[Termes IGN] système d'information géographiqueRésumé : (auteur) Dans le cadre du projet de recherche Urbi&Orbi, l’objectif de cet article est de proposer une méthode de construction et d’analyse des réseaux orbitèles numériques afin d’étudier certaines de leurs propriétés théoriques, avant toute application réelle en milieu urbain ou anthropisé. Les outils utilisés sont un Système d’Information Géographique associant QGIS et PostGIS et un simulateur de modèles à base d’agents (NetLogo). Ces types de réseau sont comparés aux réseaux rectilinéaires et en treillis. Une propriété dite de «rectitude» (ou «straightness») et une mesure de «centralité intermédiaire» (ou «charge») du réseau sont étudiées et discutées.

[Termes IGN] service fondé sur la positionRésumé : (auteur) Our lives are affected by myriads of events happening daily all over the world. For efficient planning and management of complex systems composed of various components, understanding relationships between an event and the reactive behaviour of involved components is vital. Analysing these complex relations demands a spatiotemporal event-based model, in which the event plays a central role. In this article we develop a framework which provides the possibility of mapping and storing event-related information on the OpenStreetMap (OSM) platform by volunteers. The study is divided into two different phases: first, mapping the event elements by adding new attributes adequately designed to encode spatiotemporal and semantic event information; and, second, representing the event-related information on a map by developing a Web application, offering a volunteered location-based service. To facilitate the event-mapping procedure, a Java OpenStreetMap (JOSM) plug-in was developed for volunteers. The plug-in was developed based on the notion of an event to adequately store and manipulate the semantic information of events in the OSM structure. The tool was used by more than 100 volunteers in Munich for the years 2012 to 2014. In addition to manual collection of event-related information by volunteers, a crawling framework was also developed to automatically collect freely available event information from various Web pages on the Internet. The framework extracts the same event elements as the plug-in. But the framework crawls each Web page according to some pre-defined rules and follows a post-processing step, if necessary. The manually collected events along with the crawled event information are visualized in a Web application. The study revealed that adding the possibility of event-oriented mapping to OSM empowers volunteers to collect a higher level of information (event information) for city maps. This information can furthermore be used for strategy development and service planning by decision-makers.

[Termes IGN] retard troposphériqueRésumé : (auteur) Observation data sets from three different periods and 23 International GNSS Service (IGS) stations spread over the world were processed in static mode using four online free precise point positioning (PPP) services: Automatic Precise Positioning Service (APPS), GPS Analysis and Positioning Software, Canadian Spatial Reference System precise point positioning service, and Magic-PPP. The estimated positions of the 23 IGS stations were compared with the published values. The estimated zenith tropospheric delays (ZTDs) at these stations were compared with the corresponding IGS troposphere products published on the IGS Web site. Furthermore, in order to analyze PPP precision for short observation periods, GPS observation data sets with a sampling rate of 1 s collected by one CORS station were also processed by the four online PPP services. Calculation shows that the precision of daily solutions for north and east (N/E) components estimated by the four online PPP services can reach millimeter level, the precision of ellipsoid elevation (H) can reach 1–2 cm, and precision of ZTDs estimation results is approximately 1–2 cm. Compared with the corresponding values published on the IGS Web site, the precision of ZTDs estimated by APPS is higher than those estimated by the other three PPP online services; the differences between ZTDs by APPS and IGS values are mostly within ±1 cm. For PPP with short observation periods, the precision of N/E components within 2, 1, and 0.5 h observation periods can reach about 2–3, 2–7, and 3–8 cm, respectively, while the precision of H components is about 3–5, 5–12, and 10–18 cm, respectively.

[Termes IGN] littoral méditerranéenRésumé : (auteur) Desertification is a complex environmental phenomenon that affects many regions worldwide, including the Mediterranean area. Its effects, primarily resulting from climate variations and also influenced by human-induced changes, impact upon potential regional progress due to significant economic losses, social problems and ecological damage. The aim of this study was the identification of sensitive areas to desertification at watershed scale, in the Bradano River basin (Basilicata, southern Italy). The analysis was carried out by means of the model developed within the European project MEDALUS (MEditerranean Desertification And Land USe), which identifies prone areas to desertification through the Environmentally Sensitive Areas (ESAs) index. The model parameters were implemented and processed using a GIS-based approach to evaluate climate, soil, vegetation and management system quality factors, which represent the input for the ESAs assessment. The results indicate that 35% of the study area is highly sensitive to desertification, 49% of the study area has moderate sensitivity to desertification, 12% has low sensitivity and only 4% is non-sensitive to desertification.

[Termes IGN] simple différenceRésumé : (auteur) We develop a new integrated navigation system, which integrates GPS precise point positioning (PPP) with low-cost micro-electro-mechanical sensors (MEMS) inertial system, for precise positioning applications. Currently, most common GPS PPP techniques employ undifferenced ionosphere-free (IF) linear combination. In this work, both undifferenced and between-satellite single-difference (BSSD) IF linear combinations of pseudorange and carrier measurements are considered. IGS precise orbital and clock products are used to correct for satellite orbit and clock errors. Rigorous models are used to account for tropospheric delay, ocean loading, earth tide, carrier phase windup, relativity and satellite antenna phase-center variations. To integrate GPS PPP and MEMS-based inertial systems, the process and measurement models are developed. Tightly coupled mechanization is adopted, which is carried out in the raw measurements domain. Extended Kalman filter is developed to merge the corrected GPS satellite difference observations and inertial measurements and estimate inertial measurements biases and errors. A atlab-based computer program is developed to carry out the tightly coupled integration. The performance of the proposed integrated system is analyzed using a real test situation. It is shown that decimeter-level positioning accuracy is achievable with both undifferenced and BSSD integrated systems. However, in general, better positioning accuracy is obtained with BSSD integrated system.
