[Termes IGN] personne en fauteuil-roulantRésumé : (auteur) The development of a wheelchair user friendly route planning application inherits a number of special requirements and details that need to be considered during the generation of the routing graph and the corresponding algorithm, making this task much more complex than car or pedestrian related applications. Each wheelchair type and, more importantly, each individual user might have different needs with regards to the way condition or other criteria. This study proposes a new approach to route planning for wheelchair users tailored for individual and personal requirements provided by the user and the calculation of a reliability factor of the computed wheelchair path. The routing graph is based on the freely available Volunteered Geographic Information (VGI) retrieved from the OpenStreetMap (OSM) project. The newly created algorithm is evaluated and tested for a selected area in Bonn, Germany. A new reliability factor is introduced that gives direct feedback about the quality of the generated path. Similar factor estimations can also be utilized for multiple route planning applications where VGI or other commercial or administrative data is implemented and more detailed factors than a simple geometric representation of a street network are of importance.

[Termes IGN] UkraineRésumé : (auteur) Although the European Geostationary Navigation Overlay Service is primarily designed to provide benefits from a space-based augmentation system that serves the European Union nations, it actually covers regions outside that geographic area. In this article, researchers tracking EGNOS signal availability in Ukraine conclude that its performance there is improving in robustness and reliability.

[Termes IGN] positionnement par GNSSRésumé : (auteur) This paper presents accuracy characteristics of determining the position of corners of building structures with RTN GNSS surveying, using indirect methods of measurement. The studies included the following methods: a point on a straight line, intersection of straight lines and distance-distance intersection. The research experiment analyzed the coordinates of the corners of building structures obtained from the surveys and the mean errors of their position as well as mutual relationships of check measurements, or tie distances. The accuracy analysis also took into account base errors determined in real time. Statistical analysis of these parameters was carried out, as a result of which a distance-distance intersection method was very well rated. For other methods, the results were diversifi ed. The article also emphasizes a need to search for other solutions to modernize the indirect methods of measurement in such a way that their use in RTN GNSS surveys would give results most probable when compared to the real ones.

[Termes IGN] validation des donnéesRésumé : (Auteur) Within our research of the Emergency GIS we have tried to extend the classic approach to the usage of spatial data within the emergency management with novel concepts of the user generated geo-content. Our goal is to include citizens into process of emergency awareness that will lead to better results in early warning and prevention of crisis events trough development of partnership between community and official emergency institutions and agencies. Therefore, we have developed a prototype of a mobile application for collecting georeferenced content in the field: EMdroid. It provides users with the ability to capture videos, images and sounds, or type text that will include the location data according to their actual position. The application also supports reliability assurance functionality that is based on the asynchronous push notification mechanism. Supported by proper emergency GIS infrastructure, users sending such data to Emergency Operation Center can provide critical information for emergency response and improve situation awareness of the emergency crews even before they are dispatched to the location of the emergency.

[Termes IGN] science citoyenneRésumé : (Auteur) Citizen science projects encourage the general public to participate in scientific research. Participants can contribute large volumes of data over broad spatial and temporal frames; however, the challenge is to generate data of sufficient quality to be useable in scientific research. Most observations made by citizen-scientists can be independently verified by “experts”. However, verification is more problematic when the phenomena being recorded are short-lived. This article uses a GIS methodology to verify the quality of contrail observations made by the general public as part of the OPAL Climate Survey. We verify observations using datasets derived from a variety of different sources (experts, models and amateur enthusiasts) with different spatial and temporal properties which reflect the complex 3D nature of the atmosphere. Our results suggest that ~70% of citizen observations are plausible, based on favorable atmospheric conditions and the presence or absence of aircraft; a finding which is in keeping with other, more conventional citizen science projects. However, questions remain as to why the quality of the citizen-based observations was so high. Given the lack of supporting data on observers, it is impossible to determine whether the dataset was generated by the activities of many participants or a small but dedicated number of individual observers.
