Description: Virtual Globes environments, such as Google Earth, have drastically changed the context within which geospatial data are used. While geospatial data were often restricted to expert users, the general public is now increasingly in contact with geospatial information for different types of uses, without having the technical expertise to understand its characteristics, and hence limitations properly. Much of the uncertainty inherent to geospatial data is unknown to the user. Depending on the use to be made of the data, the uncertainty could cause undesirable outcomes or unreliable results. This research will focus on methods in which data uncertainty can be visualised in 3D virtual globes environments. First, an inventory of the ways in which geospatial data uncertainty can be visualised will be made. An inventory of the types of uses made of virtual globes will also be done. Then, a theoretical framework will identify the optimal methods that can be used to visualise uncertainty in virtual globes. The approach will be tested using a dataset which contains different types of uncertainty, to investigate and assess which of these methods best communicate uncertainty to non-expert virtual globe users. This will be done through surveying groups of non-expert users and analyzing the results.

Description: To satisfy the increasing needs for geospatial data quality management in the field of civil aviation, a research project has been started in Spring ’09 in the Department of geomatic sciences at Laval University (Québec City) with the collaboration of ICAO (the International Civil Aviation Organization), Transport Canada and Groupe Trifide.

The International Civil Aviation Organization, a UN Specialized Agency, is the global forum for civil aviation. ICAO works to achieve its vision of safe, secure and sustainable development of civil aviation through cooperation amongst its member States. Its mission aims to produce standards and facilitate compliance with these standards by its member States.

ICAO wishes to make available to its members a code of good practices dedicated to the design of a system in quality management for the production of maps or aeronautical databases. Hence, ICAO could make available to its members a tool to implement a quality management system which best fits each of their production system. Besides, such a system would be design to minimally meet the standards for ISO 9000 and ISO 10005. Thus, after having established this system, those countries could have the opportunity to obtain such an accreditation to ISO standards.

This research project will also include the implementation of a risk management method embedded into the development of the quality system, which is an innovative element in relation to past works. Note that this project is partially funded by the Networks of Centres of Excellence GEOIDE (project IV-23) and the Natural Sciences and Engineering Research Council of Canada (NSERC).

Description: Authoritative datasets, Volunteered Geographic Information (VGI) and other sources of spatial information collected by industry and citizens can be used to spatially enable government and society. Authoritative geographic datasets are the source of accurate and reliable data. The process of acquiring, updating and maintaining such datasets using traditional approaches requires both time and costly resources. An alternative and possibly more economical approach to reliably creating and updating authoritative datasets involves the integration of VGI. Such potential integration of VGI with authoritative datasets raises important legal considerations. Liability is a primary issue that can deter organizations from incorporating VGI into their datasets. Due to the lack of research on this topic, organizations consider it to be a better practice to exclude VGI as a viable option. In the view of benefits that VGI can bring it is important to continue and deepen the research on liability concerns surrounding VGI, so that organizations will not fear to face the legal liability risks that can arise and will be equipped with appropriate techniques to manage such risks.

This presentation will investigate the liability effects of using VGI under Canadian law. The questions of who is liable and when for VGI provided to authoritative public and private geographic datasets are among the most important questions which impact VGI, and are the ones which this paper aims to address. Liability issues of using VGI are studied by examining the liability in contract, as well as tort. To minimize and/or eliminate liability, in most cases, requires organizations to develop a risk management plan (Martinez, 2003). This paper concludes with liability risk management techniques which, if incorporated properly, provide opportunities to minimize or eliminate the liability.

Issues of legal liability arising from creation, distribution and integration of VGI with authoritative datasets have received very limited attention by scholars and researchers at their work. Further research is required in order to overcome shortcomings in the studies concerning legal liability arising from usage of VGI.

Description: En 1992 le gouvernement du Québec a mis en oeuvre le Programme actuel de réforme du cadastre québécois dont les objectifs sont de (1) constituer une image complète et fidèle du morcellement foncier, (2) d’assurer la mise à jour constante du cadastre et (3) d’assurer la polyvalence du cadastre. En 1994, parallèlement avec la mise en vigueur du Code civil du Québec, les travaux de la réforme du cadastre québécois ont commencé.

La recherche vise l’étude des risques encourus à utiliser les données issues de la réforme du cadastre québécois, le cadastre du Québec, et plus particulièrement à identifier les risques et impacts, associés au problème de qualité de la représentation cadastrale de l’objet du droit et à l’incertitude inhérente aux données cadastrales. L’objectif principal est d’identifier les risques associés à l’utilisation des données du cadastre du Québec lors de transactions immobilières et d’opérations de délimitation.

En plus de réaliser une recherche de niveau doctoral, les résultats suivants sont escomptés, soit de (1) concevoir un guide qui aidera les professionnels du droit foncier à adopter un comportement prudent et diligent en matière d’utilisation des données cadastrales issues du cadastre du Québec et (2) favoriser l’évolution des pratiques professionnelles liées au droit foncier et conséquemment, une sécurisation accrue des droits fonciers et une meilleure protection du public.

Description: The geospatial information is an essential element of any project planning. These data and information, those owned by public entities (State agencies, local authorities, persons entrusted with public service mission …) are exceptions, public data.
It is clear today that the use of geospatial data is essential in the areas of joint planning and the environment. It is then that practitioners are confronted with legal issues for which legislation is inappropriate or nonexistent, or sometimes at odds with other legislative and regulatory sources.
But this legal arrangement operates substantially in recent years to meet the expectations of producers and users – professionals, individuals and institutional – in which social, economic and legal require the establishment of a specific regulatory framework for these data.
Faced with such challenges and the risks related to the increasing use of geospatial information in public planning, the objective of this thesis is to pay particular attention to a burgeoning concept : the public domain geospatial. This whole discussion should help define legal status and expose a specific regime of eminent domain geospatial public.
