New Research on Legal Issues and Validation of Crowdmapping

Rak, Andriy (2013). Legal Issues and Validation of Volunteered Geographic Information.

Abstract: The Canadian Geospatial Data Infrastructure (CGDI) provides access to authoritative geographic datasets of Canada, which 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. As a result, in many cases the datasets are out of date because of the high cost of maintenance. An alternative approach to reliably create and update authoritative datasets is linked to its integration with Volunteered Geographic Information (VGI). VGI provides a vast source of spatial information to government, industry and citizens. However, the integration of VGI with CGDI generates several questions, with VGI quality and legal issues at the forefront.

This research has investigated methods for assessing the quality of VGI, and describes the importance of a link between VGI and legal liability in the need for integration of VGI with CGDI. This research developed a prototype to validate data quality and examined legal liability issues around VGI to discover a strategy for possible integration of VGI with CGDI datasets. The research also provides four primary risk management techniques for CGDI to manage risks resulted from incorporating VGI into their datasets.

NYT: World Bank Is Opening Its Treasure Chest of Data

by Stephanie Strom, Global Business Section, New York Times, June 2, 2011

Those data sets contain all sorts of information about the developing world, whether workaday economic statistics — gross domestic product, consumer price inflation and the like — or arcana like how many women are breast-feeding their children in rural Peru. … For whatever its accuracy or biases, this data essentially defines the economic reality of billions of people and is used in making policies and decisions that have an enormous impact on their lives. …
