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 As a result, in many cases the datasets are out of date because of the high cost of maintenance.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.

In light of swiftly changing technical landscapes and increasing uses of social networking, the USGS is exploring a new approach to the volunteer program, and is launching a project to test options for volunteer participation in providing data to The National Map. The project involves mapping man-made structures and facilities, such as schools and fire stations, in the state of Colorado. Using an internet mapping application, volunteers can help the USGS update The National Map by correcting or adding information about structures. “Even members of the public who can’t tell a sandstone from a rhyolite but have internet access can now help the USGS keep its popular maps up to date through our new experiment in crowd sourcing,” said USGS Director Marcia McNutt. “Correctly locating and identifying fire stations, police stations, schools, and hospitals not only makes USGS maps more useful, but can literally save a life.”
Over the past two decades, the USGS National Geospatial Program sponsored various forms of volunteer map data collection projects. Volunteers helped the USGS improve its maps during this period, by annotating paper maps, collecting data using GPS units, and submitting data using a web-based tool. However, in 2008, the volunteer mapping program was suspended as new methods for using volunteer data were being studied. In recent years, new web- and mobile-based technologies have made it easier to create, combine, and share maps. Recent events have shown how well these technologies support the rapid and relevant production of geographic information. If the Colorado pilot project is successful in attracting volunteers and capturing data for use in The National Map, the program may be expanded to other areas in the future. This project offers volunteers an opportunity to participate in providing data to The National Map and US Topo map products. For more information, interested Colorado volunteers can visit the National Map Corps website.

“At the end of 2010, Matt Wilson (University of Kentucky) and Mark Graham(Oxford Internet Institute), started coordinating a special issue of Environment and Planning Adedicated to ‘Situating Neogeography’, asking ‘How might we situate neogeography? What are the various assemblages, networks, ecologies, configurations, discourses, cyborgs, alliances that enable/enact these technologies?’ My [Muki Hakly’s] response to this call is a paper titled ‘Neogeography and the delusion of democratisation’ and it is finally been accepted for publication. I am providing below an excerpt from the introduction, to provide a flavour of the discussion:
“Since the emergence of the World Wide Web (Web) in the early 1990s, claims about its democratic potential and practice are a persistent feature in the discourse about it. While awareness of the potential of ‘anyone, anytime, anywhere’ to access and use information was extolled for a long while (for an early example see Batty 1997), the emergence of Web 2.0 in the mid-2000s (O’Reilly 2005) increased this notion. In the popular writing of authors such as Friedman (2006), these sentiments are amplified by highlighting the ability of anyone to ‘plug into the flat earth platform’ from anywhere and anytime. …”

3. Workshop Description and Goals
This Friday workshop will summarize the main research findings of a 4-year Canadian GEOIDE project that looked at law, data quality, public protection and ethics in relation to geospatial data. The agenda is below. More details will be found on the GSDI-13 Conference web site shortly, including registration instructions. A small fee will be charged to cover out-of-pocket expenses. The workshop is open to the public.
