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 As a result, in many cases the datasets are out of date because of the high cost of maintenance.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

OpenStreetMap is a marvel of modern crowdsourcing. Since its creation in 2004, DIY cartographers – typically armed with GPS devices or satellite photography – have been slowly mapping the world’s road networks and landmarks to create a free alternative to proprietary geographic data that can then support tools like trip planners. The process, which began in the U.K., is painstaking and piecemeal, and nearly a decade into it, more than a million people have contributed a sliver of road here or a surveyed cul-de-sac there. …

On a hazy day last January, an unmanned aircraft enthusiast piloted his camera-equipped drone in the vicinity of a Dallas meatpacking plant, cruising around 400 feet in the air. To test his equipment, he took some photos of the Trinity River with a point-and-shoot camera mounted to his $75 foam airframe. When he retrieved the remote-controlled aircraft, he noticed something odd in the photos: A crimson stream, which appeared to be blood, leaking into a river tributary. …On Dec. 26, a grand jury handed down several indictments against the owners of the Columbia Packing Company for dumping pig blood into a creek. … Under a new law proposed in the Texas legislature, sponsored by a lawmaker from the Dallas suburbs, this type of activity could soon be criminal. …
Texas House Bill 912–and similar laws under debate right now in Oregon and elsewhere–are driving a burgeoning debate about how to use and control unmanned air systems, from an AR.Drone to a quadcopter. The Federal Aviation Administration is in the process of drafting new rules governing unmanned aircraft in civilian airspace, including military-style aircraft. But in the meantime, plenty of cheap, easy-to-use aircraft are already popular among hobbyists and, increasingly, activists and law enforcement.

In this week’s issue [of Science] (v. 333, n. 6046, Aug. 26, 2011), one of the seven featured publications is described in a paragraph entitled “To Catch a Quake” by Nicholas S. Wigginton (p. 1072). … Wigginton’s synopsis of the article describes the Quake-Catcher Network, “a volunteer-based seismic network that employs personal computers as low-cost seismic stations by sending seismic data collected with a small USB accelerometer through the user’s Internet connection.” After Chile’s huge earthquake in 2010, “volunteers rapidly installed nearly 100 accelerometers within weeks in and around the mainshock [sic] area.” …
