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 As a result, in many cases the datasets are out of date because of the high cost of maintenance.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

The International Organization for Migration (IOM) just published their official Data Protection Manual. … At the same time, the 150-page report does not mention social media even once. This is perfectly understandable given IOM’s work, but there is no denying that disaster-affected communities are becoming more digitally-enabled—and thus increasingly the source of important, user-generated information. Moreover, it is difficult to ascertain exactly how to apply all of IOM’s Data Protection Principles to this new digital context and the work of the Standby Volunteer Task Force (SBTF). …

People Protection Standards 1.0: Response by the Satellite Sentinel Project Team at Harvard Humanitarian Initiative to Recent Comments Concerning the Global Brief Article Entitled: Crisis Mapping Needs an Ethical Compass
by Satellite Sentinel Project Team, February 2012
When Raymond, Howarth, and Hutson wrote our argument for the development of comprehensive ethical and technical standards for the crisis mapping community, we were aware of last year’s meeting hosted by World Vision in Geneva and the 2010 meeting in Phnom Penh hosted by Oxfam Australia on Early Warning for Protection. … These efforts are laudable, much needed, and constructive. They are also by themselves insufficient to address the challenges that our field and those we seek to assist face as a result of the work we all do. While important initial steps, the meetings, protocols, and blog posts regarding these issues do not create a comprehensive code of ethics and technical standards by themselves. The issue is not whether there have been meetings or working groups. The issue is whether the crisis mapping community will decide to self-regulate in a proactive way before serious lapses by any of us put civilians in jeopardy. …

Tribes in Southeast Asia are being kept from using the latest high-tech gadgets to help them win land rights. That’s the outcry from activist groups that have been helping indigenous communities mix computers and handheld navigation devices with paints, yarn, and cardboard to make simple but accurate three-dimensional terrain models. … But in Malaysia and the Philippines, the practice—dubbed participatory GIS—has sparked a legal backlash, activists say. For example, Philippine lawmakers have changed an existing law so that only officially recognized engineers “could do anything related to measuring space,” said Dave De Vera, director of the Philippine Association for Intercultural Development. …
