TLDR
It is found that online tools, led by the Google Earth virtual globe, are changing the way the authors interact with spatial data, and will have far reaching implications for the way that scientists use spatial data.Abstract:
Life happens in three dimensions, so why doesn't science? Declan Butler discovers that online tools, led by the Google Earth virtual globe, are changing the way we interact with spatial data.read more

Citizens as sensors: the world of volunteered geography
TL;DR: In recent months, there has been an explosion of interest in using the Web to create, assemble, and disseminate geographic information provided voluntarily by individuals as mentioned in this paper, and the role of the amateur in geographic observation has been discussed.
Journal ArticleDOI
Participatory GIS : a people's GIS?
TL;DR: In this paper, a review of the role of community participation in GIS is presented, focusing on the control and ownership of geographical information, representations of local and indigenous knowledge, scale and scaling up, web-based approaches and some potential future technical and academic directions.

Geo-Wiki.Org: The Use of Crowdsourcing to Improve Global Land Cover
Steffen Fritz,Ian McCallum,Christian Schill,Christoph Perger,Roland Grillmayer,Frédéric Achard,Florian Kraxner,Michael Obersteiner +7 more
TL;DR: The Geo-Wiki Project is a global network of volunteers who wish to help improve the quality of global land cover maps, and volunteers are asked to review hotspot maps ofglobal land cover disagreement and determine, based on what they actually see in Google Earth and their local knowledge, if the land coverMaps are correct or incorrect.

Studying the global distribution of infectious diseases using GIS and RS
TL;DR: Analytical tools that are based on geographical information systems and that can incorporate remotely sensed information about the environment offer the potential to define the limiting conditions for any disease in its native region for which there is at least some distribution data.
Journal ArticleDOI
Mashups mix data into global service.
TL;DR: This is the future for scientific analysis: using big data to solve puzzles and provide real-time information about how to solve problems.
Journal ArticleDOI
Eye in the sky.
TL;DR: A small group of epidemiologists is abandoning pen and paper for digital maps with multiple dimensions to track infectious disease outbreaks, taking stock of a field in transition.
