Geo-Wiki.org: Validating Global Land Cover with Crowdsourcing

The AGISRS list made me aware of Geo-Wiki.org, a crowdsourcing effort aimed at validating global land cover.

From their main page: "The Geo-Wiki Project is a global network of volunteers who wish to help improve the quality of global land cover maps. Since large differences occur between existing global land cover maps, current ecosystem and land-use science lacks crucial accurate data (e.g. to determine the potential of additional agricultural land available to grow crops in Africa). Volunteers are asked to review hotspot maps of global land cover disagreement and determine, based on what they actually see in Google Earth and their local knowledge, if the land cover maps are correct or incorrect. Their input is recorded in a database, along with uploaded photos, to be used in the future for the creation of a new and improved global land cover map."

  2. Geo-Wiki is a useful too that needs to be expanded and improved upon. I wrote a short blog post yeserday about crowdsourcing of social media as a validation tool for LULC maps: http://www.geoinformatic.org/20120208/crowdsourcing-social-media-to-validate-land-use-and-land-cover-maps/

  3. Isn't deriving information from Google Maps/Earth a violation of the Google Eula?
