|An example of Crowdmap: Haiti Earthquake internally displaced persons (IDP) camps|
Crowdmap is a neat little yet powerful tool which allows users to make their own intensity maps for free. The tool is completely online and does not require any downloading. These sorts of intensity maps became popular during the Haiti earthquake and recent conflicts like the last Israel-Hamas War.
It is easy to categorize data entries. A timeline tool is also available for one to add a temporal dimension to the spatial data. However, what truly seperates Crowdmap, and its earlier incarnation Ushahidi, from other tools is that it combines elements of Web 2.0 to allow for instant updating via crowd sourcing (imagine neogeography meets the open contributor policy of Wikipedia). Updates can be submitted by text messaging, Twitter, or filling out a web form.
The learning curve is extremely shallow and setup is down within minutes. Check out Vote Report India or Swine Flu for examples of what one can do with this powerful neogeography tool.
