Web based mapping platform GeoCommons launched it’s 2.0 version yesterday. GeoCommons is the internet service where users can share, transform, visualize and mash-up geograohical information.

Why to use?
GeoCommons is a online free application that allows to use some of functionality of traditional GIS desktop software. It allows to:
- design, make and visualize multi-layer maps
- perform temporal visualization
- share over popular platforms like Facebook, Twitter ect.
- embed maps on a blog or website
- geo-coding (by uploading CSV speadsheet)
- convert data (e.g. Shapefile to KML !!! )
- filter geographical data
- open access to geographical data
- access open API for developers
And what’s best about it. You can do it in 10 minutes!!!
One need to stated as well disadvantages of the project. Fist of all the unknown accuracy of the data uploaded by users and other sources such as government agencies or non-governmental organizations. The only way to estimate accuracy of the data is to rate it, which for many purposes is basically insufficient. Secondly the data uploaded by users are open to others, so performing some business analysis is impossible.
Although there are pros and cons the tool is definitely worth exploring.
