Compare GoogleMaps and OpenStreetMap

If you like map comparison websites, you will love this one !

GeoFabrik's Map Compare allows you to view several OpenStreetMap layers side by side with different Google Maps map types. The two maps are synchronised so zooming or panning one map will zoom or pan the comparison map. Geofabrik is the work of two active German OpenStreetMap contributors, and the Map Compare tool was developed to allow Geofabrik to compare OpenStreetMap map offerings to Google Maps maps and aerial imagery.

An interesting platform that I have discovered recently, after the Haiti and Chile events. It is good thing that such an open source initiative exists :

The Ushahidi Engine is a platform that allows anyone to gather distributed data via SMS, email or web and visualize it on a map or timeline. The goal is to create the simplest way of aggregating information from the public for use in crisis response.

Is Social Media a Fad ?

This video circulated several months ago but I feel I wanted to share it here. It is very nicely done and is a very good tool to use in a presentation for example. And for the non english native speakers : fad = fashion !
