I have been working a lot in Indonesia this year on the InaSAFE
project. InaSAFE is a QGIS plugin (also available as a web extension for
GeoNode) for assessment of scenarios following a natural disaster
such as a flood, earthquake, volcano, tsunami etc. This month the
InaSAFE team (which consists of developers from around the world, funded
by AUSAID and The World Bank / GFDRR) launched version 1.0 of
InaSAFE - which involved a phenomenal amount of work from everybody on
the project. The 1.0 release was made at the AMCDRR, a high level
conference for disaster risk reduction in Asia, and was even
demonstrated to the President of Indonesia which was a great feather in
the cap of QGIS and InaSAFE.
You can get your copy by simply opening QGIS (1.7.4 or 1.8), clicking
Plugins -> Fetch Python Plugins, then type 'inasfe' in the filter box
and select InaSAFE 1.0 from the list provided. InaSAFE is completely
Free and Open Source (GPL v3) and you can get source code from our
github project.
