Quick Installation Guide

From Zip Archive

We make regular releases of the InaSAFE plugin and they are available at Simply choose the most recent (i.e. the one with the largest version number) and save it to your hard disk.

Now extract the zip file into the QGIS plugins directory. Under windows the plugins directory is under :file:`c:\\Users\\<your username>\\.qgis\\python\\plugins`.

After extracting the plugin, it should be available as :file:`c:\\Users\\<your username>\\.qgis\\python\\plugins\\inasafe\\`.

Mac and Linux users need to follow the same procedure but instead the plugin directory will be under your $HOME directory.

Once the plugin is extracted, start QGIS and enable it from the plugin manager. To do this open the plugin manager (:menuselection:`Plugins --> Manage plugins...`) and type :samp:`insafe` into the filter box. You should see the InaSAFE plugin appear in the list. Now tick the checkbox next to it to enable the plugin.


Via QGIS Plugin Manager

System Requirements

  • A standard PC with at least 4GB of RAM running Windows, Linux or Mac OS X
  • The Open Source Geographic Information System QGIS ( InaSAFE requires QGIS version 1.7 or newer.


InaSAFE is a very new project. The current code development started in earnest in March 2011 and there is still much to be done. However, we work on the philosophy that stakeholders should have access to the development and source code from the very beginning and invite comments, suggestions and contributions.

As such, InaSAFE currently has some major limitations, including

  • Hazard layers must be provided as raster or polygon data
  • Exposure data must be either raster data or vector data but only point, line and polygon types are supported.
  • All data must be provided in WGS84 geographic coordinates
  • Neither AIFDR nor GFDRR take any responsibility for the correctness of outputs from InaSAFE or decisions derived as a consequence
