Project: InaSAFE

Version: 4.0.0

Feature: Added support for analysis in irregular areas

In previous versions of InaSAFE, analysis was always carried out in rectangular areas. This has limitations - in particular that analysis results reported may not reflect the area of interest well. In InaSAFE 4.0, it is possible to use the polygonal outline of the aggregation area to constrain the analysis. This means that exposure features and population outside the aggregation areas will not be counted as part of the total counts, which makes the reporting more relevant for disaster managers trying to understand potential impacts.

Another key feature in irregular area support is that you can now select one or more districts using the QGIS selection tool - the analysis will only be run on the selected districts. Click play on the accompanying screencast to see how this feature works in action.
