Post-processors

This document explains the purpose of post-processors and lists the different available post-processors and the requirements each has to be used effectively.

What is a post-processor?

A postprocessor is a function that takes the results from the impact function and calculates derivative indicators, for example if you have an affected population total, the Gender post-processor will calculate gender specific indicators such as additional nutritional requirements for pregnant women

Selecting a post-processor

Post-processors and their settings can be edited in the user configurable function parameters dialog. See Setting Analysis Parameters to find the correct buttons. To disable a post-processor simply go to the Postprocessors tab and enable or disable any post-processor you like by clicking on the checkbox next to it. You can even set the postprocessing values you like here by entering the values in the fields. The same is valid for any other setting you might encounter there. If you don’t see a post-processors field, it means that the impact function you are trying to use does not support any post processor

Post-processor configuration

Post-processor configuration

Each activated post-processor will create an additional report in the dock and in the printout. If problems arise while post processing, the system will inform you and will skip post-processing.

Creating post-processors

If you feel there is an important post-processor which is missing, there are two avenues you can follow:

  • You can develop it yourself or with the aid of a programmer who has a good understanding of the python programming language.
  • You can file a ticket on our issue tracking system, and if time and resources allow we will implement it for you.

Contact info@inasafe.org for more information. Source code available on GitHub! Please file a ticket if you have discovered an issue.
