GIS - Qualitative variables

Dear all,

Is it possible to represent qualitative (or Boolean) variables at polygons level in the GIS App?

As an example, we are planning to use Event capture to ask some programmatic questions to the programme managers, who will answer at country level. We would like to produce maps representing in red the country which answers “no” and in green the ones which answer “yes”.

Event layer apparently works to plot points (not polygons).

Thematic layers apparently only supports quantitative variables, right?

So how do I do?

Sorry for this basic question…

Lise.

Hi Lise,

As far as I know, the only work-around right now is to code your qualitative answers as numbers (e.g. 0 = No, 1 = Yes, 3 = N/A), then create a legend set with corresponding ranges, see example below.

We’ve used this for aggregate data elements at country level, but would assume that it works if you create a thematic layer based on Event data elements. If that doesn’t work then you probably need to create indicators based on your event data before you can map out by polygon.

Hope this works for you!

Dear Bram,

Thank you very much for sharing this tip.

However, it seems it does not work with programs… Or at least I am still not able to map neither my OptionSet Yes/No/Unknown, nor my Yes/No questions, neither through data elements or through PI…

Anybody has experienced this before? Should be straightforward to map this kind of basic things….

Lise.
