How can I visualise data on OSM?

Posted by Badagarang on 19 December 2013 in English (English)

I have a range of (Australian) post codes and some values assigned to them, e.g.

postcode,value
2000,81
2001,2
2007,10
2009,5
2010,31
2011,10
2013,1
2015,4
2016,6
2017,8
2018,8
2019,18
2020,11
2021,6
2022,49

I'd like to visualise this data on OSM in different shades of colour. Is that possible and if so how?

So, you'll want to grab a piece of software called TileMill, and the ABS 2011 postcode boundary set, in all likelyhood.

Tilemill will let you make a stylesheet and preview your images, as well as add in basic data.

Thanks, CloCkWeRX. I downloaded and installed TileMill and had a look on the ABS site for the postcode boundary set, but couldn't find it. Any idea where it is? Is it free, or for purchase only? I'm doing the mapping as a private project only, so can't spend much.

Only thing is it's 2006 data and I don't quite know how to link the data with the CSV file I have.

I just figured out that I'll have to add this to colourise the postcode areas:

#poa06aaustregion::fill[zoom>=0] { [POA_2006='2000'] { polygon-fill:#ff0000; } [POA_2006='2006'] { polygon-fill:#00ff00; } [POA_2006='2007'] { polygon-fill:#0000ff; } [POA_2006='2008'] { polygon-fill:#990000; } [POA_2006='2009'] { polygon-fill:#009900; } }
