Does anyone know if Processing is being used for geospatial visualization? I can't find much out there, but this is impressive: http://benfry.com/zipdecode/

Here's one I just found: http://fathom.info/projects/countyhealth.html

  • This suggests it has been tried: forum.processing.org/topic/…

  • hahaha.That was me asking. Nobody helped. Nevertheless, after some self inflicted pain (I hate Java) I got it working perfectly fine. Ask away, although by now you probably already figured it out :) Feb 7, 2012 at 17:55

Some examples:

I've seen a lot of others like these--do you mean to ask about a more specific kind of visualization?


UnfoldingMaps is a library for map display, map interaction and geovisualisation for Processing.

Some examples here: http://unfoldingmaps.org/

  • those example visualizations are beautiful! Feb 7, 2012 at 17:57

giCentre @ CITY University London has created geoMap. It's quite young project but there is some documentation available and code samples.

enter image description here


I had a small question. I actually would like to build an application which is very similar to( http://tillnagel.com/2011/06/tilemill-for-processing/ ) but as a map and not on “Multi touch Table Top”.

The functionality I need is

Plot different cities of California with different radius, the different radius will represent number of times a person has visited a city.

When a person clicks on a city e.g LA it should show plot a polyline to different cities which are nearby. As shown in the link above.

I was wondering if you could help me on this, if you could give me a right direction to start with will be real great.
