[GeoForAll-UrbanScience] Ideas on spatio-temporal analysis of air quality point data

[Hogan, Patrick (ARC-PX)]

Charlie,

Interesting. Where’s the data? If we could see it, it might be easier to figure out what to do with it and how to do it.

Bruce Schubert’s WMTweb app, the Europa Challenge winner for the ‘Professional’ track (http://eurochallenge.como.polimi.it/projects2015), has a lot of sophisticated spatio-temporal analysis and visualization techniques to it.

Maybe they could be rigged for this data. http://emxsys.com/

Subject: [GeoForAll-UrbanScience] Ideas on spatio-temporal analysis of air quality point data

Hi OpenCItySmart colleagues,

As a GeoForAll thematic sub-community, I'm posting this email in part to investigate whether we can start to move toward more substantive dialog around interesting research puzzles we are having. If anyone disagrees with this idea please say so -- we are building a community culture here. So here's a question a student and I are encountering. I'd like any ideas from colleagues on this list on QGIS-related analysis:

A public health colleague of mine has taken air quality samples (5 second intervals) over 2 weeks in six locations in a city in Asia and measured two public health contaminants. I have a student trying to use QGIS to analyze these data. We want to understand the spatial-temporal patterns in this data (where/when there are particularly dangerous levels, and where/when there are not).

Are there spatio-temporal analytic or visualization techniques in QGIS or related extensions we should investigate? Or if anyone knows of any papers that describe a technique we should look at, please advise.

Thanks!

Charlie

P.S. Our grant proposal to US NSF is still under review. Is anyone else working on any relevant proposals to move our community forward?
