Podcast delay

I am feeling a bit under the weather this weekend. The podcast should be up by Monday night. Apologies for the delay!

Water World

The BBC online has a story on a composite index of “water threats” including issues such as scarcity and pollution which researchers from City College of New York presented in the journal Nature. This is not the only water data project that City College of New York faculty and students have done this year. A “Bio-Math Mapping: Water Quality Analysis of the Hudson and Gowanus,” project in Summer 2010 provided math students with a chance to participate in interdisciplinary research with epidemiology, microbiology and environmental studies through a four-week investigation of water quality of the Hudson River and Gowanus Canal.

Mapping the Segregation of US Cities

The Atlantic Wire has a short piece about a series of maps by Eric Fischer detailing racial living in 40 of the largest US cities.  Unfortunately the maps are stored on Flickr as flat files, so it’s hard to zoom in and around to see more detail.  The basic method appears to get racial information down to the housing unit so it creates a point cloud of race within urban areas.  The interesting point of this method is that most cities aren’t hard delineations of race but a much more interspersed picture, despite the example from Detroit The Atlantic Wire uses.

If Google Maps Were Real

Mashable (perhaps one of the cooler sites I visit each day) has a nifty story about an artist who drew Google Maps icons as if they existed in the real world.  It’s rather interesting to think about these big push pins existing in real life, or a pop-up box over a building.  Take away the surprised looking people and I think we’ll have a pretty good idea of what large scale augmented reality is likely to look in the near future.

Episode 1 of the Geospatial Revolution Project is now out!

It’s a project we’ve been excited for ever since we first heard about it, and was great to be able to interview some of the Geospatial Revolution Project team, so it’s great to be able to post that Episode 1 is now live on the Geospatial Revolution Project website!

The full episode is jut over 13 minutes, but it’s also broken up into smaller videos via YouTube for those who can’t stream the whole thing. The team have also made the episode video shareable, so spread the word and to get you started, here’s Chapter 1 of Episode 1:

Visualizing Average Days Worked and Vacation by Country

I’m a big fan of infographics, so much so that I sometimes find seeing spatial information organized in an non-spatial way (ie a map) to be the clearest way to communicate an idea.  This infographic detailing average work week lengths and average vacation days is one of the ones I think really works.  The combination of a typical ‘graph’ along with some cute graphics really makes the thing accessible.  The data does have some holes, I think, because the ‘average work week’ seems to pull down a tad.  I’m assuming part-time work is included.  It’d also be interesting to see an economic variable in there, like GDP or per capita income.  Does working harder and longer get your more money?  And I have to admit, for all my talk about infographics, the next question I have is I’d like to see it on a map 🙂

Urbagrams – Mapping the social city

In order to investigate the idea of a social archipelago, the notion that our cities are “fragmented islands of social activity separated by large areas dedicated to commercial workplaces, flows of vehicles, residential sprawl or industrial sites.” Anil Bawa Cavia analyzed more than a million Foursquare check-ins in a number of cities and mapped those data as points to create a series of social activity density maps, which he calls urbagrams. By looking at the resulting maps for cities such as New York, Paris, and London, we can get a picture of the spatial distribution of social activity through Foursquare, and see where social activity is clustered and how the patterns differ from city to city.
