Maps, values, information sharing (and Wisconsin) - 3 views

  •  
    Wisconsin is one of two states to have a "State Cartographer," and man does he have some interesting stuff to say. The interview here speaks to GIS software and technology, but also the broader perspectives on exactly what it is a map does, and how it does it. Particularly interesting when he speaks about values - every map has them, he says, they are not neutral parties. Is this true for other tools we have for conveying information?

Neighborhood gets high-tech outreach - 2 views

    An example of GIS in real life! Danielson Castillo is using geographic information system (GIS) mapping to layer several sets of data on a computerized map. The depth and breadth of the mapping project, completed last month, is unheard of on a community level in Minnesota.
    The project was funded with a $20,000 grant from the McKnight Foundation, but Danielson Castillo and Matson believe it's a tool that will become increasingly common and affordable for community organizations. Danielson Castillo already has given demonstrations of his GIS map to a number of community organizers.

Yale Environment 360: New Google Earth Technology Allows Tracking of Environmental Changes - 0 views

  •  
    We live in the age of data and here's another great application of our ever developing analysis tools. Very relevant to our ENVS 220 GIS unit.

New Maps Show Racial Segregation in Vivid Color - 2 views

  •  
    Looks a lot like GIS to me. But what's this? Not using a broad tract system to generate region averages, but instead more detailed and neighborhood specific system?
    These maps only show racial segregation, but its a promising basis for the improvements for which Davidson advocates in EJ analysis.

    Here's Portland's map: http://www.flickr.com/photos/walkingsf/4982015862/in/set-72157624812674967/

    This is an important and significant perspective. Compared to other cities, we're not working with a lot when we talk about diversity and segregation in regards to environmental justice. Comparing our EJ mapping to EJ mapping in cities with much more significant segregation would be interesting! (Who wants to do some more GIS mapping for fun over fall break??)

    This (http://www.radicalcartography.net/index.html?chicagodots) is Bill Rankin's website, the cartographer who first produced one of these detailed maps in 2009 and inspired Eric Fischer to produce all the others (found here: http://www.flickr.com/photos/walkingsf/sets/72157624812674967/with/4981417821/). Check out the downloadable files on Rankin's website (there's one for race and one for income); he includes includes a traditional GIS map of the same data for comparison. (I recommend saving them to your computer and viewing them at a smaller scale to see the patterns more easily.)

    This is from his website:
    "There are indeed areas where changes take place at very precise boundaries... But transitions also take place through gradients and gaps as well, especially in the northwest and southeast. Using graphic conventions which allow these other possibilities to appear takes much more data, and requires more nuance in the way we talk about urban geography, but a cartography without boundaries can also make simplistic policy or urban design more difficult - in a good way."

Water map shows billions at risk of 'water insecurity' - 1 views

  •  
    "About 80% of the world's population lives in areas where the fresh water supply is not secure, according to a new global analysis."

    This article addresses a new study published in "Nature" that is looking at patterns of global water stress. It weighs the benefits of the western approach (damns, canals, etc...) against more integrated, "natural" approaches such as preserving wetlands and floodplains. The centerpiece of the study is a great example of GIS mapping on a global scale.
