Most of my energy has been directed to paper maps and exhibition material of various kinds:
1, Here are some wall maps of Phoenix that I'm quite happy with; the goal was to push conventions about land management and social statistics in ways that ask new questions about stewardship and segregation. I presented these maps a few weeks ago as part of the "Remapping the Desert" series sponsored by the Future Arts Research program at Arizona State University.
2, In the May issue of National Geographic are some maps of mine accompanying an article about mapping and territorial claims in the Arctic Ocean. I've posted some unpublished studies of climate, oil, changing territorial claims, and revisions to the map of the Arctic seafloor. The biggest thing to notice here is that the traditional idea that countries are bounded by a "hard shell" of a single perfect boundary is being revised even as I type; under the UN Law of the Sea, there is now a feathered edge of different maritime rights at different distances from shore.
3, Another wall map, just for kicks: world railways! I'm also inching my way towards tackling a world map in earnest; this is my first foray into some of the thorny issues of distortion, continuity, and conventions at the global scale.
4, Last spring I renovated my maps of American agriculture for an exhibition at the Harvard Graduate School of Design; they're a big improvement over the old ones, not least because data from the 2007 census is a lot cleaner than the 1997 data. I also made a quick animation of world cropland since 1700 for the same exhibit, based on data from agricultural geographers.
