Population Density along Transit Lines: A Comparison
Martin Lewis of GeoCurrents commissioned this set of maps comparing two Bay Area rail transit lines—the Bay Area Rapid Transit system’s SFO-Pittsburg/Bay Point line and the Caltrain commuter line—with similar lines in the eastern United States (Washington D.C.’s Orange line and the Main Line in Philadelphia, respectively). I decided custom line graphs would provide additional [...]
Language Map of the Caucasus
Developed with Stanford linguistics expert Asya Pereltsvaig and Stanford History professor Martin Lewis for the GeoCurrents blog. Read more here. The great circle route from London to Mumbai passes directly over Tblisi. This map was also developed for the GeoCurrents series on the Caucasus region.
Cartogram: Purchasing Power Parity per capita
This is a cartogram I developed that resulted from a collaboration with Stanford History professor Martin Lewis and Anne Fredell, a research assistant at the Spatial History Project. I employ the Gastner-Newman method, using a cartogram tool available for ArcGIS desktop.
The BART System That Never Was
My Master’s thesis research explored the unlikely second wave of rapid transit planning that occurred at mid-century in the United States. One of those plans, from 1956, proposed a massive rapid transit system for the nine counties of the Bay Area. This transit diagram imagines what the Bay Area Rapid Transit system might have looked [...]
A Century of Growth: California Population by County
This post exhibits the first version of a cartogram of California population growth completed May 2008. I would later animate this cartogram using Flash. The Bay Area Automated Mapping Association awarded this subsequent dynamic version 1st place in its annual student map competition, in 2009. The cartographer Borden Dent describes cartograms as thematic maps that “are [...]
Oakland Bikemap, 2011 edition
In the spring of 2011, I completed edits for the 2nd edition of the City of Oakland’s Bikemap, which reflected about 10 miles of additional bikeways installed since the release of the 2010 edition. Read design notes from 2010 edition here. View the map on the City of Oakland website: side 1 (west) and side [...]
