Extent of the Ravenswood City School District: Then and Now
This map depicts the strange, gerrymandered-seeming boundary that has developed between the Ravenswood City School District (comprised of the City of East Palo Alto and the northern portion of Menlo Park, California) and the adjacent Menlo Park School District, as neighborhoods to the southwest of a major freeway, US Highway 101, opted to leave the [...]
A Hand-Drawn Map of California
I completed this map in October 2012, just in time to exhibit it in the Map Gallery at the NACIS (North American Cartographic Information Society) Annual Meeting in Portland, Oregon. I spent a portion of most of my weekends from December 2011 to October 2012 working in earnest on the project, though I had developed [...]
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 the original post here. This is actually the second version of the map, after Asya and Martin solicited feedback from readers to correct errors and inaccuracies. Read about the revision here. The great circle route from London [...]
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, 2012 edition
In the spring of 2012, I completed edits for the 3rd edition of the City of Oakland’s Bikemap, which reflected about 14 miles of additional bikeways installed since the release of the 2011 edition. Read my design notes from original 2010 edition here. View the map on the City of Oakland website by clicking here (it’s [...]
