This being a China blog, I don’t intend to dwell on non-China topics, but since I went through the trouble to establish a “masses and voids” category, I thought I would throw up these images as well.
These are from a project to study the areas around five subway (MUNI) stations in San Francisco, beginning in the Van Ness area (near downtown) and extending south and west into more residential and suburban neighborhoods.
The masses and voids images help show the density of development within a quarter mile radius of each station, indicating whether the station is within walking distance of an adequate number of residents or workers. You can see how big building footprints dominate the area around the Van Ness station, followed by very dense urban neighborhoods around Church (was has a large supermarket) and Castro. Forest Hill and West Portal are also residential areas, but befitting their relative distance from the city center, the building density there is lower – see how much more white space there is?
(People familiar with San Francisco neighborhoods can hover over the image to see the name of the station. You can click on the image to view a larger version, but using the arrow button to move to the next image isn’t a clean transition, so it’s better to view them side by side).
