GeoRoundUp: Zombie Map, James Fee Brings Back Comments, Flying Over Planet Earth

Making the rounds is a quirky map created by Dr Mark Graham, Taylor Shelton, Matthew Zook, and Monica Stephens from the Oxford Internet Institute that maps out the concentration of Google searches for “zombies”:

[T]0 measure the amount of content about zombies indexed by Google, a dataset was created based on a 0.25 x 0.25 degree grid of all the land mass in the world (roughly 250,000 points). A buffer was then constructed for each point using a sliding variable size based on the great circle distance to neighbouring points in the grid pattern. It was important to adjust this value in order to compensate for decreasing distance between longitudes as the software moves from the equator to the poles. For each point and buffer combination a search was run in Google Maps to measure the total number of hits for user-generated content at each location (as defined by Google).

Not surprisingly, the map shows that searches for the word “zombies” is concentrated in areas of the world where English is widely spoken and the population is particularly dense (i.e. major cities).

James Fee, who runs one of the more popular GIS blogs (which incidentally was recently renamed as Spatially Adjusted (which now matches the URL), has turned comments back on (his original reasoning for turning them off in April was posted about here).  Personally, I’ve found that the at times lively commentary that tends to sprout up on his blog makes it one of the more interesting places to visit on the Internet for geospatial debate.  Visit: Spatially Adjusted

There is an amazing time lapse video (embedded below) showing the view of the earth from the International Space Station on YouTube.  The video, taken at night, shows the lights emanating from the cities of Portland, Seattle, San Francisco, Los Angeles, and Phoenix, to name a few.  The data used to produce the video was downloaded from the Gateway to Astronaut Photography site.
