Barcelona is one my favorite cities in the world. I love the intimate laneways in the old part of town. I love how La Rambla functions as a spine for public life in the city–even if it is pretty touristy. I love the weather and beaches. And I love that there’s a strong culture of art and design that seems to permeate all aspects of the city. 

Over the weekend I found an impressive website called BIG TIME BCN, that beautifully maps out the city’s more than 2,000 years of building. It covers over 70,000 plots of land and, if you hover of them, it’ll tell you the age of the buildings. It’s similar to what was done here for the Netherlands. But the colors on this one seem very Barcelona to me.

I just came across an interesting web app created by geographer and programmer Andrew Hardin that maps public transit travel times for San Francisco, Seattle, Boulder and Denver.

The app allows you to click on a location within one of these cities (or enter an address) and then receive a visual representation of travel times from that location.

Both public transit and walking are factored in, and the fastest of the two is then modeled. The public transit data is taken from each respective authority and is similar to the data used by Google Maps.

With these sorts of applications, I always wonder what it might look like overlaid with additional data points, such as home prices. Intuitively I would expect the best connected neighborhoods to also have some of the highest real estate values.
