Metro Lens is a web app built to answer some of the questions I have most often about urban areas.
- How large is the area?
- How many people live here?
- How many cycling paths are there?
- How much car parking?
- How many bus routes? Train stations? Parks and recreation areas?
This app specifically answers all these questions on any arbitrary provided shape, scratching the urbanism investigation itch, a la CityNerd. See the examples below and compare your favorite city, or shame your most detested!
Try it here: metro.pelmers.com. For more details: My Blog post.

What will you discover?
The app presents a map, initially centered on a randomly selected large city. Click either the polygon or circle button to draw a shape on the button. Then see relevant areas highlighted on the map and the statistics table populated. You can customize various display options, such as changing between satellite and map views, or metric and imperial measurements.
