Mappers Count All 43,123 Swimming Pools In Los Angeles

Someone decided to create an atlas dedicated to that iconic symbol of the good life in Southern California: swimming pools.
German graphic designer Benedikt Gross told Wired he was fascinated by the pools of Los Angeles ever since he flew on a plane over the city, "I was flying in for a study trip during the first year of my Royal College of Art degree, and I saw all these swimming pools. It looked like there were millions. It was crazy."
So later he went to work with a partner Joseph Lee of MIT to find out just how many there were and what they could tell us about the landscape. The pair worked to create what eventually became The Big Atlas of LA Pools. It turned out to be pretty easy to find out where the pools were and even grab snapshots of some of the pools themselves. (Compiling all that data is another story—they outsourced some of the tedious work to a company in India.) The result is an atlas that is 6,000 pages and comes in 74 printed volumes, according to the Los Angeles Times. There's only one copy.
The pair overlaid the data with a bunch of other data sets and here's what they found:
Here's a spin through one of the data sets:
At LAist, we believe in journalism without censorship and the right of a free press to speak truth to those in power. Our hard-hitting watchdog reporting on local government, climate, and the ongoing housing and homelessness crisis is trustworthy, independent and freely accessible to everyone thanks to the support of readers like you.
But the game has changed: Congress voted to eliminate funding for public media across the country. Here at LAist that means a loss of $1.7 million in our budget every year. We want to assure you that despite growing threats to free press and free speech, LAist will remain a voice you know and trust. Speaking frankly, the amount of reader support we receive will help determine how strong of a newsroom we are going forward to cover the important news in our community.
We’re asking you to stand up for independent reporting that will not be silenced. With more individuals like you supporting this public service, we can continue to provide essential coverage for Southern Californians that you can’t find anywhere else. Become a monthly member today to help sustain this mission.
Thank you for your generous support and belief in the value of independent news.
