@slowe@mastodon.me.ukSimilar to our population calculator, we also make the Parkulator https://open-innovations.github.io/parkulator/ It is a tool which finds all the car parks (parking lots) within an area (from OpenStreetMap) then estimates alternative things you could do with that land such as build homes, build parks, or generate solar power.
For instance, Leeds is 0.73% carparks (402.70 hectares). On that we could build roughly:
40,200 homes at London density;
120,800 homes at Paris density;
201,300 homes at Barcelona density;
610 parks like Park Square, Leeds.
That area could generate as much as 199MW (equivalent to 59,700 homes) from solar power.
Having so much requirement for parking (and this doesn't include all the on street parking) stops other things being possible.
@slowe how many Richard IIIs is that though?
@Floppy Does each Richard III need a whole car park?
@gilesdring @slowe @Floppy what about this in Desmonds?
@slowe I really wanted to try it in the US but it failed on Indianapolis (which I remember as mostly car parks with some buildings around them)
@mia Hmm. It looks as though some of my pre-defined areas are broken. I'll have a look at that. In the mean time, you could try drawing a boundary as the second step (loading parking lots from OpenStreetMap) still works there.
@mia Oh. I was wrong. Now that I'm at a computer it turns out there are some weirdly defined car parks in the Indianapolis area which broke my code. Hopefully it is fixed now. You may need to hard reload the page to avoid your browser using a cached version.
Thanks for spotting this!
@slowe thanks for making the site! It's very cool
