Hi Barcelona readers

If you're into BCN geo stuff please come along to GeomobBCN - our next event is on 6th of May, details here:

https://thegeomob.com/post/may-6th-2020-geomobbcn-details

Here's a twitter thread summary of our last event in January, lots of cool maps of Barcelona: https://twitter.com/geomob/status/1217706889280217089

I guess a significant part of HN readers are in the US; my sense is that most US residents are currently avoiding any trip to Europe for the next few months, due to the Coronavirus epidemic/issue.

I guess you won't get much interest for your event, in terms of attending in person.

Edit: not sure why I am being downvoted.

The message was addressed to "Barcelona readers", i.e. readers in Barcelona. But even if it hadn't been, do you think your comment would really contributed something helpful?

You are probably right; I originally thought that the message was to invite people from abroad to visit Barcelona, hence my skepticism about people wanting to travel there.

There are a lot HN:ers outside of the US and Barcelona is one of the more startup/tech-heavy cities in Europe.

There is an app called Urban Trees (https://urbantrees.app/) based on open data of several cities. With the app you get an AR view of the trees around you, with their labels etc.

They currently have data from Barcelona, Bristol, Clark County, Edmonton, Frankfurt, Las Vegas, London, Melbourne, New York, Paris, Portland, Rostock, San Francisco, Santa Monica, Seattle, Vancouver, Washington DC, Vienna and Zurich.

Is the data sourced from or published to OpenStreetMap? I note OSM does have ways to add individual trees:

https://wiki.openstreetmap.org/wiki/Tree

this is a great resource!

I visited Granada, Spain recently and learned from a guide how a particular type of tree is planted along Gran Via specifically to absorb radiation and pollution off the streets. I cannot recall the name for the type of tree.

I sure hope Urban Trees can expand to include more and more cities so that we can learn more about the plants in cities across the world and some of the interesting perspective on urban planning!

"Absorbing radiation and pollution" is magical, fact-free thinking.

Alas, iOS only!

seems a strange place to start. But indeed it does appear to not have an Android version.

50 years from now, will cities provide "APIs" for residents to query & access city data and services? will i be able to "REST" some "JSON" telling me when the tree around the corner that my dog likes best was last watered? i would love this.

note: "quotes" used because who knows what interfaces will be the saveurs du jour, then.

The average city is swimming in data these days. Many expose it through various APIs. The Socrata platform (disclaimer: I work there) is one example of many.

For instance, here's Edmonton's tree dataset: https://data.edmonton.ca/Environmental-Services/Trees/eecg-f...

API docs are here (there's an API button on the top right of the first linked page that takes you here): https://dev.socrata.com/foundry/data.edmonton.ca/eecg-fc54

Example query - 10 most recently-planted trees bearing edible fruit:

https://data.edmonton.ca/resource/eecg-fc54.json?$query=sele...

50 years? Try Iceland, right now. http://docs.apis.is/ APIs for gas stations, concerts, TV schedules, school syllabi...

Those Vikings are sure damn smart...

Thats great, gonna play around with that

My city (third largest in Spain) already has APIs for querying static and real-time data: http://gobiernoabierto.valencia.es/en/info-api/

My father owned a tree service in the town I grew up in. We spent countless hours driving around town, looking at different trees and giving estimates for trimming and removal. I could imagine leveraging this data as almost a Zillow for trees.

Lots of cities now have open data. Paris (France), for example, has both fixed datasets and real-time ones: https://opendata.paris.fr/

This is not "all the current trees in Barcelona", as the parks have no trees. I am fun at parties as well.

That was my first thought as well. Their main park, where the zoo is, has only the trees along the walk way defined. Maybe I didn't understand where this thing was supposed to be going.

Possible source of the data https://opendata-ajuntament.barcelona.cat/data/en/dataset?q=...

When I was in my early 20s (late '90s) I was lucky enough to spend a month in Barcelona with my future wife. It remains one of my all-time favorite cities in the world. I'll never forget walking its tree-lined streets to the sea.

Another Cool tree app is https://www.curio.xyz/world With lots of user tagged trees too

Same, for Amsterdam: https://maps.amsterdam.nl/bomen/?LANG=en

IIRC, many places (not all) in the world, tree density strongly correlates positively with property values. Does this hold true in Barcelona?

This is actually useful for finding parks.

No more than a regular map, as the trees in big parks don't have a mark: https://imgur.com/a/HIfFZTd

Even trees in small parks don't appear. I think the map lists only trees near streets.

not sure it's "current trees" as the dataset was created 5 years ago.

Barcelona's map will continue to shift over the coming years too, with its move towards 'superblocks'. Even within the space of a year since my previous visit, the block I used to live on was converted.

Likely we will see more trees and plants around those areas now the roads have been converted to open spaces.

What sort of architecture, housing and commercial uses are going into those converted areas?
