I'm Ilya from Estonia. I like doing many things. I like bicycling. In Estonia, it's usually like this.
That's not me. But it's really fun. You should try. I also have maps and I collect data from maps everywhere.
I have map this campus already. It's a bit today. I'm making well bicycle on bicycle.
When I move to a new area in my city, I usually get up my phone.
And I start serving like local shops for groceries, local restaurants.
Like where our pharmacies are and stuff like that.
So I want to know what's around me.
So that when I need groceries or when I need to go to the theater, I don't have to drive all the way to the city center.
We didn't look at this fun because you can walk, you can ride a bike, you're not depending on anything.
And there is an info that. And this is a concept that has been growing popularity over the last five years.
And it's called usually called 15-minute city.
What is 15-minute city? It's pretty simple. Everything you need for a daily life should be inside 15 minutes of walking.
Just one American mile.
So who of you live in such a place that everything inside 15 minutes? Like do you know that?
Well, if you have, I expect it more. I expect it to be from Western Europe.
Yeah, not everyone, but a lot of people.
So this looks nice. This must feel nice.
Like, and somehow cities are not doing that.
But the idea is pretty old, 15 minutes city. Everything should be nearby.
It's the idea has come since 60s, I think.
And recently, they have been popularized by Karlsmarina, who is a advisor to Paris City, which, as you know, is a four-front of 15-unitizing cities.
But generally, it was academic research and social studies.
Like that, until something happened five years ago, when people found out they cannot drive to the grocery shops anymore.
So what was a nice 10-minute drive became one-hour walk.
And people thought, that's not ideal.
Like, walking to grocery shopping, take this much time.
And public demand for making our cities local, it started to grow.
And it started to get popular. In 2020, the idea of 15-minute cities appeared in all the mainstream media.
Everyone should know about that.
And it even got into many cities like strategic plans.
Paris is most known and many others.
Like, you can see how it works even here in Brussels, where how the streets are bicycle-first.
It's like reached everywhere. And of course, it reached my town as well.
My town is like in Eastern Europe, it's not very 15 minutes.
But it wants to, I guess.
In September, we celebrate so-called car-free day.
Well, everyone in the world probably said it was.
And we had in our city district a planned public discussion.
Should our district be 15-minute city?
And when I read about that in Facebook, because politics happens in Facebook or some reason,
I thought that's a great idea to have public discussion.
But for that, we need to have something to discuss.
We need to have some materials.
Are we already 15-minute city just nobody knows it or what doing it to do?
I'm a cartographer, so I'm looking for maps.
I want to make a map to publish on Facebook, so everyone can discuss that.
And not just some abstract ideas about it in the cities.
So, I'm also a laser cartographer.
So, I don't want to do this.
It always starts from that. I don't want to do this, right?
So, I'm looking for private art.
Because five years this concept has been very popular.
Everyone has been doing it.
Just personal data analysts has been doing it.
Because 15-minute city is like the tasks self-described.
15 minutes walking from all the points of interest.
You have it right there.
Just around the code.
There are multiple examples.
When people have done exactly that,
the middle one is like a big scientific publication with lots of articles like surrounding it.
So, I thought, yeah, should use it.
And they look legit.
Here's Marker.
And here portal just finds all the POI.
Not very useful for my case, but still it looks nice.
There's a Sony research lab work that's really great.
You choose the city and it's like split it in hexagon and shows like how far you should go for any hexagon.
And there's another one that makes like kind of heat map,
but also depending on like accessibility of things.
And you can see the pattern that first those are very pretty.
Like if I wanted to attract attention,
publish something, I would publish those images.
And second, they're not practically useful.
Like there are no action points you can derive from that.
You can just look at the pretty picture.
And you know, it's not great even here, right?
I wouldn't.
That's the only action point I can get from this.
If you live here, move there.
How do I improve my city district with that?
I don't know.
Yeah, there are weights, but if you start playing with weights,
you're starting to think, isn't this just a bad map of transport stops
and education facilities and not a 15 minute map?
So, yeah.
And also, where do they get the information about light clubs and parks and stadiums and restaurants and stuff?
Of course, they get it from open street map.
And getting points of interest from open street map is super hard.
I have made two presentations, exactly on that, in which I gave ideas,
but it's all very fuzzy, because all the texts are mangled.
So, I don't actually trust that.
So, yeah, our city council, of course, has 15 minutes maps themselves.
But I look at this map, it looks pretty, it looks, I don't know why they need it,
because some red yellow areas, this is a lake.
This is a bog.
This is a cemetery.
I don't know why they need like 15 minutes for that.
And even the blue areas, like, I know that this area,
there are, it's like 6 and 5, there are no grocery shops nearby.
People, I know who live there, they get into the car and they drive to get groceries.
This is not actionable.
This is a pretty picture.
Let's pretty then.
But, so, yeah, I didn't want to do it.
But, here I am to present my 15 minutes city script.
I'm really sorry, because we, as an open source,
community, have to redo everything by ourselves.
It's about everything, about social network,
passengers, office, software, 15 minutes creeps,
beacons, everything.
How do you come to this?
But we can do this.
This is a part when I plan to do some live demonstration,
and I have a backup.
So, but, yeah, why not?
I think we don't actually have time to do that.
We have time to do live demonstration, right?
Because we have like 5 minutes.
So, I have a backup talk, backup slides.
So, imagine I'm typing, you know,
and waiting awkwardly for things to complete,
but this, where I can just tap a button.
How do you do 15 minutes city with the script?
Super easy.
We have all the data available, all the software available.
This is a celebration of open source, not exactly a tutorial for making.
Like, we have open sheet map.
That's amazing.
Like, the single best projects, I know.
There are geofabric extracts.
You choose a city, your city, go to geofabric,
download your city from the portal.
Works awesome.
Then you go to some website, like,
for bounding boxes, Google it,
and cut your city from the entire country, download it.
So, here I chose,
how it's called,
Belgium City of Bruge,
and central Bruge.
Of course, it's full of points of interest.
It's no use making 15 minutes city map for city centers, right?
So, I choose some outskirts, called Assebroic.
And use Osmium 2, Osmium,
great tool for processing of the map data.
Two cuts of the city, just two megabytes.
Awesome.
Then to my tool,
some kind of configuration.
I can specify which layers do I need,
which text do I need,
because this is complex stuff,
when you know open sheet map.
If you don't, you can leave it to this.
And the most important thing is relation,
because in open sheet map there are relations,
which mark boundaries of cities and districts.
So, we can have not rectangular boundary,
but it will be nicely format,
it's district boundaries.
You can publish it and people will say,
yeah, this is local.
This is, you can believe it.
And, yeah,
I do first pass with my script.
I extract points of interest,
P.I. and buildings from the file we downloaded.
Why do you do I need this?
Remember that map that had like 15 minutes,
15 minutes accessibility for lakes,
and cemetery, we don't need that.
We need to know where people live,
and how life is for them,
not for zombies, I don't know.
So, we extract all the buildings,
probably miss there are buildings and cemeteries,
because in open sheet map they map everything.
They map every single shed.
So, I run QJS, which is the best tool for JS,
and I just see some buildings we don't need.
So, I just circle them and delete them and save them back.
Awesome.
And then I run the second pass.
I get those buildings, get period.
Also, I install Graph Corporal.
Graph Corporal is amazing routing engine.
One part, why is amazing is this one jar file.
You download it, and you run the artworks out of the box.
No installation, no Docker containers, no nothing.
This works.
And, Graph Corporal starts like showing lot of logs,
one minute passes,
and we have a JSON file.
Now, what do I do with JSON file?
I have to visualize it.
We have amazing map-libered JS project.
Which is interactive maps, the compressive lots of data.
So, I have made an HTML file.
We solve the code for it.
We have a map-libered JS, and it shows stuff.
So, we immediately have all the icons,
the charging engine generated for 15 million blocks,
district boundary, and POI with all load it.
In this case, it's childcare, like kindergarten stuff.
So, and this is like completing
that has actionable insights, that has maps,
and that can give some ideas.
As the drones are not useful.
What's more useful is buildings,
which are not accessible, which are not near,
in this case, can be in two centers.
So, people live in here,
and we know there are people living there,
because we are most buildings where people don't live.
They just cannot get there.
And, with a magic of turf JS,
the object library for the data processing,
we can merge layers.
We can, like, substract some stuff,
and we can prepare, like, big maps that show something.
And that's all actionable.
We can see where shops are missing,
where cafes are missing,
and we know what happens inside,
because we roll to the configuration file.
And that is just amazing.
I like when I understand what's going on.
Now,
yeah, I know it's just couple of minutes in times that.
So, I published the map on the Facebook, of course,
and I got my 200 likes in 90 countries.
And what I learned is that this is just the first step,
because this is all incorrect.
This is actually not actionable.
This is just the map maps are bad.
Don't use them.
Because shops are different.
Some shops are small, some shops are big,
and people need different shops for the needs.
Grouping every shop into one map doesn't work.
Like, schools are different,
because some schools in the store are Russian language,
some Australian language,
and location is just one of the factors
that people use to choose schools,
not even the most important one.
And even roads, like,
when I have to cross a road to go into shop,
I am, like, young and strong,
and I can do that.
Some people cannot.
Some people cannot climb up the stairs
to cross, like, eight lane highway.
So, even the shop is here,
they have to go a bit further,
because they just, this is impossible.
And that just with district map,
15 minutes city concept in general is a bit flawed,
but not flawed in a way that
can inspire people, like, try to show it.
Like, it's a get rise in cities and so on.
It's not right.
There are valid criticism of 15 minutes cities as well,
because it's just a part of the thing.
It's not the whole thing.
For example, when cities are already segregated,
when richly will one place and pull even another,
then when all those people get their local 15 minutes thing,
they have less incentive to live it.
They have less incentive to see each other,
and this segregation that solidifies.
And who works in those local shops and local cafes?
In a rich areas,
usually, probably people that don't live there.
They still have to come out for an entire city,
so that rich people have their 15 minutes, like local way.
Not great.
And if we are thinking about workplaces,
because this all works only if you're working remotely,
many people don't.
So we have to mix the zoning.
We have to build business centers
between residential buildings.
And my district looks like this.
People will object to turning it into something like this.
And how to get around this is what public discussions are for.
That map was just the first step.
But it doesn't mean that you shouldn't make a map.
You should.
First step is required for there to be a second, third, and other steps.
So this map has enabled me to understand that the problem is bigger.
I have downloaded more books, and I'm thinking about it more,
but the map was important, so it would be a nice exercise
if you do something like this for your district,
because you'll understand how it works.
And how to make a district better.
And so.
Thank you.
