We want a son from you!
In short: this post is about the unofficial rating of buildings , the 2GIS Hackathon and how we ourselves were a little stunned by what we did.

History
The idea to "evaluate" the building was born in 2GIS for a long time. Later, the idea began to walk in different departments, in every possible way to transform and overgrow with details, but it did not reach implementation in the framework of the 2GIS reference book. Therefore, it was decided to submit the project to the Hackathon.
Hackathon
So far, this is the internal 2GIS Hackathon , on which projects, processes and hypotheses are rolled on, which are difficult to integrate into current business tasks, but I really want to implement it. It takes three days: from Friday to Sunday. The company provides infrastructure, food and everything necessary. Employees at this time, of course, are disconnected from work processes. Here, a special thanks to Vitaly Kulpin.
Eight people, an open-ended idea, an atmosphere of fun and three days to make a project.
Igor Krivchun - backend
Vlad Semenov - backend
Petr Dmitrienko - frontend
Evgeny Okatiev - frontend magic
Dmitry Kuznetsov - frontend
Sergey Kolomenkin - manager
Dina Berezina - analyst
Idea - Anton Spiridonov .
In fairness, I must say that most of the design and layouts were already ready, so the main forces were thrown to “ fix bugs and deploy ”.
Project
Of course, here you can start to say pathos that Pinrate is a miracle service, thanks to which you can now:
- find the “right” place to live
- understand whether it is worth changing an apartment
- who have more to measure.
But, as already mentioned, this is not so. The project is made in an atmosphere of fun and just for fun. Of course, there were also internal tasks, but they did not really put pressure.
Filling
All data arrives from the 2GIS reference API . Maps work on the Leaflet Open Source Library and our tiles. The recently released beta API of 2GIS 2.0 cards, by the way, works the same way - 2GIS data with Leaflet under the hood.
As we consider
The site says it's magic. In fact, this is not so, and there is a formula. We take into account the distance to various infrastructure of the city and their impact on living standards.
Of course, we do not take into account the car of the parameters: neither the remoteness from the city center, nor the condition of the house, and we certainly do not know about the "funny" neighbors. We simply assumed that the better developed the infrastructure, the more likely it is that indirectly all this is at a normal level.
At the same time, we are well aware that this is "a bit" wrong and recognize that today the rating cannot be considered expert.
How to run
The project is one-time - we bet that if you already went to Pinrate, then you did it once. Played and forgot. Such a scenario we expected. Therefore, for greater coverage, they decided to go through social networks, or rather carpet bombing by sharing. For each evaluation interval, several status options were invented. From The Hole. Not black. Just a hole ”to“ King of the world, well ”(there, of course, there are fun too, but it’s better to see them yourself).
In addition, we switched to the dark side - after a few minutes on the site pop-up pops up, in which we ask to share the link.
I would also like to say how we worked with bloggers. More precisely, not only by bloggers, but by everyone who wanted to please the project (well, to get their sharing). For the buildings, which, as we expected, will be checked by “persons”, statuses from the series “who knows will understand” were invented. For example, these:

And it worked.
the effect
To be honest, we ourselves are a little bit crazy of the effect.
We were shown on TV . Information , entertainment and other sites
wrote about us . Over 7,000 tweets. Publications on Vkontakte: one , two , three and others . Several journalists contacted us. Those who were not familiar with 2GIS, first of all asked: “where do you get all the data from?” I had to talk about 2GIS itself, and about the API, and even about Flamp .
Future
We are preparing for
conclusions
There should be some kind of spiritualizing phrase, but we decided it would be more honest to say: take the 2GIS API and do as we do, do better than us (sorry) :)
Many thanks to everyone who supported and helped.
