• One of the most popular map tools is Open Street Map (OSM). Its main bonus is that a caring community marks everything: from large buildings to lamp posts and trash cans. Seriously about the latter, they are also marked.
• Simply put, do you need to find a government building no further than 200 meters from the railway station? We make a request to OSM and get a bunch of points on the map. Did you see a remarkable sign in the photo, and there’s a farm nearby? The problem is also solved. Only the number of variables changes.
• How is the request formed? Via Overpass Turbo . It connects via an API to OSM and executes the code you write. A request is written in QL – Querry Language, translated from Basurman – query language. This is oil oil. It also needs to be mastered, like any other programming language. This, of course, is not Python and Ruby on Rails, but it also has its own nuances.
