OpenStreetMap and kosmosnimki.ru: mix, but do not shake

    OpenStreetMap on kosmosnimki.ruToday, approximately in the lunchtime area, kosmosnimki.ru has undergone radical ideological changes . A detailed map of the Republic of Belarus has appeared on the site. But it was not made by cartographers from commercial companies, but by ordinary people - participants of the OpenStreetMap project, and, unlike the cards of commercial suppliers, it is updated not every six months, but in real time.

    Realizing this project, we tried to take into account the accumulated baggage of experience and wishes for OpenStreetMap cards, which has been expressed more than once in various forums, and even here, on Habré.

    Of the many visible changes to the eye, in comparison with what can be seen on osm.org:
    • the color scheme is radically different and as close as possible to that already used on kosmosnimki.ru, verified by professionals;)
    • in order to see the names of settlements such as villages, now you do not need to bring the map as close as possible;
    • signed lakes and other water bodies;
    • Districts with different types of buildings (multi-storey / private) are visually distinguishable, as well as the type of building - residential, non-residential, garage ...


    A bit of technical magic, from what some considered unattainable with the current toolkit:
    • streets cut into many pieces are signed once, along the entire street, and not each segment individually;
    • multi-level interchanges, consisting of many bridges and overpasses, are drawn one above the other in the correct order.


    CrosswalkOpenStreetMap has the principle of data usage, which is described broadly on the IRC channel with the phrase “you can mix, but not shake”, and GeoMixer technology helps to fully realize it: commercial vendor cards and open cards are neatly stacked on top of each other, while their vector and raster representations are easily separable. This allows you to use OpenStreetMap data in conjunction with data from other companies without violating licensing agreements.

    And of course, what a modern web map will do without interactivity: if you move the mouse over points of interest on the map, something will pop up over them.

    I hope you will like it. Maybe you know some special places on OpenStreetMap in the ex-USSR that are already drawn better than the map that is on kosmosnimki.ru? Or maybe you will draw them right now? :)
