How to mark a lot of addresses on one map?

Question

Google

I have 51 thousand addresses (country, city, street, house number), and they all need to be marked on one map (Google or Yandex).
What is the best way to do this?

Answer 1

1. First, convert addresses to coordinates with a script:
api.yandex.ru/maps/doc/geocoder/desc/examples/geoc...
2. Display with a simple code:

var myMap;
ymaps.ready(init);

function init () {
    myMap = new ymaps.Map('map', {
        center:[55.76, 37.64],
        zoom:10
    });
  
  // Эта строка запрещает передвигать карту
  myMap.behaviors.disable(['drag', 'rightMouseButtonMagnifier']);

    var coords = [
    [55.76, 37.64],		// Москва
    [56.31, 43.98],		// Нижний Новгород
    [54.28, 48.24],		// Ульяновск
    [52.30, 104.28],		// Иркутск
    [62.02, 129.73],		// Якутск
    [64.72, 177.49],		// Анадырь
  ],
  
    myCollection = new ymaps.GeoObjectCollection({}, {
       iconImageHref: 'http://ваша_иконка',
     iconImageSize: [16, 16],
       iconImageOffset: [-8, -8]
    });

  for (var i = 0; i < coords.length; i++) {
   		myCollection.add(new ymaps.Placemark(coords[i]));
  }

  myMap.geoObjects.add(myCollection);
  myMap.setBounds(myMap.geoObjects.getBounds());
    };

You can use geocoding directly, but Yandex itself does not recommend doing this - for a long time. Well and a clustering at will to include.
