JavaScript

There is a database with objects, you need to display them on a map with certain connections, how would you advise doing this? geoext or somehow through qgis? we form a request, apply it to the map, load it, or initially load the entire map, and then load the necessary in the visibility area? the first work of this type, you need to understand what and how to do, thanks in advance)

Answer 1

We take a map with api (Yandex, Google, openstreetmap, etc.) study api, as a rule, there are ready-made examples that cover your tasks and feed json that we prepared based on your database.
