Looked at their source code out of curiosity. They use Elasticsearch as a geo backend, tile server that renders PNG images server side for each map tile request. - low zoom -> server aggregated grid - high zoom -> switcher to point tiles browser just displays images, there is no work to do on client side.. I generated a visual schematic how these kind of systems work: https://vectree.io/c/server-side-geo-tile-rendering-elastics... |
