Questions tagged [vector-tiles]

Questions about generating or using vector geospatial data served using tiles.

Vector tiles are a way of cutting up and distributing geospatial data along pre-defined tile boundaries at various zoom levels. The most common scheme follows the same boundaries as the raster tile format used by Google Maps, OpenStreetMap and others.

Questions that are heavily about the geographic or cartographic aspects of vector tiles, or third-party software, may be better suited to https://gis.stackexchange.com
