What is WMTS?

WMTS (Web Map Tile Service) is an OGC standard for fetching pre-rendered map tiles (PNG/JPEG) at fixed zoom levels. The server pre-cuts maps into tiles; the client requests only tiles for the current viewport — faster than WMS for pan/zoom in web viewers.

Base maps, orthophotos, and BRT are often offered as WMTS or tile equivalents. GeoServer and PDOK-like services can publish WMTS alongside WMS. GeoApps and web GIS clients use WMTS for smooth backgrounds.

WMTS is not WFS (no features/attributes) and not dynamic WMS render per request at every scale — tiles are static until the cache refreshes. For current thematic layers WMS or vector (WFS) remains needed.

WMTS belongs to OGC and web GIS; it is the performance layer behind fast map apps, alongside ECW/GeoTIFF archives often converted to tiles first.
