WMTS (Web Map Tile Service)

WMTS is an OGC standard for serving pre-tiled raster maps. It is faster than WMS because tiles are cached on the server. Use it for high-resolution basemaps, aerial imagery, or thematic maps from national mapping agencies.

Connecting a WMTS

1. Open the Layers panel and click +.
2. Select Connect stream and choose WMTS.
3. Enter the service URL.

6. Click Add.

What is configured automatically

When you use Fetch layers, AugmentCity reads:

• Layer identifier, title, and abstract
• Available styles — the default style is selected automatically
• Tile matrix set links — the first available set is selected
• Image format — the first supported format is used

You can change the style or tile matrix set using the dropdowns before adding the layer.

Field	Example	Notes
