WMS / WMTS

Add WMS or WMTS imagery to Felt as a map layer or shared source. Check supported versions and required URL parameters.

A Web Map Service (WMS) or Web Map Tile Service (WMTS) is an Open Geospatial Consortium (OGC) standard for serving map images, such as NOAA or NASA GIBS imagery. Felt adds a service's layers to maps as raster layers and requests their images from the service as the map loads, so WMS and WMTS layers don't count toward your workspace's processing limit. You can add a service to one map from a URL, or connect it as a source that everyone with access can use on any map.

Add a WMS or WMTS layer to a map

Add a WMS or WMTS layer from a URL that meets the URL requirements.

1. In the center of the toolbar at the top of the map, click Upload Anything > From URL.

2. Paste the service's URL and click Add to map. The layer appears in the legend.

See Add data from URLs.

Connect a WMS or WMTS source

Connecting a WMS or WMTS source needs Edit access to the workspace. Follow the steps in Add a source, select WMS / WMTS, and in Connection, enter the service's URL. If the server accepts requests only from known addresses, allow Felt's IP addresses. Felt lists each of the service's layers in Data sources. To show one on a map, select it and click Create layer.

URL requirements

Felt reads the service's capabilities from its URL, so the URL must point to the service itself, not to one tile or image.

• The URL must contain wms or wmts, regardless of capitalization, such as https://example.com/geoserver/wms.

• Felt requests the service over HTTPS, even from an http:// URL. A server that supports only HTTP doesn't work.

• Felt supports WMS 1.3.0 and 1.1.1, and WMTS 1.0.0. To force a version, add a version parameter.

• To add only some layers, list them in the layers parameter (WMS) or the layer parameter (WMTS). Otherwise, Felt adds every layer in the service.

• Felt keeps other parameters, such as an API key or a style.

Felt requests WMS images in Web Mercator (EPSG:3857), so the server must support that projection. A WMTS layer in another projection is reprojected.
