WMS are served directly from the source you connect to your Mango account. If your source’s WMS server is experiencing issues, your tiles may not render correctly. In this instance, please check with the WMS provider.
The OpenGIS® Web Map Service Interface Standard (WMS) is an open standard for requesting and displaying geo-registered map images from distributed servers. Mango supports v1.3.0 compliant WMS that makes layers available in Web Mercator projection (SRS/CRS=EPSG:3857).
As an open standard, anyone can implement the specification. This means there is a wide variety of implementations that may or may not meet the OGC specification.
For most WMS, you will need the GetCapabilities URL of the WMS that includes the following parameters to add WMS layers to your account:
service=WMSrequest=GetCapabilitiesversion=1.3.0
https://www.gebco.net/data_and_products/gebco_web_services/2019/mapserv?request=GetCapabilities&service=wms&version=1.3.0
If you encounter issues with WMS URLS using those parameters, remove them from the URL and try to connect again.
If your WMS requires authentication, prepend username:password@ to the hostname in the URL:
https://username:password@maps.example.com/web_mercator/WMSServer?request=GetCapabilities&service=WMS&version=1.3.0
WMS must be served from a domain with a valid, complete SSL certificate. Non-SSL secured domains serving a WMS, or domains with incomplete certificate chains are not supported in Mango. Please contact the WMS provider to resolve SSL issues.
Adding a WMS layer to a map
Adding a layer from a WMS in Mango will connect that layer to your Mango data library. This layer can then be used on any number of maps. You may add any number of layers from a WMS.
WMS layers do not count towards data storage quotas.
To connect open the Upload layers window, select WMS from the dropdown box, enter the GetCapabilities request URL of the WMS into the box provided, and click Connect.
After Mango successfully connects to the service, you will be provided with a list of the layers in the WMS that are available in Web Mercator coordinate system. Select the layer you wish to link to your Mango account and click Save.
To add additional layers from the same WMS, repeat the steps above using the same GetCapabilities URL.
If the WMS server does not contain any suitable layers, you will see an error message.
Restrictions
- The service must support WMS 1.3
- The service must include layers available in Web Mercator projection (EPSG:3857). Contact the WMS provider to ask them to add SRS/CRS:3857 to the request list. In Geoserver this can be achieved in the layer's Publishing settings.
- If the WMS does not provide a legend graphic, some browsers may display a ‘broken’ image icon or a large empty image in the legend.
