How to know if a

  • WMS
  • ArcGIS mapservice

are tiled or not? Which test can answers to the question?

  • 1
    JavaScript Client libraries that allow you to specify tiled/or not for a WMS service, aren't relying on the WMS service being tiled or not (because WMS don't support tiling), rather it affects the type of request made to the server, either a single image to cover the map canvas, or several small ones

  • However, for example OpenLayers in the tiled WMS mode adds &tiled=true and that allows caching on the client side, and WMS-C capable server to utilize its own cache openlayers.org/en/latest/examples/wms-tiled.html.

The WMS standard does not support tiling, but the OSGeo organization defined a long time ago a well defined profile to use WMS as tiled https://wiki.osgeo.org/wiki/WMS_Tile_Caching.

At least GeoWebCache https://docs.geoserver.org/stable/en/user/geowebcache/using.html, MapProxy https://mapproxy.org/docs/nightly/services.html#wms-c, and MapCache https://mapserver.org/mapcache/services.html support WMS-C. All these servers use the same vendor parameter &tiled=true. User can check if WMS server supports WMS-C by checking the capabilities with a request like


At least today this WMS-C server is open and online


WMS-C servers add the information about the supported TileSets into GetCapabilities

<BoundingBox SRS="EPSG:4326" minx="-180.000000" miny="-90.000000" maxx="180.000000" maxy="90.000000"/>

ESRI has never supported WMS-C https://community.esri.com/t5/open-and-interoperable-questions/wms-c/td-p/8878. Generally speaking WMS-C was an early trial to add support for tiling into OGC services and it became mostly needless when OGC published the WMTS standard.

  • GetCapabilities without the tiled parameter, reveals the tile capability if one exists

  • Some servers reveal, some don't. GeoWebCache does not mention tile capability when the capabilities are read with localhost:8080/geoserver/gwc/service/…
