![]() Viewing a WMS service from a cached-on-demand map service will create tiles in the cache if the user navigates to uncached areas. WMS services can only use map service caches image service caches are not supported. If you have only a few layers and uncomplicated symbology, you may get better performance without a cache. You'll see the most benefit using a cache if your WMS service has many layers or sophisticated symbology that would otherwise take a long time to draw dynamically. The cached tiles are resampled to fit the scale requested by the client, which can take some processing time and reduce the image quality. The map service cache is only used when requesting the original layer order and layer visibility of the service. WMS services take advantage of a map service cache if one is available. You may be able to reduce the startup time by removing or consolidating layers in the service. The number of layers in the map directly affects the amount of time it takes to initially create the WMS service or start it after it has been stopped. When you publish your map or image service, make sure you enable the WMS capability by checking the WMS check box on the Configuration tab. To publish an image service, you need to have either a raster dataset, a mosaic dataset, or a layer file referencing a raster dataset or mosaic dataset. Publish an image service with the WMS capability enabled.To publish a map service, you first need to create a map document. Publish a map service with the WMS capability enabled.There are two ways you can publish a WMS service: ![]() You can learn more about WMS services at the Open Geospatial Consortium website. To expose data as raster layers, publish a WCS service. To expose your data as vector features through OGC specifications, publish a WFS service instead. The map images returned by a WMS service do not contain actual data, although attribute requests can be made through the GetFeatureInfo operation. Both the GetStyles and GetLegendGraphic operations are only applicable in a Styled Layer Descriptor (SLD) WMS service. It is not necessary for a WMS service to support all the operations, but it must support at least the GetCapabilities and GetMap operations to be a basic WMS and support the optional GetFeatureInfo operation to be a Queryable WMS. Requesting legend symbols (GetLegendGraphic).Requesting user-defined styles (GetStyles). ![]() Requesting information about features in the map (GetFeatureInfo ). ![]()
