You can right-click a WMS service, group layer, or sublayer in the table of contents and click Properties to view the server-supported coordinate systems. If that service layer is added to a data frame with a coordinate system not supported by the WMS server, such as World Fuller, ArcMap uses the image previously received from the server and projects it on the fly.ĭepending on the coordinate system being used by the data frame, there may be some level of distortion in the display of the WMS layer-most noticeably if the layer has text.Ĭhanging to a server-supported coordinate system If the data frame is in a coordinate system that is not supported by the WMS server, ArcMap gets an image from the server in a supported coordinate system-in most cases, this will be in GCS 1984-and projects this image internally so it will display in your map.įor example, World Geodetic System (WGS) 1984 is the default coordinate system for a WMS service hosting National Aeronautics and Space Administration (NASA) world cloud free imagery. When the coordinate system is not supported by the WMS server

This information is also listed on the WMS server's Properties dialog box in ArcCatalog. Both the European Petroleum Survey Group (EPSG) number, which the WMS server uses to distinguish coordinate systems, and the name of the coordinate system are shown. Scroll through the Data Source box to see a list of the coordinate systems supported by this sublayer. The Source tab on the Layer Properties dialog box is where you will find a list of the coordinate systems.

In addition, each WMS sublayer within the WMS service can potentially support different coordinate systems. WMS servers may only support a limited set of coordinate systems, depending on how the service has been published by its author. Setting the coordinate system of a WMS service
