GetPortrayal.xsd 2005-07-05 This XML Schema encodes the FPS GetPortrayal operation request message. Copyright (c) Open Geospatial Consortium (2005) Request to a FPS to perform the GetPortrayal operation. This operation allows FPS clients to request and receive back styled digital feature data in a portrayed map-like image. The styles applied are identified or specified by the client, and are applied to digital feature data identified by the client. In this XML encoding, no "request" parameter is included, since the element name specifies the specific operation. Optional reference to the data format to be used for the response to this operation request. This element shall be included when multiple output formats are available, and the client desires a format other than the specified default, if any. BoundingBox surrounding desired subset of features to be portrayed, in desired CRS. The supported CRS values are specified in the service metadata (Capabilities). In this application of ows:BoundingBox, the “crs” for that BoundingBox shall always be referenced and shall always have two axes (i.e., be 2D or two-dimensional). The CRS referenced in the BoundingBox shall be the desired CRS for this feature portrayal. Since the FPS does not perform coordinate conversion, this CRS identifier shall be passed on to the identified WFS to retrieve feature data in this CRS. Reference to Symbology Encoding document. Symbology Encoding document contents. NOTE: The type of this element needs to be specified (TBD). Specifies desired portrayal output data. Width of desired output, in pixels. Height of desired output, in pixels. Background transparency desired. Include when non-transparent background desired. Background colour desired. Include when background colour desired. Reference to format in which operation exceptions should be returned. Include when default XML not desired. Identifier of format in which operation exceptions should be returned. Use normal XML formal (text/xml). Return exception message in portrayal image. Return blank portrayal image. Specifies chained OWS from which to get data, plus how to get desired data. Identifier of service type from which to request data. The string value is the OWS type abbreviation, such as "WFS" or "WCS". Reference to the specific OWS server from which to request data. Value is URL for HTTP GET transfer of the GetCapabilities operation request. Reference to the feature TypeName to be used to retrieve the desired features from a WFS. Filter used to specify which features to retrieve from a WFS, to be used in the request. Include when needed.
