Request the capabilities that the implementation provides (srs, formats, layers, styles) Content of the capabilities response The list of the projections that the impl provides (EPSG:XXXX) The list of the layers that the implementation provides for portraying the baseMap. To try and keep this within scope of openLS, the style of these layers is left up to the impl. The list of formats (mime-types) that the impl will encode the protrayed map with (image/gif, image/png, text/xml-svg etc) The list of available named styles Content of a presentation request Specifies the output of the map(s) that should generated The layers that should make up the baseMap. (getCapabilites provides the list the impl provides) Overlays the set of ADT's onto the basemap Context described as a bounding box Context described by a center point and scale width of the resulting map in pixels height of the resulting map in pixels mime type describing the encoding (getCapabilites provides the list that the impl provides) Background Color of the map in RGB Hex format, defaults to "#FFFFFF" (White) The opacity of the map, defaults to true if not specified Map can be returned as one of those content types The Style describing how the ADT's should be portrayed. Either a named style or a user defined style. The implementation should use a default if neither is specified The order in which the overlay's are laid on top of each other over the base map The style describing how the layer should be portrayed The layer name, getCapabilites provides a list the impl provides Portray using a named style Portray using a user defined style Clips the portrayed map with a polygon Clips the portrayed map with a circle Clips the portrayed map along a line with a corridor width Content of a presentation response
