BufferBufferCreate a buffer around a GML geometry. Accepts a GML geometry and provides a GML geometry output for the buffered feature.InputGeometryInput Geometry to be bufferedThe Geometry to be buffered.text/XMLUTF-8http://schemas.opengis.net/gml/3.0.0/base/gml.xsd1BufferDistanceBuffer DistanceThe width of the buffer must be beween 1 and 101.Integer11010EndCapStyleEnd Cap StyleThe Style of the generated end caps of the buffer. Possible values are 1 (round caps), 2 (end caps are truncated flat at the line ends), and 3 (End caps are squared off at the buffer distance beyond the line ends).Integer130ApproximationQuantizationApproximation QuantizationThe number of quadrant segments for different curve approximation levels of end caps. An integer between 8 (dafault) and 20.Integer8200Buffered GeometryBuffered GeometryGML stream describing the buffered Geometry.
