The <input_location> element specifies an address in a format that satisfies the Oracle Spatial and Graph geocoding request XML Schema, which is described in Geocoding Request XML Schema Definition and Example. You can specify the input location using either a longitude/latitude pair or the <input_address> element. Example 13-1 in Route Request and Response Examples shows the start and end addresses specified using the <input_location> element and its child element <input_address>.
To use the <input_location> element, you must ensure that the value of the pre_geocoded_locations attribute is FALSE (the default) in the <route_request> element. You can use longitude/latitude pairs and <input_address> elements together in a request.
