DESCRIPTION

       This package provides a  class  for  accessing  geocoding  services  which  implement  the
       Nominatim interface (see References)

API

       ::map::geocode::nominatim  requestor  ?-baseurl  url?  ?-callback  callback? ?-error error
       callback?
              Creates a geocoding request object requestor, which will send its requests  to  the
              Nominatim server.

              The result of the command is name.

   OPTIONS
       -baseurl url
              The  base URL of the Nominatim service. Default value is OpenStreetMap's service at
              http://nominatim.openstreetmap.org/search  A  possible  free  alternative   is   at
              http://open.mapquestapi.com//nominatim/v1/search

       -callback cmdprefix
              A  command  prefix  to be invoked when search result become available.  The default
              setting, active when nothing was specified on object  creation,  is  to  print  the
              result  (see  below) to stdout. The result of the command prefix is ignored. Errors
              thrown by the command prefix are caught and  cause  the  invokation  of  the  error
              callback (see option -error below), with the error message as argument.

              The signature of the command prefix is:

              $cmdprefix result
                     The  result  is  a  list of dictionaries, containing one item per hit.  Each
                     dictionary will have the following entries:

                     place_id
                            The place ID (FIXME: what's this?)

                     licence
                            The data licence string

                     osm_type
                            The OSM type of the location

                     osm_id FIXME

                     boundingbox
                            The coordinates of the bounding box (min and max  latitude,  min  and
                            max longitude)

                     lat    The location's latitude

                     lon    The location's longitude

                     display_name
                            the location's human readable name

                     class  FIXME

                     type   FIXME

                     icon   FIXME

       -error cmdprefix
              A  command  prefix to be invoked when encountering errors. Typically these are HTTP
              errors.  The default setting, active when nothing was specified on object creation,
              is to print the errorstring (see below) to stderr. The result of the command prefix
              is ignored. Errors thrown by the command prefix are passed to higher levels.

              The signature of the command prefix is:

              $cmdprefix errorstring

   METHODS
       requestor search query
              This method returns a list of dictionaries, one item  per  hit  for  the  specified
              query.
