DESCRIPTION

36       This  package  provides  a class for accessing geocoding services which
37       implement the Nominatim interface (see References)
38

API

40       ::map::geocode::nominatim requestor ?-baseurl url? ?-callback callback?
41       ?-error error callback?
42              Creates  a  geocoding  request object requestor, which will send
43              its requests to the Nominatim server.
44
45              The result of the command is name.
46
47   OPTIONS
48       -baseurl url
49              The base URL of the Nominatim service. Default  value  is  Open‐
50              StreetMap's service at http://nominatim.openstreetmap.org/search
51              A       possible       free       alternative       is        at
52              http://open.mapquestapi.com//nominatim/v1/search
53
54       -callback cmdprefix
55              A  command prefix to be invoked when search result become avail‐
56              able.  The default setting, active when nothing was specified on
57              object  creation,  is to print the result (see below) to stdout.
58              The result of the command prefix is ignored.  Errors  thrown  by
59              the  command  prefix  are caught and cause the invokation of the
60              error callback (see option -error below), with the error message
61              as argument.
62
63              The signature of the command prefix is:
64
65              $cmdprefix result
66                     The result is a list of dictionaries, containing one item
67                     per hit.  Each dictionary will  have  the  following  en‐
68                     tries:
69
70                     place_id
71                            The place ID (FIXME: what's this?)
72
73                     licence
74                            The data licence string

81                     boundingbox
82                            The  coordinates  of the bounding box (min and max
83                            latitude, min and max longitude)
84
85                     lat    The location's latitude
86
87                     lon    The location's longitude
88
89                     display_name
90                            the location's human readable name

97
98       -error cmdprefix
99              A command prefix to be invoked when encountering  errors.  Typi‐
100              cally  these  are HTTP errors.  The default setting, active when
101              nothing was specified on object creation, is to  print  the  er‐
102              rorstring  (see below) to stderr. The result of the command pre‐
103              fix is ignored. Errors thrown by the command prefix  are  passed
104              to higher levels.
105
106              The signature of the command prefix is:
107
