Description
Contains functions for geocoding using the OSM Nominatim APIs exposed by a Nominatim server at a given URI. By default, the GNOME Nominatim server is used, but other server details may be given when constructing a GeocodeNominatim.
Functions
geocode_nominatim_new ()
GeocodeNominatim * geocode_nominatim_new (const gchar *base_url
,const gchar *maintainer_email_address
);
Creates a new backend implementation for an online Nominatim server. See the documentation for “base-url” and “maintainer-email-address”.
Parameters
base_url |
a the base URL of the Nominatim server. |
|
maintainer_email_address |
the email address of the software maintainer. |
Since: 3.23.1
geocode_nominatim_get_gnome ()
GeocodeNominatim *
geocode_nominatim_get_gnome (void
);
Gets a reference to the default Nominatim server on nominatim.gnome.org.
This function is thread-safe.
Since: 3.23.1
Types and Values
GEOCODE_TYPE_NOMINATIM
#define GEOCODE_TYPE_NOMINATIM (geocode_nominatim_get_type ())
See GeocodeNominatim.
Since: 3.23.1
struct GeocodeNominatimClass
struct GeocodeNominatimClass { GObjectClass parent_class; gchar *(*query) (GeocodeNominatim *self, const gchar *uri, GCancellable *cancellable, GError **error); void (*query_async) (GeocodeNominatim *self, const gchar *uri, GCancellable *cancellable, GAsyncReadyCallback callback, gpointer user_data); gchar *(*query_finish) (GeocodeNominatim *self, GAsyncResult *res, GError **error); };
GeocodeNominatim allows derived classes to override its query functions,
which are called for each network request the Nominatim client makes. All
network requests are GET
s with no request body; just a URI. The default
implementation makes the requests internally, but derived classes may want
to override these queries to check the URIs for testing, for example.
Applications should not normally have to derive GeocodeNominatim; these virtual methods are mainly intended for testing.
Since: 3.23.1
GeocodeNominatim
typedef struct _GeocodeNominatim GeocodeNominatim;
All the fields in the GeocodeNominatim structure are private and should never be accessed directly.

Property Details
The “base-url”
property
“base-url” gchar *
The base URL of the Nominatim service, for example
https://nominatim.example.org
.
Flags: Read / Write / Construct Only
Default value: NULL
Since: 3.23.1
The “maintainer-email-address”
property
“maintainer-email-address” gchar *
E-mail address of the maintainer of the software making the geocoding requests to the Nominatim server. This is used to contact them in the event of a problem with their usage. See the Nominatim API.
Flags: Read / Write / Construct Only
Default value: NULL
Since: 3.23.1
The “user-agent”
property
“user-agent” gchar *
User-Agent string to send with HTTP(S) requests, or NULL
to use the
default user agent, which is derived from the geocode-glib version
and “id”, for example: geocode-glib/3.20 (MyAppId)
.
As per the Nominatim usage policy, it should be set to a string which identifies the application which is using geocode-glib, and must be a valid user agent string.
Flags: Read / Write
Default value: NULL
