20.4 bing geocode
20210525 The geocode command takes a supplied address and produces specific location details.
$ ml geocode bing [options] <address> -b --bing Generate Bing Maps URL. -g --google Generate Google Maps URL. -m <int> --max=<int> Maximum number of matches. -o --osm Generate Open Street Map URL. -u --url Generate Open Street Map URL.
The output, separated by commas, consists of the latitude:longitude (north/south : east/west) location, a bounding box for the region (south latitude : west longitude : north latitude : east longitude), the confidence that the identified location is a match, a match code (good, ambiguous, uphierarchy), the entity type. The remaining output is the identified address (which will generally has commas within it). In summary, that is:
If the location is ambiguous then several rows will be returned, one for each possible location.
You can control the maximum number of matches (1-20) with the default
being 5, through
Instead of providing the output described above you can request a URL
(universal resource locator) be returned. The URL is a link to a map
using either Open Street Map (preferred and default for
--osm``), Bing Maps (-b
), or Google Maps (-g
The following example splits the single line of output across several lines here for presentation. We geocode a specific locality:
$ ml geocode bing --max=1 anzac parade
This identifies it as:
-33.955379486083984:151.2429656982422, -34.12508010864258:151.07327270507812:-33.78567886352539:151.41265869140625, High,Ambiguous,PopulatedPlace, Anzac Parade, NSW, Australia
The URL generation defaults to producing a URL link to Open Street Maps:
$ ml geocode bing --url anzac parade
There are actually three matches for this address.

You can copy and paste the URL into a browser. But suppose you want to display the second match above directly into the browser:
$ brave-browser `ml geocode --url bing anzac parade | sed '2q;d'`
The sed command (the stream editor) operates on the second line sent through the pipeline, printing it but deleting the other lines, and quits. Change 2 to 3 in the sed, for example, to get the third match.
