22.4 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 -m or --max=.

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 -u, --url, -o or --osm``), Bing Maps (-bor–bing), or Google Maps (-gor–google`).

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:

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.
