You can specify the location on Bing by including the "loc" parameter in the URL. The format for the "loc" parameter is "latitude,longitude" (without quotes), separated by a comma. Here's an example:
In this example, the latitude is 47.6062 and the longitude is -122.3321, which corresponds to the location of Seattle, WA in the United States.
You can replace these values with the latitude and longitude of the location you want to specify, and the Bing Maps website will display that location when the URL is accessed. Note that if you specify a location that is not recognized by Bing, it will display the nearest recognized location instead.
