And after that add this HTML form:
|Web relative URL:|| |
|Bing Maps Key:|| |
|List name:|| |
|Field name:|| |
This will be your end result:
And now you have your form for adding geolocation field anywhere on your site collection. Once you have entered relative path to your web ("/" is root web) you can use Get Bing key to check if you have a BING maps key placed in that web and with Set BING key you can change or add a BING maps key to that web.
And once you enter List name and Field name you can use Create field to add a geolocation field with the name you specified to the list on the web.
Hope this helps you create you geolocation fields faster.
