You can use the Badger Map to do exactly this. Badger can integrate with Sugar CRM with APIs or spreadsheets so that you can see all your data from Sugar CRM on a Google Map. You can see where customers are in relation to one another, colorize and filter the customers on the map based on their attributes, and build and optimize routes and schedules to plan your day faster. You can use Badger on your computer, or it also has native apps on mobile devices.
As for me, the most convenient way would be create a report on Accounts module, where you set filter to country, and I would set display fields like this - account name, city, country, address, phone.
You can create a similar one for Leads as well.
Hope this helps!
