Assign an app that stores geocode data for photos. I want to be able to return albums of photos within a city or within a country.
Currently uses the location string for the database ( location_name = "London, UK"), it is very simple calculation compared to the query actively through map geometry But there is the issue of accuracy. In addition, due to alternative names or localization, there is no reason to record ("London, UK" will not match "London, United Kingdom")
Radius Search is an option with great circle distance, But for the geographical areas that are weird size (for example Tennessee or Texas), which also presents the issues of accuracy.
So, what is the best way to spot the location in the database?
