This is a broad question to get me started in the right direction:
I would like to provide a location-based service so that users can tag
articles with a location (the place where the article took place), and
search (or list) articles by location.
This raises some questions:
- Presumably best practice is to allow the user not to type free-form
locations, but to help them pick a location from a list?
- Are there any frameworks that handle geographical hierarchies? For
example, an article may be tagged with a city name, and a user may want
to list all articles for a county, we'd need to know all of the cities
in each county or we'd return nothing.
The simplest thing may be to just have a flat list of places, with no
hierarchy, a list of cities and major towns for example?
Any broad advice on what's out there to provide any
geographical/location services would be much appreciated!
I'm not going to be able to help this yet, but just to add to it. What level of granularity do you want to provide? Can people search by the places within a city? How about different shops/ outlets within a city? Does it matter which branch generated the document?
