A simple WordPress plugin to add location information to posts.
It uses Google's Geocoding API, taking in a street address and churning longitude, latitude, country and zip code.
If, for instance, you've already have longitude and latitude (from, say, a WordPress mobile app), then DCoGeoMakeHappyBaby will add more complete geo information.
The plugin will know if you have already put in longitude and latitude into your custom meta keys and reverse geocode to grab street address, country and zip code.
I cannot answer that. I'm bashful.
