I need a google maps API script done for my next project. Basically I have a database of all the zip codes in the united states with latitudes and longitudes for each.
1. Google Maps is loaded
2. The user can highlight an area on the map
3. The script then uses the database of latitudes and longitudes of zip codes to figure out which are within the highlighted area.
4. The script shows all the zip codes that are within the area
The reason for this script is that I will have a website where I will list flower shops that deliver flowers, for each of these shops I need to figure out exactly to which zip codes they deliver to by allowing the user to highlight the delivery area.
