Map integration with showing places within the particular radius

I have to do the map integration in my upcoming project.
Also, in the map I have to show the places which are nearer to that
place within the 10 miles.

Is anyone have any idea how to do this?


look at

And the geokit-rails3 gem which adds basic finders by distance. It’s not a completely functional port of the old geokit-rails because of all the changes in Rails3, but the basic distance finders work just fine.

Best Wishes,
