Title: How can I find the distance between two geographic coordinates?
Post by: Clark Kent on August 09, 2007, 09:35:34 am

So for work, I have a colleague with an interesting problem- she needs the distance, as the crow flys between two points.  I've found out how to get a lattitude longitude coordinate from google maps, but only one at a time, when I need two at once, and I also need the distance between the two points.  Does anyone have a way to do this?

This just may be helpful.  You wouldn't happen to know a good site that has maps with county borders as well, would you?

Google earth does.  Webbased maps, no; not offhand

Sounds like you need a GIS (Geographic Information System).  Google Earth will probably do what you need.

You could just use a Meractor Map and a pair of dividers!!

It worked well in the past!!
