The 3 screen shots are from the “Satellite Dish Look Angle Heading Calculator” at www.sadoun.com/Sat/Installation/Satellite-Heading-Calculator.htm. I like it for finding distance from point A to point B. The big screen shot in the background is Google. Right click anywhere to get Lat - Lon.

You can go to http://skyvector.com/ and select a sectional of any area in the US then right click anywhere on the map to get the Lat-Lon. You can also click "plan" then scroll to the next location, right click and click "plan" and you will get the distance and heading.

This is the best site I know of to get good lat-lon address. http://www.getlatlon.com/
