I’m writing a non-fiction article. I want to determine the exact as-the-crow-flies distance (in miles, or even tenths of a mile) between two points around the NYC metro area. By my rough estimation looking at a map they are around 75 miles apart, but I want a precise number. I want to plug in the 2 locations by map coordinates and have the site tell me their distance apart. Does such an online resource exist?
If you have the longitude/latitude you can use this calculator.
Here is another calculator that will compute the distance between two cities by name, or by lat/long co-ordinates.
Just combine the sites given above with the Terra Server. You can enter and address and it will give you latitude and longitude for it.
