Correct Coordinates

Thanks for that. Very useful

This does indeed work and can be quite handy, but the coordinates often need adjustment if you are trying to navigate to them.

For example, when latlong gives you coordinates for a business in a mall, your GPS often can't give you exact directions to it unless it knows where the mall entrance is.

I usually check the location with Google Earth and change the coordinates to the mall entrance if necessary.

I’m not sure of the accuracy. I selected an address of an establishment in southeast Pennsylvania and acquired latitude and longitude using the suggested method and also two other methods, MapQuest and Google Maps. There were differences that were significant; as much as 0.02 degree latitude. 1.0 degree of latitude is about one nautical mile, about 6080 feet so 0.02 error amounts to about 121 feet. Which of the three is the most accurate?

One minute of latitude is about one nautical mile, so the discrepancy is 60 times larger than you quoted. Almost 7300 feet.

You are correct! I went back and rechecked the three sets of lat/long and the maximum error remains at 0.02 degree.

Thanks for letting me know! I would always manually use Google Maps or OSM but this is way better.

I gave it a quick try. It looks like a decent program.
