# Converting An Address To Long/lat Numbers

## Recommended Posts

I have multiple websites that convert numeric waypoints/coordinates to a regular address....but does anyone have a website so I can do the opposite: get a regular address converted to waypoint numbers?

Thanks,

Thank you for the information. I have to admit my ignorance here... I converted it according to the geocode site, but I didn't recognize the format. I tried to use what it gave me as "decimal degrees"....converted my GPSr to read decimal degrees, plugged it in, and then converted my GPSr back to Deg/min/sec. When I plugged that into the Mapquest long/lat to check the address for accuracy, it told me it was an invalid number.

The Deg:Min:Sec format on the geocode.com site is written differently than I've ever seen before. For example, instead of hdddºmm.sss, it is written like this:

42:18:21.118N

71:31:55.225W

The decimal degrees was written with an extra digit that threw my GPSr, and that might have had something to do with it??

42.305866

-071.532007

Any idea on how to get this into my GPSr?

Thanks.

This one is in dd:mm:ss.sss format. For the more familiar dd:mm.mmm format, divide the "ss.sss" part by 60 and use it for the ".mmm" part.

21.118 / 60 = 0.351967

55.225 / 60 = 0.920417

rounded coords:

N 42 18.352

W 071 31.920

And this one is just dd.dddddd. For dd:mm.mmm, multiply the ".dddddd" part by 60 and use it for the mm.mmm part:

0.305866 * 60 = 18.35195

0.532007 * 60 = 31.92042

rounded coords:

N 42 18.352

W 071 31.920

Hey, they're the same!

Awesome! Thank you! I'm going to save your post reply so I can do that again in the future. Many thanks for the lesson! We'll be using it in an upcoming puzzle cache.

anyone know of something similar to this for any place other than the US?

I think Maporama.com will work outside the US

Geocode.com is pretty slick, but I have found it to be off by quite a few hundred feet on occasion. I haven't found a more accurate site yet.

Thanks Stunod.

I've also found this one that may come in handy around here.

Free geocoding service for 18 countries. Don't bet your life on the coordinates for any address in any country being absolutely correct. Addresses aren't surveyed, they're just calculated from assumptions of lot size, odd numbers on the left, etc. Some can be very wrong.

I'm not sure how a double post happened. One click, two posts. Oh, well.

I list my favorites in my FAQ

I had the same question for England. I put the question on the UK board and the answer I got was to try Streetmap.co.uk

I plugged in addresses and got the reply in the standard Long/Lat, but only to two decimals. That should be good enough to find the big castle down the street.

Check out Terraserver.com. They will give the lat/long of US addresses but only general city lat/long for other countries.
