Converting An Address To Long/lat Numbers


Recommended Posts

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! ;)

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.
