Help! I don't know my latitude and longitude!
This form, courtesy of the
geocoder.us site can probably help... US residents anyway,
since the data comes from the US census bureau.
(If your address is in the geocoder database, the coordinates are usually
accurate to within a hundred yards or so)
Enter a US address or intersection, e.g. 1600 Pennsylvania
Ave, Washington, DC.
You must include a city and state
OR a ZIP code.
If that one couldn't find the coordinates of your address, this worldwide database
probably can.
If you want to spend more time to get it
GPS accurate, load up this
google map and double-click yourself to center, zoom in 3 or 4 levels,
double click to center again, zoom, etc. Eventually you can get
close enough that (if you're in a population center) you can click
the satellite option and even make out your house.
Once there... look below the map, and you'll find the lat/long of
the center of your map.
