FINDING YOUR LATITUDE/LONGITUDE/
ELEVATION
U.S.Locations: The easiest source is the Internet site:
www.topozone.com. Choose Get a Map and enter your
town or county in the Place Name Search. It will show eleva-
tion and Lat/Long as a decimal. Double click on the town
name and a map will appear. At the bottom of the map, select
D/M/S. Then look above the map for Lat/Long in degrees/
minutes.
If you know your Lat/Long as a decimal, you can convert to
minutes by multiplying the decimal numbers by 60. EXAM-
PLE: For Lat 35.407 , multiply .407 x 60 = 24.42. Lat = 35
24’(Round to nearest whole number.)
If you have a GPS, the Lat/Long should come up when you
first turn on the unit. Many GPS units also provide eleva-
tion.
If you do not use the Internet and do not own a GPS, call your
local airport, which can provide the Lat/Long/Elevation of
the airport. Some airports can give you information on sur-
rounding areas.
If there is no convenient airport, call the U.S. Geological Sur-
vey at 888 275 8747 to order the USGS Index to Topo Maps
for any state. These are free and are shipped to you free by US
mail. You may also call the same 888 number, press 6 for the
USGS Library. The librarian can look up your location.
Remember that most local libraries have Internet access, or
you may ask the Reference Librarian to check
www.topozone.com, or other sources, for the Lat/Long/Eleva-
tion information you need.
Canada: Use www.NRCAN-RNCAN.gc.ca. Click on Cen-
tre for Topographic Information, then select MAPS 101. Go
to the bottom and select Search on Index; select NTS Index
Maps, then click on Geographical Name Query. Type in your
location.
International Locations: You may use www.mapquest.com
and select World Atlas or locate information for your indi-
vidual country.
