How can I find out what altitude I am at?

If you live in the United states, you can find your elevation at the Topozone website below.

The highest altitude is West Bromwich Albions ground at 551 feet. \n\nOldham Athletics ground is only 509 feet.

The best way to figure out yardage is to stand on the 100 yard marker. Guess about a half way point where its 50 yards, and then say your inbetween the 50 and 100, your about 75, or say you inbetween the flag and the 50, about 25

Here's the official Skywatch applet from NASA\nhttp://spaceflight1.nasa.gov/realdata/sightings/\n\nJ-Pass/J-Track are no longer in active development, but accessible here, http://science.nasa.gov/realtime/Jpass/25/JPass.asp

try google earth, it's a program that you download and run but it gets updated as you move around the planet!

Downlaod Google Earth.  It has longitude and latitude adjusters so you just type it in and it will give you a location (and show it to you)

The answer to this all depends on how high your head is off the ground.\n\nThis is an excellent page where you can type in how tall you are, and it will tell you what the straight line distance to the horizon is, and the curved distance.\n\nhttp://newton.ex.ac.uk/research/qsystems/people/sque/physics/horizon/

Get an altimeter, and climb one of the sides, and notice the difference in elevations.

Cool! But if the map is on my back, how can i see the coordinates and point them out?

Guess if you note the altitude of the sun at noon each day, mid summer will be the day it climbs highest in the sky, and mid winter would be when the sun is the lowest in the sky. Spring and fall are when the sun climbs to the lattitude you're at, and then you add or subtract 23.5 degrees (the tilt of the earth) to get the altitudes of the sun at summer and winter.\n\nSo if you know you're at lattitude 45 degrees, measure the altitude of the sun each day at noon, and you'll be in mid summer when the sun is at 68.5 degrees and in mid winter when the sun is at an altitude of 21.5 degrees.

Altitude is the height above the horizon, usually measured in degrees. The horizon is at 0 degrees and the point directly overhead, called the Zenith, is 90 degrees.\n\nAzimuth is the direction along the horizon, with North usually taken as 0 degrees. So East is 90 degrees, South is 180 degrees and West is 270 degrees. Sometimes Azimuths over 180 degrees are expressed as negative numbers, so that West is -90 degrees, meaning 90 degrees from North but counting to the left instead of to the right.

altitude.....higher altitude means lower air pressure.  Liquids, water included, vaporizes at lower temp when pressure lowers.  (a glass of water will boil at room temp in a vaccumn)

you can get an approximate value by finding your location on Google Earth.\nrun the cursor over your house and it will display the elevation (in feet) at the bottom of the screen.\n\nMore precise: unless you know a surveyor, try  GPS.\nIt will give accuracies as good as .02m (under an inch)

or you can fo to ask.com and type in FAA \nand they will give you information
