Higher Ground "Half of New Orleans is at or above sea level" .
A yearlong topographic and demographic study of New Orleans arrives this month like the latest installment of the television series "MythBusters" -- and may forever change the notion of the Big Easy as a below-sea-level city.
"Contrary to popular perceptions, half of New Orleans is at or above sea level, " according to the study by Tulane and Xavier universities' Center for Bioenvironmental Research.
(SNIP) "Innumerable media reports following Hurricane Katrina described the topography of New Orleans as unconditionally below sea level, " the study notes.
"This oversimplification is inaccurate by half, and its frequent repetition does a great disservice to the city." (BIG SNIP) "LIDAR elevation data show that 51 percent of the terrestrial surface of the contiguous urbanized portions of Orleans, Jefferson, and St.
Bernard parishes lie at or above sea level (with the highest neighborhoods at 10-12 feet above mean sea level) , while 49 percent lies below sea level, in places to equivalent depths.".

From Sea to Prairie--18--Maps
Where would you begin? When Coronado and his men began their search for gold in 1541, they had to depend on Indian guides and natural landmarks such as rivers and hills to keep them on course.
Sea level is the average level of all the oceans in the world.
This is what North America looked like at one point during the Cretaceous Period about 100 million years ago when a sea covered part of Kansas.
Can you find Kansas? Click on the map to see! The distance above sea level at a particular point is called the elevation.
If you were standing on a sea shore, you would be approximately at sea level.
The elevation of the top of a hill rising 10 feet from the flat beach would be 10 feet above sea level.
Even though some areas of land can be below sea level, all land in Kansas is above sea level ranging from about 700 feet in the southeast to over 4, 000 feet in the west.
Next time you ramble through the hills and plains of Kansas in search of mosasaurs, camels, or large woolly mammoths, take a map.

Integers
Problem: The highest elevation in North America is Mt.
McKinley, which is 20, 320 feet above sea level.
The lowest elevation is Death Valley, which is 282 feet below sea level.
McKinley to sea level is 20, 320 feet and the distance from sea level to the bottom of Death Valley is 282 feet.
The problem above uses the notion of opposites: Above sea level is the opposite of below sea level.
positive, negative We could solve the problem above using integers.
In the number line above, + 3 and - 3 are labeled as opposites.
Example 1: Write an integer to represent each situation: 10 degrees above zero + 10 a loss of 16 dollars - 16 a gain of 5 points + 5 8 steps backward - 8 Example 2: Name the opposite of each integer.
