I looked on wikipedia and it says....OK SWEETIE EVERY THOUGHT BOUT WIKIPEDIA meanie
The city of Brownsville is located at the lowest point in Texas, with an elevation of approximately 18 feet above sea level.
The lowest point of elevation in Pittsburgh is located at the confluence of the Allegheny and Ohio Rivers, specifically near the point where the rivers meet at Point State Park. This area is approximately 710 feet (216 meters) above sea level, making it the lowest natural elevation in the city. The park is a significant historical site and offers scenic views of the rivers and the city skyline.
The lowest point of elevation in Wyoming is 3,101 feet above sea level at the Belle Fourche River where Wyoming borders South Dakota.
New Orleans -8 ft below sea level
Monaco Elevation: 140m
The city with the lowest elevation in North Dakota is Tolley, which is located in Renville County. It has an elevation of approximately 1,480 feet above sea level.
Surrey, BC, Canada extends all the way to the ocean. It's lowest elevation is therefore sea level.
well elevation is the distance in a particular location between the surface and where the surface of the sea would be at a 90 degree angle measurement (if up to sea level then it's a negative elevation, down to sea level it's a positive elevation). So the elevation of a city would either be the lowest or highest natural (not manmade like a building) point in the city or the average elevation of the city(i'm pretty sure it's this) or the average of the lowest and highest point in the city.
The lowest point of the Mississippi River is in the extreme south of its delta as the river branches and empties into the Gulf of Mexico. The probable lowest point of the State of Mississippi is in the city of New Orleans which mostly lies below sea level.
The lowest point in London is the River Thames at Greenwich, which is approximately 0 meters (sea level). This area is significant as it represents the reference point for measuring elevation across the city. The Thames flows through London and has various tidal influences that can affect its level.
The lowest point is the river Rhine in the centre of the city. This is about 250 metres above sea level. The highest point, Bruderholz, is about 400 metres above sea level.
