How do they measure elevation?

Answer by  Cecilia (2828)

In High School Math we used algebra and trigonometry to determind the elevation of an object. The simplest method compares the relationship between a known object and the observed object.

They use the engineer sea levels to measure the elevation that is used. You can take the sea level and using that you measure elevation.

Elevation is measured in terms of feet above sea level. With modern technology they can use things such as barometric pressure or lasers to measure how high a mountain is.

what one must do is to use a gps/ gis survey piece of equipment. this involves triangulating the exact location and elevation of the given point via atleast 3 satalites.

Answer by  Stan (75)

Elevation is usually measured between the point you want to measure versus a universal standard, typically the mean elevation of the ocean (taking high and low tide into consideration) as water elevation is the same throughout the world. Other universal standards could include a fixed point in space (GPS Satellites).

There are a ton of different ways for different purposes and for how accurate it needs to be. A pressure altimeter found in most aircraft measures the air pressure. The closer to sea level you get, the stronger the pressure becomes.

They measure elevation in feet. They start the measurements at sea level, and go up to the point of actual land.
