How can we measure the hight of hill?

Answer 1

Topographical maps have contour lines which are measured using mean sea level as "zero elevation". All other elevations are compared to sea level. When you look at a topographical map, the contour interval (meaning the vertical distance represented between each contour line) can be found in the margin of the map or in the map's legend. Additionally, you'll find that a hill is generally named for its elevation. For example, "Hill 781" is seven hundred and eighty-one meters above sea level.

Answer 2

topography, first you need to know, your height
in relation to your sealevel meassurement.
as a point of indication.
most countries having there own sea level
meassurement. (your standard point)
you need to know how high you are standing
at the point of your device, in relation to the sealevel point
they are using a instrument,not unlike a sextant
with a small telescope.
now wat you are going to do is first take a
meassurement, of a strait line of 90 decrees
than you meassure the top of the hill.
the difference in decrees will be your info
this angle can be calculated, and than you know the height of the hill.
