The method of using specialized instruments and geometry to determine distance and elevation of specific areas is known as surveying. Surveying is used to build roads and to establish property lines of real estate.
Relief is the change in elevation in a region and measures the difference between that area's highest and lowest elevation. Elevation is the distance above or below sea level that a region is.
elevation, vertical distance from a datum plane, usually mean sea level to a point above the earth.
The method used to measure lines of longitude and latitude to determine exact location is called geodetic surveying. It involves the use of specialized instruments such as theodolites and GPS receivers to accurately measure angles and distances on the Earth's surface. These measurements are then used to calculate the precise coordinates of a particular location.
This characteristic is called altitude or elevation.
Elevation if on land Altitude if airborne above the ocean That will change depending on where you are in the world. A mapping application such as Google Earth will give you the elevation of most places on Earth with an accuracy of a few meters.
Surveying
Basic measurements in surveying include distance, elevation, and angles. Distance is typically measured using instruments like a tape measure or electronic distance meters. Elevation can be determined using a level or GPS equipment, while angles are usually measured with a theodolite or total station.
The measure of change in elevation in a certain distance is called gradient.

The distance between two points must be known to determine the average slope between the two points. You must also know the change in elevation.
distance and angle of elevation are closely related as the more closer you move, the half is the angle of elevation. for e.g. if you travel 30m and cover 15m then, the angle of elevation will be half of what you started with. this can be also proved by a live example as when you have the angle of elevation as 90 degree, then the distance can be zero....

You can determine the height of a mast by using the tangent. Measure the distance from the base, and the angle of elevation of the top of the mast as observed from that distance. The tangent is y over x, so substitute x for the distance from the base and y for the height of the mast. Solve from there. For instance, if the angle is 60 degrees and the x distance is 25 feet, then... tan (60) = y / 25 25 tan (60) = y y = 43.3
