Elevation of Point, Line or Area Solution

STEP 0: Pre-Calculation Summary

Formula Used

Elevation of Point = (Flying Height of Airplane-(Focal Length of Lens/Photo Scale))
h₁ = (H-(f_len/P))
This formula uses 4 Variables

Variables Used

Elevation of Point - (Measured in Meter) - Elevation of point, line, or area with respect to datum.
Flying Height of Airplane - (Measured in Meter) - Flying height of airplane above datum (usually mean sea level) is defined as the average flying height above ground.
Focal Length of Lens - (Measured in Meter) - Focal Length of Lens is usually represented in millimeters (mm), is the basic description of a photographic lens.
Photo Scale - Photo scale is determined by the focal length of the camera and the flying height above the ground.

STEP 1: Convert Input(s) to Base Unit

Flying Height of Airplane: 11 Meter --> 11 Meter No Conversion Required
Focal Length of Lens: 4.2 Meter --> 4.2 Meter No Conversion Required
Photo Scale: 2.1 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h₁ = (H-(f_len/P)) --> (11-(4.2/2.1))

Evaluating ... ...

h₁ = 9

STEP 3: Convert Result to Output's Unit

9 Meter --> No Conversion Required

FINAL ANSWER

9 Meter <-- Elevation of Point

(Calculation completed in 00.004 seconds)

Focal Length of Lens given Photo Scale

Go Focal Length of Lens = (Photo Scale*(Flying Height of Airplane-Elevation of Point))

Flying Height of Airplane above Datum

Go Flying Height of Airplane = ((Focal Length of Lens/Photo Scale)+Elevation of Point)

Elevation of Point, Line or Area

Go Elevation of Point = (Flying Height of Airplane-(Focal Length of Lens/Photo Scale))

Photo Scale given Focal Length

Go Photo Scale = (Focal Length of Lens/(Flying Height of Airplane-Elevation of Point))

Elevation of Point, Line or Area Formula

Elevation of Point = (Flying Height of Airplane-(Focal Length of Lens/Photo Scale))
h₁ = (H-(f_len/P))

What is Photogrammetry?

Photogrammetry is the art, science, and technology of obtaining reliable information about physical objects and the environment through processes of recording, measuring, and interpreting photographic images and patterns of recorded radiant electromagnetic energy and other phenomena.

How does Photogrammetry Work?

Photogrammetry works by analyzing photographs of an object or area from multiple angles and using triangulation to calculate the distance and position of each point in the image. This information is then used to create a 3D model or map of the object or area.

How to Calculate Elevation of Point, Line or Area?

Elevation of Point, Line or Area calculator uses Elevation of Point = (Flying Height of Airplane-(Focal Length of Lens/Photo Scale)) to calculate the Elevation of Point, The Elevation of Point, Line or Area formula is defined as distance with respect to a datum which is calculated with the help of photo scale and focal length of the lens. Elevation of Point is denoted by h₁ symbol.

How to calculate Elevation of Point, Line or Area using this online calculator? To use this online calculator for Elevation of Point, Line or Area, enter Flying Height of Airplane (H), Focal Length of Lens (f_len) & Photo Scale (P) and hit the calculate button. Here is how the Elevation of Point, Line or Area calculation can be explained with given input values -> 9 = (11-(4.2/2.1)).

FAQ

What is Elevation of Point, Line or Area?

The Elevation of Point, Line or Area formula is defined as distance with respect to a datum which is calculated with the help of photo scale and focal length of the lens and is represented as h₁ = (H-(f_len/P)) or Elevation of Point = (Flying Height of Airplane-(Focal Length of Lens/Photo Scale)). Flying height of airplane above datum (usually mean sea level) is defined as the average flying height above ground, Focal Length of Lens is usually represented in millimeters (mm), is the basic description of a photographic lens & Photo scale is determined by the focal length of the camera and the flying height above the ground.

How to calculate Elevation of Point, Line or Area?
