One degree of latitude equals approximately 364,000 feet (69 miles), one minute equals 6,068 feet (1.15 miles), and one-second equals 101 feet. One-degree of longitude equals 288,200 feet (54.6 miles), one minute equals 4,800 feet (0.91 mile), and one second equals 80 feet.

2 dni temu · To calculate the distance between two points given longitude and latitude coordinates: Write down each point's coordinates in degrees-only format. We'll call θ and φ to their respective latitude and longitude components. d = 2R × sin⁻¹ (√ [sin² ( (θ₂ - θ₁)/2) + cosθ₁ × cosθ₂ × sin² ( (φ₂ - φ₁)/2)]).
30 gru 2020 · Given two vectors, \(\vec{a}\) and \(\vec{b}\), what is the distance between them? On a plane, we can break up each vector into its components and use the Pythagorean theorem: \[ \text{distance} = \sqrt{(a_x-b_x)^2 + (a_y - b_y)^2}\]
Displacement has to be the shortest path between the two points. If you go around in a circle back to where you started, distance is the circumference of the circle. Displacement is zero.
d = distance to the object. Example: A certain telescope on Earth can see details as small as 2 arcsec. What is the greatest distance you could see details as small the the height of a typical person (1.6 m)? d = 206,265 D / θ. d = 206,265 × 1.6 m / 2. d = 165,012 m = 165.012 km.
18 cze 2022 · In the case of Earth observations, the planet-Sun distance ab = 1 A.U. so d = 1/p. From Earth you simply flip the parallax angle over to get the distance! (Parallax of 1/2 arc seconds means a distance of 2 parsecs, parallax of 1/10 arc seconds means a distance of 10 parsecs, etc.)
14 mar 2013 · I am working on a tool to find the distance between two points whose latitude and longitude are given. Its ok when the latitude and longitude is given in Signed Degree Format.
