## algorithm - Calculate distance between two latitude-longitude points

Greater Circle Distance Algorithms are used to calculate the distance between two points which assumes earth as a spherical object. Haversine Algorithm is used to calculate this distance. Most of us are more accustomed to seeing latitude and longitude simply as lines on a gridded map, but few consider their actual potential. In the real world, latitude and longitude play an important role in several fields and calculations, but one of their most common uses is measuring distances between.. Longitude is defined as imaginary lines called meridians that run from the north to the south pole. There are a total of 360 meridians. Most interactive map applications will allow you to input GPS coordinates of latitude and longitude and tell you the distance between the two points "> const x = (λ2-λ1) * Math.cos((φ1+φ2)/2); const y = (φ2-φ1); const d = Math.sqrt(x*x + y*y) * R; This uses just one trig and one sqrt function – as against half-a-dozen trig func­tions for cos law, and 7 trigs + 2 sqrts for haversine. Accuracy is somewhat complex: along meridians there are no errors, otherwise they depend on distance, bearing, and latitude, but are small enough for many purposes* (and often trivial compared with the spherical approxima­tion itself).As described above, lines of longitude converge between their greatest separation at the equator to their meeting at points at each pole. This means that the distance between longitude lines grows shorter as one moves from the equator toward one of the poles.

The Spherical distance between OKC and Norman is 28 Kms calculated using MYSQL st_distance_sphere formula. The st_distance_sphere gives the distance in metres and that’s the reason I have divided it by 1000 in the Select Query to get the result in KM.You can, however, use basic trigonometry to find out how far apart lines of longitude are if you know your latitude. Imagine the Earth from the side, with you standing on this apparent circle at 40° north latitude. If you draw a line from the center of the circle to yourself, it creates an angle of 40° with a horizontal line drawn through equator and a vertical line drawn between where you stand and this horizontal line. This forms a right triangle, with the hypotenuse being the Earth's radius of about 4,000 miles.

Importantly, though, thanks to the whims of trigonometry, this does not happen at a uniform rate. This means that, for example, lines of longitude are not simply half as far apart at 45 latitude (which would be about 34.7 miles) as they are at the equator. decimal. Latitude.

### Latitude/Longitude Distance Calculato

• To create a full grid system allowing for the full specification of north-south and east-west position on the globe, a line of longitude needed to be chosen to serve as 0° east and west longitude. That invisible line, called the prime meridian, passes by historical convention through Greenwich, England. (Lines of longitude are also called meridians; lines of latitude are sometimes referred to as parallels.)

• All these formulas are for calculations on the basis of a spherical earth (ignoring ellipsoidal effects) – which is accurate enough* for most purposes… [In fact, the earth is very slightly ellipsoidal; using a spherical model gives errors typically up to 0.3%1 – see notes for further details].

• Key to calculations of rhumb lines is the inverse Gudermannian func­tion¹, which gives the height on a Mercator projec­tion map of a given latitude: ln(tanφ + secφ) or ln( tan(π/4+φ/2) ). This of course tends to infinity at the poles (in keeping with the Mercator projec­tion). For obsessives, there is even an ellipsoidal version, the ‘isometric latitude’: ψ = ln( tan(π/4+φ/2) / [ (1−e⋅sinφ) / (1+e⋅sinφ) ]e/2), or its better-conditioned equivalent ψ = atanh(sinφ) − e⋅atanh(e⋅sinφ).

Convert between Polar and Cartesian Coordinates - Cartesian and Polar coordinate converting. Latitude and Longitude Converter - Convert.. If the straight lines are parallel, the distance between \$\$r\$\$ and \$\$s\$\$ is the distance from a point of any of both straight lines to any other. As the straight lines need to have parallel director vectors, we can suppose that they do have the same, which is why \$\$A = A'\$\$ and \$\$B = B'\$\$ Calculating the distance between latitude lines is easy because this distance never varies. If you treat the Earth as a sphere with a circumference of 25,000 miles, then one degree of latitude is 25,000/360 = 69.44 miles. A minute is thus 69.44/60 = 1.157 miles, and a second is 1.15/60 = 0.0193 miles, or about 101 feet. The shortest distance between two points is a straight line, but how long is that line?

• An intermediate point at any fraction along the great circle path between two points can also be calculated.1
• You can now figure out the horizontal distance between a vertical line through the Earth's center and yourself. This is the same distance as the length horizontal leg of the right triangle, which you can call x. Since the cosine of a right triangle is the adjacent leg divided by the hypotenuse, in this case, you have cos L = x/R. where L = latitude = 40° and R = 4,000. Since the cosine of 40° is 0.766, x = (4,000)(0.766) = 3,064 miles.
• Because the Earth rotates on an axis passing through points chosen to represent absolute north and absolute south (i.e., the poles), an observer watching you from a fixed point in space would see you whirling around laterally and thus changing your horizontal position from her view, but would not see your vertical position change. This makes the equator an automatic reference point.
• ed by converting the latitude/longitude values to values on an X/Y coordinate plane
• e north, and knowing the annual rotation of the constellations was enormously important on the open sea, which offered no other reference points.
• Historical aside: The height of tech­nology for navigator’s calculations used to be log tables. As there is no (real) log of a negative number, the ‘versine’ enabled them to keep trig func­tions in positive numbers. Also, the sin²(θ/2) form of the haversine avoided addition (which en­tailed an anti-log lookup, the addi­tion, and a log lookup). Printed tables for the haver­sine/in­verse-haver­sine (and its log­arithm, to aid multip­lica­tions) saved navi­gators from squaring sines, com­puting square roots, etc – arduous and error-prone activ­ities.

## Preprocessing: Calculate the Distance Between Longitude and

You can check the distance between literally any two locations on planet Earth! Are you planning a trip cross-country? Are you just curious about how far it really is from London to San Francisco? The exact distance, in miles and kilometers, between any city, town, airport, zipcode or specific address.. The horizontal distance between the points is 4 and the vertical distance is 3. Let's introduce one more point (-2, -1). With this small addition we get a This is of course always the case: the straight line segment whose length is taken to be the distance between its endpoints always serves as a.. The simpiler formulas assume that the Earth is a sphere, and are in error by up to 0.3%. The error is 0.0647 miles (341.6 feet) for your location.3959 # radius of the great circle in miles...some algorithms use 3956 6371 # radius in kilometers...some algorithms use 6367 3959 * 5280 # radius in feet 6371 * 1000 # radius in meters

Calculating the distance between latitude lines is easy because this distance never varies. If you treat the Earth as a sphere with a circumference of This means that, for example, lines of longitude are not simply half as far apart at 45 latitude (which would be about 34.7 miles) as they are at the equator Latitude and longitude, coordinate system by means of which the position or location of any place on Earth's surface can be determined and described. Latitude is a measurement of location north or south of the Equator. Longitude is a similar measurement east or west of the Greenwich meridian Distance Calculator » Need the distances between two places?

How do I figure the milage (east-west) of each degree and/or minute? I'm supposing the longitude distance stays the same but latitude changes. I seem to remember that the distance around the earth is the cosine(?) of the latitude or something like that so maybe that's the key?

The along-track distance, from the start point to the closest point on the path to the third point, is Copy link Quote reply RosiersRobin commented Mar 13, 2017 Can this be modded to work with ALOT of longtitudes and latitudes? From Quito, trace a longitude line to the north pole; then make a 90-degree turn to the right and head straight back down. Now draw a line along the globe's surface starting at Quito and going toward Libreville. You probably went eastward, passing over Brazil and the Atlantic Ocean

## Formula to Find Bearing or Heading angle between two points

More commonly, latitude and longitude are expressed as positive (north and east) or negative (south and west) decimal numbers, with the decimal portion simply representing the share of a full degree left over. Boulder's coordinates under this system are thus 40.014984, -105.270546, meaning that 0.105 degrees is the same distance as 0' 53.9".As per wikipedia,The haversine formula determines the great-circle distance between two points on a sphere given their longitudes and latitudes. Important in navigation, it is a special case of a more general formula in spherical trigonometry, the law of haversines, that relates the sides and angles of spherical triangles. For final bearing, simply take the initial bearing from the end point to the start point and reverse it (using θ = (θ+180) % 360). Copy link Quote reply marioidival commented May 12, 2014 If i want use with miles? radius can be 3959?

TL;DR - By making a few geometric assumptions, the Haversine formula provies an exceptionally simple way of calculating distance between two latitude/longitude pairs. Because of this I ended up writing my own Python module for calculating the distance between two latitude/longitude pairs If you know your exact latitude and longitude and the coordinates of a second point on Earth, you can use on online calculator such as the NOAA tool in the Resources to find out exactly how far you are from that point along the shortest path. You may not be able to drive that way, but it's fun information to be able to know regardless!

"> const Δψ = Math.log(Math.tan(Math.PI/4+φ2/2)/Math.tan(Math.PI/4+φ1/2)); const q = Math.abs(Δψ) > 10e-12 ? Δφ/Δψ : Math.cos(φ1); // E-W course becomes ill-conditioned with 0/0 // if dLon over 180° take shorter rhumb line across the anti-meridian: if (Math.abs(Δλ) > Math.PI) Δλ = Δλ>0 ? -(2*Math.PI-Δλ) : (2*Math.PI+Δλ); const dist = Math.sqrt(Δφ*Δφ + q*q*Δλ*Δλ) * R; Bearing A rhumb line is a straight line on a Mercator projection, with an angle on the projec­tion equal to the compass bearing. Two imaginary sets of lines - the longitudes and latitudes - drawn around the world to make a grid, give us the geographical co-ordinates of any place. The region between these two, centred on the Equator, is the Tropical region. Some of the countries which fall in the Northern hemisphere are; the..

The shortest line between two lines is perpendicular to both. Thus the vector representing the shortest distance between AB and CD will be in the same direction as (AB X CD), which can be written as a constant times (AB X CD) You may receive emails, depending on your notification preferences. Shortest distance between two line segments. Function computes the shortest distance between two line segments. 4.2 φ1, λ1, θ13 : 1st start point & (initial) bearing from 1st point towards intersection point φ2, λ2, θ23 : 2nd start point & (initial) bearing from 2nd point towards intersection point φ3, λ3 : intersection point The dierence between estimated distance and true distance is approximately 1e − 04. Although that might not seem signicant, it was for the person running the physical simulation. Notice that the true closest parameters occur for s = 1, not for s = 0. Whether or not this makes a dierence depends on.. In simpler term, latitude lines run from the North poles to the South poles while longitude lines run from the East to West. Zero The latitude is also known as the Equator, while the zero Longitude refers to the vertical lines that will show the distance between the left and right portion of the earth Distance between two 3D lines. ▲.
