Fig. Ideally, a three arc-second grid cell on the north edge of the Concrete sheet measures 60.75 meters along its north side and 92.60 meters along its east and west sides. latitude and longitude), you will only be accurate to around 1 km. 0.01° = 1.11 km (2 decimals, km accuracy), 0.000001° = 0.11 m (7 decimals, cm accuracy). } else { function calculateArc(){ m = meters/val; What is the rising action of faith love and dr lazaro? alert('Arc-Seconds value is required'); Earth is not a sphere and therefore the calculation is only a approximation valid at sea level. Example 60° latitude and 1 arc second: cos(60) * 30.866666667 = 0.5000000000000001 * 30.866666667 = 15.433333333500004, function calculateMeters(){ 1 arc second '' at equatorial sea level = 1852m/60 = 30.86666667m, Formlua: cos(degree latitude) * (1852/60) This script will calculate the length of one degree of both latitude and longitude, for a specific latitude. var arcs = document.getElementById('arcseconds').value; At 49 degrees north latitude, along the northern boundary of the Concrete sheet, an arc-second of longitude equals 30.87 meters * 0.6561 (cos 49°) or 20.250 meters. document.getElementById('arcs').value = arcs; } else if (lat === ""){ 1 degree° = 60 arc minutes ' document.getElementById('arcm').value = m/60; document.getElementById('arcm').value = arcs/60; While Why don't libraries smell like bookstores? A minute of arc is π/10800 of a radian. Does Jerry Seinfeld have Parkinson's disease? At the equator for longitude and for latitude anywhere, the following Lengths for both are calculated in nautical miles, statute miles, feet, and meters. Enter the specific latitude. document.getElementById('km').value = meters/1000; Convert arc seconds to meters or meters to arc seconds at a specified latitude. Example 45° latitude and 1 arc second: cos(45) * 30.866666667 = 0.7071067811865476 * 30.866666667 = 21.82602931286047 An arc second is an angle measurement (1/3600th of a degree). Approximate Metric Equivalents for Degrees, Minutes, and Seconds. Approximate Metric Equivalents for m = m * arc; this is adequate for rough locations on a global scale, for detailed work it Degrees, Minutes, and Seconds. document.getElementById('degree').value = m/3600; if (arcs === ""){ For other latitudes multiply by cos (lat). if (meters === ""){ When did organ music become associated with baseball? will be inadequate. document.getElementById('arcs').value = m; Example   0° latitude and 1 arc second:   cos(0) * 30.866666667 = 1 * 30.866666667 = 30.866666667 A second is 30.9 meters. It is a measurement of angle (1/360th of a full rotation) and although not an official SI unit it is an accepted SI unit. alert('Latitude value is required'); A minute is 1853 meters. }}. !Degrees, Minutes and Seconds to Distance A degree of longitude at the equator is 111.2 kilometers. //var arc = arcs * 30.866666667; A second is 30.9 meters. Download 1 arc-sec tiles and contours EPSG:4326. s = R θ. var lat = document.getElementById('lat').value; The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. If you know this, then you can use the formula. Since one degree is 1/360 of a turn (or complete rotation), one minute of arc is 1/21600 of a turn. A minute is 1853 meters. var arc = arcs * 30.866666667; A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol $${\displaystyle '}$$, is a unit of angular measurement equal to 1/60 of one degree. var val = m * 30.866666667; } else { // hier weiter Enter Meters: or Arc-Seconds: Enter Latitude: m km arc-seconds arc-minutes degrees Calculate Meters Calculate Arc-Seconds } Degrees. document.getElementById('m').value = m; m = Math.cos(m); All Rights Reserved. document.getElementById('km').value = m/1000; Copyright © 2020 Multiply Media, LLC. m = Math.cos(m); This is applicable for both a marine or aviation application, and the default is for "mid-latitude". The nautical mile was originally defined as a minute of latitude on a hypothetical spherical Earth, so the actual Earth circumference is very near 21 600 nautical miles. var lat = document.getElementById('lat').value; alert('Meters value is required'); If you are 13 years old when were you born? Degrees, Minutes and Seconds to Distance A degree of longitude at the equator is 111.2 kilometers. } approximations are valid: If you report a position to the nearest 0.01°  (two decimal places for } else if (lat === ""){ it is possible! var m = lat * Math.PI / 180; Earth is not a sphere and therefore the calculation is only a approximation valid at sea level. The degree is properly referred to as an arc degree, or a degree of arc. var m = lat * Math.PI / 180; 1 arc minute ' = 60 arc seconds '' 1: Schematic presentation of decrease toward the earth's poles. Ano ang Imahinasyong guhit na naghahati sa daigdig sa magkaibang araw? document.getElementById('m').value = meters; In order to convert this to a distance, you would need to know the radius of the circle (in meters) over which you are rotating.
