Anautical mile was originally defined as the length on the Earth’s surface of one minute (1/60of a degree) of arc along ameridian(north-south line of longitude). Because of a slight flattening of the Earth in polar latitudes, however, themeasurementof a nautical mile increases slightly to...
lon1: number, lat2: number, lon2: number) => { const earthRadiusInKm = 6371; const dLat = degreeToRadian(lat2 - lat1); const dLon = degreeToRadian(lon2 - lon1); lat1 = degreeToRadian(lat1); lat2 = degree
= kilometers per degree of latitude difference; = kilometers per degree of longitude difference; where and are the meridional and its perpendicular, or "normal", radii of curvature (the expressions in the FCC formula are derived from the binomial series expansion form of and , set to the Cla...
The routines and formulas here consider negative latitudes to be South latitudes and negative longitudes to be West longitudes. While this may seem unfair to those of us living in the western hemisphere, what can I say other than deal with it!? A decimal degree value can be converted to r...

To showcase the methods, the sample will use a simple dataset that lists theLatitudeandLongitudevalues ofPrague, Czech Republic, andSalzburg, Austria. Method 1 – Using an Arithmetic Formula to Calculate Distance between Two GPS Coordinates
1)WGS 1984: The 15x15 degree graticule cells appear as squares. The map uses a modified Plate Carree projection to display the latitude and longitude values. Note that distances are very distorted in the east-west direction, north or south of the Equator. In this coordinate system, the North...
To translate miles into degrees find the narrow range, keep in mind that the Earth has , approximately 25,000 miles of perimeter, divide 25000 by 360 degrees which gives 70 miles per degree. If you want a range of 10 miles, your range in degrees will be at most 0.15 de...
set up as geographic longitude and latitude. Under dimensions, pick which dimension you used to create your parameter and drag it over to map. It should map all of those points automatically. Drag your “identifier” over to color. This is the calculated field you created in the last section...
