Methods
findGeodesic(latA, longA, latB, longB[, max])
- latA - Float
- longA - Float
- latB - Float
- longB - Float
- max - Integer
If max parameter is excluded function returns the orthodromic distance between given coordinates a and b. Otherwise checks if orthodromic distance between a and b exceeds the max parameter and returns a boolean value.
findCentroid(latArr, longArr)
- latArr - Array
- longArr - Array
Returns geometric midpoint (arithmetic mean) given an array of latitude coordinates and an array of longitude coordinates.
interpolatePoints(latA, longA, latB, longB, distBetweenPoints)
- latA - Float
- longA - Float
- latB - Float
- longB - Float
- distBetweenPoints - Float
Returns geographical coordinates of a fixed distance apart (distBetweenPoints) along the direct path between two given points.
