distance

distance(X, Y)

X and Y can be a POINT scalar/pair/vector representing points in the coordinate system of earth.

Calculate the distance in meters between 2 points on the earth's surface.

p1 = point(180, 24.118418)
p2 = point(180, 24.11931)
distance(p1,p2)
// output
99.185916

p1 = point(117.60972, 24.118418)
p2 = point(117.50972, 24.118418)
p3 = point(117.70972, 24.118418)
p4 = point(117.75972, 24.118418)
distance([p1,p2], [p3,p4])

Calculate the distance between the two points p1 (Lon1,Lat1) and p2 (Lon2,Lat2) on the map. Based on the 0-degree longitude, the east longitude is taken as a positive value (Longitude), the west longitude is taken as a negative value (-Longitude), the north latitude is taken as 90-latitude, and the south latitude is taken as 90+latitude. So the calculation is:

p1 = point(-117.60972,24.118418)  //Longitude: 117.60972 W Latitude: 65.881582 N
p2 = point(117.61113,114.11931)  //Longitude: 117.60972 E Latitude: 24.118418 S
distance(p1,p2)
// output
6.02098E6
