In french: géoAzimuth

Returns the direction represented by a position in relation to another one.

This direction is expressed in angle format (clockwise in degrees) by taking the geographical North as reference.

Example

pos1 is géoPosition
pos1..Latitude = 1.442951
pos1..Longitude = 43.604363

pos2 is géoPosition
pos2 = GPSGetPosition()

InfoBuild("The direction is %1°", geoAzimuth(pos1, pos2))

pos1 is géoPosition
pos1..Latitude = 1.442951
pos1..Longitude = 43.604363

pos2 is géoPosition
pos2..Latitude = 2.505874
pos2..Longitude = 50.458744

InfoBuild("The direction is %1°", geoAzimuth(pos1, pos2))

Syntax

<Result> = geoAzimuth(<Position 1> , <Position 2>)

<Result>: Real

Direction (in degrees) in relation to the geographical North represented by <Position2> in relation to <Position 1> by taking the shortest way between the two positions.

<Position 1>: geoPosition variable

Name of geoPosition variable corresponding to the first position to compare.

<Position 2>: geoPosition variable

Name of geoPosition variable corresponding to the second position to compare.

Remarks

If <Position 2> is located South of <Position 1>, the execution of the following code returns 180:

geoAzimuth(Position1, Position2)
The calculation of the direction between the two positions is based on the WGS84 ellipsoid.
