Hi,
I am totally new in developing apps with the AppStudio and qml, so hopefully the questionis not too easy.
I want to calculate the distance and the azimuth (bearing) from my current (gps)-position to a point on the map.
What i already did:
I added a positionDisplay to my map.
positionDisplay {
compass: Compass { id: compass
active: true
// Create a variable to hold azimuth
property double azimuth: 0
// Change sensor axis depending on 'userOrientation' property
axesOrientationMode: Compass.UserOrientation
onReadingChanged: { // Called when a new compass reading is available
compass.azimuth = reading.azimuth;
//Or better Call it when Reading is available?
//geoResult = locationPoint.geodesicDistance(toPoint);
}
}
positionSource: PositionSource { id: positionSource
active: true
onPositionChanged: { locationPoint.valid = position.longitudeValid && position.latitudeValid
locationPoint.x = position.coordinate.longitude;
locationPoint.y = position.coordinate.latitude;
geoResult = locationPoint.geodesicDistance(toPoint);
locationPointChanged();
}
}
}
The points are set like this
property Point locationPoint : Point {
property bool valid : false spatialReference: SpatialReference { wkid: 4326
}
}
property Location toPoint :Location{ coordinate { latitude: 55.314835
longitude: 8.458156
}
}
I thought I could use the GeodesicDistanceResult to get distance and azimuth, but it didn't worked.
GeodesicDistanceResult{
id:geoResult }
like in my "onPositionChanged"
geoResult = locationPoint.geodesicDistance(toPoint)
so what's wrong or how do i have to use it?
Thanks in advance!
Thomas
