Hi 
Would someone be able to advise me the best way to do this?
I need to traverse from a Geography point, a distance of x (say 100m) to find that Geography point.
Is the best way to do this to project the origin point to x,y and then use some trigonometry to find the point 100m away and then unproject back to Geography?
Or am I overcomplicating things?
Looking at the Unproject method of MercatorProjection.cs, this always fails further down the line because longitude does not get set:
protected internal override void Unproject(double x, double y, out double latitude, out double longitude)
{
longitude = x;
if (y >= MaxY)
{
latitude = Math.PI / 2;
}
else if (y <= MaxY)
{
latitude = Math.PI / 2;
}
else
{
latitude = Math.Atan(Math.Exp(y)) * 2  Math.PI / 2;
}
}
fails here because longitude does not get set (to radians) above:
if (Double.IsNaN(longitude)  longitude < Math.PI  longitude > Math.PI)
{
throw new ArgumentOutOfRangeException("longitude", String.Format(CultureInfo.InvariantCulture, Resource.OutputLongitudeIsOutOfRange, longitude));
}
