Line between 2 points

[S.Nicolas - Webmaster]

Thank you Paul for your suggestion.
Unfortunately "equations" are not my best friend.
If somebody is willing to help or diirect me to an example, I will extremely
appreciate. I am using PHP/Mapscript.

Stephane,

to create a curved line between two points, you will need to calculate
intermediate points along the curve and add them to your line segment.

If you are portraying a straight line (geographic) in a non-geographic
projection then the calculations are simply to add intermediate points along
the line and mapserver will re-project them appropriately, ending up with a
nice curve (depending on the number of points).  If you are trying to
display a curve in the same projection, you will need some equation to
calculate points along the curve.

Cheers

Paul
