Map Projection [message #86267]

Hello,

I'm trying to create a basic plot with a map of the US and trajectory data plotting on top. I'm trying to follow the map projection method using mapCoord = Obj_New('cgmap', 'Lambert Azimuthal', Limit=limit).

I keep coming across an ellipsoid statement in most of the examples I've found but I can't find any explanation as to what it is. Different examples have use ellipsoid=24, ellipsoid=19, ellipsoid=WGS84, etc...I don't know if I need this or how to set it if I do.

Can someone please explain what the ellipsoid statement is? And, is mapCoord=Obj_New('cgmap', ....) the best way to go about plotting a map of the United States? Thank you.

Sincerely,
Morgan
