Plotting a track on a map.

all,

I have been doing a lot of work with X/Y plots but nothing so far with
actual maps, so my knowledge of this part of NCL is limited. I would like
to plot the track of an object on a map and I was wounding the best way to
approach this. I looked around and it looks like Polymarkers and Polylines
has the capability to do this but I was hoping someone has already come up
with a routine that does this sort if thing.

The idea is to have a list of LAT/LON pairs and to make an image of the path
overlaid on a world map with the particular LAT/LON points marked with a
date/time label.

Any advise is appreciated.

Thanks,

John Ertl
