Re: [ferret_users] How to add a symbol on a map

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi,
Just to expand on Hein's answer a bit. If the locations are in two variables xpts, ypts, it looks like this

! make a map (or just plot some XY data)
yes? go basemap x=150:290 y=-70:0
yes? plot/over/vs/symbol=20 xpts, ypts

! or use the polymark script for filled polygon shapes.  To see how it works,
yes? go/help polymark 

In Ferret v6.84, if the x-location data has units of longitude and the xy plot has an x-axis in units of longitude, Ferret will apply a modulo translation and locate the marks on the map even if the map is, say 0:360 and the x-locations are listed in -180:180 for instance.

I was wondering how I can show station locations on a map using symbols.

plot /overlay /symbol=20 /color=blue {4.5,7.3},{50.3,52.6}


will plot 2 symbols, one at 4.5,50.3 and one at 7.3,52.6 .  
You can use the label command to also add station names.

Kind regards,
