Re: [las_users] Customizing LAS to plot vectors overlaid on shadedcontours

[Jonathan Callahan <Jonathan.S.Callahan@xxxxxxxx>]

Todd,

There are numerous places in the perl code where the number of variables 
is limited to two and detangling that code is a big job.  Getting 
vectors on top of underlays has long been a goal but we don't envision 
adding this functionality to the perl based LAS product server.  
Instead, we are developing a brand new all-java product server and 
rewriting all of the LAS Ferret scripts.  It is our hope that the first 
demonstration servers will be available next spring/summer.  
Unfortunately, you'll have to wait until then to get vector overlays.
