[ncl-talk] orthographic projection

[Matthew Fearon]

Dear NCL users,

I've created the attached orographic map using a slightly modified version of the topo_9.ncl example found here

https://www.ncl.ucar.edu/Applications/Scripts/topo_9.ncl

I was curious how/if I could apply the following adjustments:

1. Turn off the map perimeter box; mpPerimOn=False seems to be ignored

2. Add a few lat/long labels; pmTickMarkDisplayMode="Always" also seems ignored.

Below is a snippet of my resources used.
thanks,
Matt

;---Overlay everything to create the topo map

  overlay(redMap, greenMap)

  overlay(redMap, blueMap)


  return(redMap)
