Hi all,
First, many thanks for the help I've received in the past.
I'm trying to plot radar intensities on a map. The data
is supplied as 3 1-D arrays: latitudes, longitudes, and intensity values (0
- 10 relative units).
The following code snippet should illustrate what I'm trying to do...
After plotting a map, I plot the radar points, color-coded by relative
intensity,
using a do-loop: (some code below is omitted for clarity)...
Data:
lat 1-D array (NUMPT)
lon "
radar "
do i = 0, NUMPT -1
blon = lon(i)
blat = lat(i)
val = radar(i)
if( val .gt. 3.98 ) then
txtres@txFontColor = (/"red"/)
else
if ... etc... Set marker color by relative radar intensity value...
end if
text = gsn_add_text(wks, plot, "." , blon, blat, txtres)
end do
I'm finding for 1-D arrays of 40 - 50,000 points, the Linux system I'm using
takes upwards of 30 minutes to produce a plot. I'm trying to find a better
way to do this through Google searches, but I keep running into dead links,
etc.
Can anyone suggest a simpler, faster, alternative?
Thanks again...
