Maybe I missed something...but where does your readcol routine come from?
If it's the idlastro one that I'm using, the format statement isn't
something that I've seen before, so I tried it with your data:
------
IDL> readcol, 'dat1.txt', city, lat, lon, alt, format = 'A, 3F'
% READCOL: Illegal format 3F in field 1
% Error occurred at: READCOL 203
------
cheers

Yes, Chris! Readcol is from IDL_Astro... O.K. I will try : format =
'A, F, F, F'
David, What I want to do is to display altitude in 3d:
x = lon
y = lat
z = alt
and if it is possible, I want to present this on the Korean map...
I found the scatter3D routine in your website, and tried to do this
with it, but still not working. Please give me some suggestions.
