File size constrain
|
| |
Hi, I have written a program to process .tif file in idl. When I run
the program over smaller sized files (~ 500 MB) it works
appropriately.
But, when I run it over a large file (~3 GB) the IDL crashes. A text
file is generated inside the workspace that provides an error message
'A fatal error has been detected by the Java Runtime Environment:'. I... more »

contour plot vertically stacked
|
| |
Hi.
I have to do a contour plot vertically stacked. I mean, I have data in
latitude and longitude at various height levels.
So, I'd like to plot these contour of lat x lon corresponding the
vertical levels on a single window. In this case, I'd have a vertical
perspective.
See you.

Using TV command instead of contour
|

Dear Friends, I have a data in form of flags, for example, dust=1,smoke=2 and so on. There cannot be numbers in between. The data is in the form of 2-dimensional array, with each cell corresponding to a latitude, longitude pair. I want to display it -- the output would look something like a chess board. If I use the... more »

Same Line Variable Definition
|
| |
Hello-I find it unlikely but is there any way to define multiple [let's say 4] variables on the same line? a=dblarr(10) b=dblarr(10) etc... This gets tedious if you need multiple empty arrays or zero variables for some reason, thanks!
