I am attempting to create Hovmoller diagrams using NetCDF data from satellite images. Has anyone done this before and if so, some pointers would be helpful. My data is as follows (for a sample of two files):
temp=ARRAY&912000,2000,2&93
lon=ARRAY&912000,2000,2&93
lat=ARRAY&912000,2000,2&93

Thanks for your help

IDLDE Crashes once loaded 1773 1
Started by Deleted User
When I run idlde (8.3) with the hot fix under Linux. The DE shows up and then crashes with this error message in the terminal:
Problematic frame:
C &91libpthread.so.00x10eb8&93 __lll_unlock_elision0x18
I am running Arch Linux which tends to run the latest packages and that library is linked to glibc.
IDL works normally otherwise.
Any suggestions

Hello, I'm trying to run a code and it calls in a procedure. the execution is halted , because it says "Attempt to call undefined procedure/function".

I can exit IDL and re-open it, and my Play button is back, but I was hoping someone knew a quicker way.

H5A_* increasing slowness 2399 1
Started by Deleted User
I am creating an object to parse the metadata in HDF5 files in a manner similar to H5_Parse. One difference, though, is that all groups, attributes, datasets, etc. remain open until the object is destroyed. I am parsing many files. If I parse them individually, closing each one before parsing the next, execution time increases linearly with the number of files. If I parse all files at once (closing only after all have been parsed), however, the H5A_* routines taking an increasing amount of time....

Newbie Question 1824 1

Hello,
I am literally just getting started with IDL so forgive me for making any seriously obvious mistakes. I am just running a few batch examples from the ENVI Reference Guide. I've just copied and pasted the CROSS_TRACK_CORRECTION_DOIT example into the IDL DE, save it, compile it, and run it. It seems to compile successfully and run through the couple of print statements I threw in for understanding. But it doesn't create a logfile or an output image. I know this is probably something ex...
