calculate values within a vector 1032 0
Started by Deleted User
I am very much a beginner at programming but would like to calculate the values of a raster within vector area for many images. Does anyone have a script that can:
-Open a shapefile
-Open many rasters
-Calculate the mean and standard deviation of those rasters within the shapefile region, but is able to ignore areas of zeros or NoData
-Output the mean and standard deviation to a table which lists all the results together
Any help is greatly appreciated! Thanks!

multi-core CPUs and IDL 1345 1
Started by Deleted User
Hi,
&160;
I've been using IDL 6.4 (64-bit) for a while using my department's license on a machine with an intel dual-core processor running RedHat. IDL doesn't seem to be able to utilize both processors on this machine, my CPU load never exceeds 50 even when I'm running that takes hours to calculate (in my procedures, the CPU is definitely the bottleneck). When running long computations the CPU load will hover around 100 on one processor, and then at random times just switch to being 100 o...

Serial Communication - Help Wanted 1067 1
Started by Deleted User
Good Morning Everyone,
This topic is about using the SERIAL Port Input/output DLM that is available for download.
As, some of you already notice it, this plug-in is not anymore working for the last verion of IDL.
In the post "Serial" by shenanigans, ITT support answer that "...The dll and dlm will need to be set up to work with the IDL release.&160; The author included the C source file so a new dll and dlm should be able to be compiled for use with IDL 71."

Error opening file 3730 2
Started by Deleted User
Hi,
First of all sorry because of my English. I have just install the 7.1 IDL version on my Ubuntu 9.04 and there is a problem. I am trying to run some of the programs I have done with an older version. If I compile them with IDL DE everything it's all right but when I try to work with the console it appears:
IDL> .rnew AjusteLor
Error opening file. File: AjusteLor
The error seems so stupid and I think is due to a misconfiguration of the IDLWorkSpace but I don't know what to do.
Thank y...

Create array with IDL's internal API 1229 0
Started by Deleted User
Hello,
I'm writing a bridge to IDL from C. I have currently got almost everything to work. However, what I can not figure out is how to neatly create an array variable through the interface defined in idl_export.h. I have only three options as far as I know:
1. Use Import(Named)Array to point to the data. However, this would only create a pointer to the data I have previously defined. I do not wish to do this, since it would mean that if the data is modified outside of IDL, it will also be mod...

BUG: wset doesn't remember window range 986 0
Started by Deleted User
I have encountered this bug in IDL.
you can use this code:
window,1
x=findgen(100)
y=findgen(50)
y=&91y,reverse(y)&93
plot,x,y,yr=&910,100&93,/ys
window,2
plot,x,y,yr=&910,150&93,/ys ;here you change the yrange
wset,1 ; here you call back window1, but NOT its yrange !!
oplot,x,y,color=100
If you look at the result the oplot is not the same, because it remembers the yr of window 2 and not wset,1.

I am running IDL7.0.8/ENVI4.6.1 on an OpenSuSE 11.1 machine and I've been having a few issues trying to get the licensing procedure working.

However, when I run IDL/ENVI as a normal user I receive an error message stating that it can't find the license, and will run in 7 minute demo mode. This does not happen if I run the program as root.

Bugreport: ABS does not work as expected 1420 0
Started by Deleted User
On IDL Version 7.0 (linux x86_64 m64) ABS does not work as expected. This has to do with the fact that IDL allows both 0 and -0 for floats and doubles.
Example:
IDL> print, 0., -0., ABS(0.), ABS(-0.)
Output:
0.00000 -0.00000 0.00000 -0.00000
Expected output:
0.00000 -0.00000 0.00000 0.00000
Reproducable: always
