DAYMET data in IDL 1365 1
Started by Deleted User
A customer has written us with the following question about using DAYMENT data within IDL:
I am analyzing DAYMET data from mosaiced images for the entire western U.S. for the years 1993-2014 For 93-2012, I extracted values for 100 plots using lat/lons from ArcGIS and Python. I recently acquired 2013 & 2014 data but no longer have an ArcGIS license so I used IDL instead. As a test, I re-ran the extraction for one variable (precipitation) for 2005 in IDL to compare against the prior ArcGIS outpu...

Problem reading dicom data into some computers 1607 1
Started by Deleted User
A customer has an issue in which he is reading a dicom file with the code below using multiple systems:
image=fltarr(400,400)
fn=file_which()
image=read_dicom(fn)
print,max(image),min(image)
On some systems, the output is "1638 0" (which is the correct result) and on other systems, the output is "0 0" (the image is not being read correctly).

interpolate irregular 3D grid 1722 2
Started by Deleted User
Hi, I am trying to interpolate an atmopsheric model to an altitude grid, and I am totally confused by the interpolation methods, and just can't work out how to do it. I have:
lon = fltarr(144) ; 0 to 360
lat = fltarr(96) ; -90 to 90
alt = fltarr(144,96,66) ; calculated from pressure grid and so different at all points.
I want to interpolate other property arrays (144,96,66) onto the same lat/lon, and a specific altitude grid (alt_i = fltarr(66)).
Currently, I am simply looping...

Build Mask Based on One Bands&39; DN 2007 2
Started by Deleted User
Hi,
I would like to build a binary image from a range of DNs of a single band. I'm trying to isolate shadows (if it matters), I need to do a small manipulation to the mask before it is applied to the image, so I need to write the 'raw' mask to disk. I'm using the third band or Value band of the HSV image. This is my code so far, I will adapt it to batch File_Search, but for now I'm just feeding it a hard path to a test image.

the C language example of 'call_external' in IDL directory cannot works correctly in IDL 64bit versions(8.2 and 8.5 tested), but the same code can run correctly in IDL 32-bit versions(8.2 and 8.0 tested).

Batch Processing MTL&39;s 1830 3
Started by Deleted User
I need to process multiband MTL.txt files in a program that produces tif files from them that have reflectance data. The reflectance program only processes one MTL file at a time. I would like to batch process all MTL files in a folder, or several folders if possible. Similar to the proposition in this thread: http://www.exelisvis.com/Support/Forums/tabid/184/forumid/7/postid/17162/scope/posts/Default.aspx17162
How can I apply my program to the batch processing in the program in that thread

Suppressing ENVI windows 1520 2

I have an IDL script that is running through a collection of rasters. 95 of the rasters run through the script fine, the 5 that do not stall at a envi header info popup.

I am not too familiar with IDL, and am hoping that there I can raise an exception and then continue through the script.

IDL to Python Bridge - _iLocIndexer 1729 2

Histogram correlation 2481 11
Started by Deleted User
I'm trying to determine correlation values between 2 histograms that I have created with ENVI/IDL. The histograms I have created are made from single band images and my IDL script outputs stat reports but I am having trouble figuring out a process to run correlation between these 2 histograms.
The idea is to have one standard image histogram that I would check many other image histograms against in order to determine correlation between them. Can anyone push me in the right direction

&39;Tag name DOCLIP is undefined for structure IDLITMANIPVISVIEW&39; 2612 1
Started by Deleted User
Hello,
When calling the 'image' function in IDL 8.2, I sometimes get the following error:
"Tag name DOCLIP is undefined for structure IDLITMANIPVISVIEW".
Once it has appeared, the only solution is to restart the computer and sometimes I just cannot get rid of it.
Any help would be appreciated.
Thank you
