ENVI ROI to Image Doit 1912 2

I know it is a bit antiquated to be using DOITs but such is the process.I'm trying to use ROIs to edit a class image, to do this I need to convert my ROIs to images. I've successfully used envi_restore_rois and envi_get_roi_ids, to access my file associated ROIs. The trouble lies in, that I want to make two class images from the restored ROIs. One class image that will have ROIs 1 and 2, this one will always be written by the program. If there there is a 3rd ROI, it needs to be a separate image,...

Plot multiple crosshairs 2003 2
Started by Deleted User
Hello!
Is there a way to plot multiple crosshairs in one plot I tried something like this:
p=plot(array)
c1=p.crosshair
c1.location=&91somex,somey&93
c2=p.crosshair
c2.location=&91otherx,othery&93
Unfortenately, this will only plot the last crosshair (i.e. c2). Is there a solution to plot both
Thanks in advance!

can WHERE function be maxed out? 1912 1
Started by Deleted User
I am indexing large datasets (2239 by 880 pixels - not that large for remote sensing datasets) using the WHERE function, and counting the indexed pixels. My counts are clearly off, and I have the suspicion that the count cannot handle the large number. I read that count is a long integer, but googling I find conflicting information on the maximum number that a long integer can hold. Is there a way to get around this Is it only the count that is a problem, or the indexing itself

WorldView-2 Radiometric Calibration Batch Process 2126 6
Started by Deleted User
<p>I have a large number of WorldView-2 NITF images to batch process. The first step would be radiometric calibration to radiance (preferably) or reflectance. I tried using the ENVIRadiometricCalibrationTask to do so, but could not find an example code like the examples for Landsat 8 or QuickBird, and the results of my attempts to finish the code gave me poor results. Does anyone have a code or advice for how to batch radiometrically calibrate WorldView-2 NITF images</p>
