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,...

1 Replies and 1763 Views can WHERE function be maxed out?  1763  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

6 Replies and 1904 Views WorldView-2 Radiometric Calibration Batch Process  1904  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>
