7 Replies and 1798 Views Thor de-stripe and Spear vertical stripe removal  1798  7 Started by  JED Hello, I am trying to remove vertical stripes from an image. I have previously used THOR de-stripe with moderate success. However, this time the results produce a blank raster with all -Nan values. I've also tried to use SPEAR vertical stripe removal, with similar results. The mask highlights all pixels with a value at any mask value, and therefore I cannot complete the wizard to complete Spear destripe. The original image looks fine in Envi. I have verified that the original raster has va...

0 Replies and 824 Views Radiometric Calibration Processing  824  0 Started by  Russell Ives I am using my own atmospheric correction method to determine bottom of atmosphere radiance of Worldview 2 data, and want to apply the radiometric calibration tool to convert the resulting image to BOA reflectances using the equation (pi.L.d^2)/(Esun.sin(theta)) as provided in the ENVI documentation. My routines remove much of the original metadata that came with the imagery. That documentation states 'If the input file does not contain metadata for reflectance gains and offsets, ENVI computes T...

1 Replies and 1078 Views IAR Reflectance Correction (and others)  1078  1 Started by  Jose Manuel Lattus Hello! Much time I ask myself why the IAR Reflectance Correction don't allow to use a mask file. Many images have borders and the IAR use the Mean Spectral of all Pixels, so it includes the border and the border have a lot of influence are many pixels (ASTER/LANDSAT)... I think this correction will be better is you only consider the pixels with information. In the same issue, if you previously edit the envi header and set the ignore value to 0 (for example), this will ignore the borders in a ...

2 Replies and 935 Views Mosaic  935  2 Started by  Z Z Hi,everyone. I have downloaded several Sentinel-1 images, then I made radiometric terrain correction and convert DN value to dB. The first mosaic is made by using of two processed images in ENVI. and land area is also be removed.The masked mosaic output's size is about 4.8 G, and then two masked mosaic images( one individual mosaic image size is about 4.8G) are be made second mosaic. However,the process is very slowly this time. About 17 hours later, the mosaic is only about 75. My quest...

2 Replies and 806 Views ROI  806  2 Started by  Z Z Hi,everyone. I have create several different ROIs in an satellite image,and I want to get the statistics of every different ROI's mean value rather than overall ROI's mean value.I have found XROI in IDL can show individual samples’ information, however these information couldn't be saved into files.So I want to know the way to get the goals. Thanks for your suggestions in advance.
