0 Replies and 5 Views Radiometric Calibration Processing  5  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 564 Views IAR Reflectance Correction (and others)  564  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 ...

1 Replies and 338 Views rigorous orthorectification  338  1 Started by  Francesca Marchetti Hi!i'm trying rigorous orthorectification with ENVI, i have two WorldView images and a DEM, all in TIF file format. I run all the steps but at the end the software can't complete the process, as 'rigouros orthorectification can't complete, the procese failed'. Someone can tell me what is the problem Do you know if i have to save the output file in a particular format Thank you !

2 Replies and 641 Views Mosaic  641  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 510 Views ROI  510  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.
