#1 | fixed | Automatic CASI RGB TIF production | mggr | mggr |
Description |
Currently, the batch files output a fixed set of bands (2, 3, 5). This won't work for the dynamic bands in CASI. We need a small utility to pick out the 3 bands closest to RGB from an HDF file. |

Two issues:
Rachel's initial contact email: I am trying to process ATM and CASI data flown last summer over my two sites in Wales (GB06/05, PI - Tim Malthus). Unfortunately we are having a few problems with AZGCORR and I wanted to check whether you had encountered them before and had any idea what might be wrong (or who else might have). As we are carrying out atmospheric correction before geometrically correcting the swaths in AZGCORR, so we are using the resulting .bsq image in conjunction with the original .hdf (and a DTM) as inputs to AZGCORR, as recommended in the user guide. With the CASI data and most of the ATM swaths this appears to work ok (at least as far as can be determined by visual inspection of the results), however with certain swaths the geometric correction is not successful. These seem to be swaths with considerable numbers of missing pixels / scan lines. When the raw .hdf data is geometrically corrected directly, the problems do not appear and AZGCORR works correctly (attached jpeg1), but when the image is first converted to .bsq and atmospherically corrected the image seems to be corrected up until the point of the missing scan lines, but after that appears to be just 'stretched' to fit the correct outline (jpeg2). The same problem is also being encountered by John Dowens in correcting strips from GB06/07. Do you have any ideas what may be causing this problem? Any suggestions very much appreciated. I was also wondering if you know when I might be likely to receive the remaining LIDAR data from this acquisition (I have the lidar from my Glasfynydd site but not from Clocaenog)? |
