Rochdi Posted October 6, 2020 Share Posted October 6, 2020 Hello, Expert. I have downloaded CRISM TRDR dataset concerning Ritchey crater. Then, I've implemented CAT extension in order to do some photometric and atmospheric corrections as well. As known, the TRDR dataset broken out into two ranges: VNIR (0.3646 - 1.0560) and includes 107 bands. IR (1.0014 - 4) and includes 438 bands. I want to split up those ranges to Visible, Near-infrared and Short-wave infrared into these following wevelength: Visible (400nm to 700nm) Near Infrared (700nm to 1300nm) Short-wave infrared (1300nm to 3000nm) It means if I split up CRISM VNIR range into visible and NIR spectrums, the visible spectrum starts from band7 to band53 (band7: 0.4036 - band53: 0.7032) and the rest of VNIR bands will be considered as NIR spectrum. However, the NIR spectrum extends till 1300nm and VNIR's last band wavelength is 1.0560, meaning that NIR needs some additional bands to be completed. My question: Can I take some bands from CRISM Infrared range to come up with a complete NIR spectrum? Look forward to your reply, Rochdi. Link to comment Share on other sites More sharing options...
