    MRO CRISM data Processing: Georeferencing

    Hi Chandan, It seems the customized datum is not recognized by ENVI. Would you please check if the three map projection files are in the right place? According to CAT installation document: Set up CRISM Customized Map Projection Move the CRISM customized map projection definitions files (datum.txt, geogcs.txt, spheroid.txt) from the CAT_ENVI\aux_files\crism_projection\ folder to your ENVI installed path inside the idl8x\resource\pedata\user_defined\ folder (the location of user_defined folder may vary based on your ENVI version, idl8x: idl86 for ENVI 5.3 and 5.4; idl87 for ENVI 5.5). If there files are not in the right place, please copy them to related folder and then start ENVI+IDL again. Thanks, Feng

    CRISM analysis In CAT

    Hi Emran, There is no problem for the map context and CAT projected TRR3 image. The map context is coming from DDR which contains all lines including the key area and lines before it reaches key area. CAT map projection removes the lines before key area. If you run map projection in ENVI (on standard 5.4: Geometric Correction -> Georeference IGM), you can see all lines as following: But the lines CAT excludes is not useful and that's why CAT projection cuts these lines. Also please note: this is typical for the FRS and ATO data. Hope this answer your questions. Thanks, Feng

    CRISM analysis In CAT

    Hi Emran, This is Feng. I am going to look into this. Have two questions: are you using ENVI 5.4 standard (not classic version)? Do you copy the three map projections files inside \CAT_ENVI\aux_files\crism_projection folder to your ENVi IDL folder (like C:\Program Files\Harris\ENVI54\IDL86\resource\pedata\user_defined folder)? Thanks, Feng

    CRISM Analysis in CAT 7.3.1

    Hi Emran, The image cube product after ATP correction (...._trr3_CAT_corr.img) has all original bands (438 which include 8 bad bands, you can see it through Data Manager in ENVI 5.4 ) When you project the image cube, these bad bands are removed, so there are 430 bands left. Can you do the spectral enhancement before map projection then projection the output afterwards? Thanks, Feng

    Hello Emran, Do you mean which file I used in the instruction? I use frt000047a3_07_if166l_trr3_corr_p_2014params_flat.img Thanks, Feng

    Hi Emran, I did replicate the error in classical ENVI. I will fix this problem. Meanwhile would you please use the recent ENVI CAT? Thanks, Feng

    CRISM Analysis in CAT 7.3.1

    Hi Emran, I want to double check with you that the error happened on ENVI classic version not the recent ENVI version? Like your previous post shows a processed flatten image in recent ENVI version. I will run the processing on the classic ENVi to see if the error shows up. Thanks, Feng

    CRISM Analysis in CAT 7.3.1

    Hi Emran, I never see this error before. So I try to see if I can replicate this error on my end with the data you are working on. It went smoothly without any error. See screenshot below. What is your ENVI version? Thanks, Feng

    CRISM Analysis in CAT 7.3.1

    Hi Emran, Would you please try to do the processing again to see if the error showing again? I want to check if the error can be replicated or just one time issue. Thanks, Feng

    CRISM Analysis in CAT 7.3.1

    Hi Al, I am here to assistant you to fix this issue. By tracking the error message you posted, it seems there is some problem with ENVI views. When you do the processing, how many views do you open? It may be too many views opened so ENVI throws out an OVERLOADEQ error. Thanks, Feng

    CAT 7.3.1 in ENVI 5.4

    Hi Al, I am ready to help. The problem to me seems an IDL_PATH issue. Would you please verify the following path in the idl.pref file (in default installation, it locates C:\Program Files\Harris\ENVI54\IDL86\resource\pref folder)? IDL_PATH: + C:\Programmi\CAT_ENVI;<IDL_DEFAULT> If there is no such statement in this file, would you please add it? Let's me know if you do see this path. Thanks, Feng Friday at 10:31 AM Edit Report Al Emran Hi Feng, Thank you for the reply. Yes, I have solved the problem. Thanks, Emran Sunday at 04:16 PM 0 Report
