  5. 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
  6. April 9, 2018 – MRO HiRISE Updates - MRO HiRISE EDR, RDR, DTM and Anaglyph data products released through March 5, 2018 (Orbit 54,399) See https://wufs.wustl.edu/ode/odeholdings/Mars_holdings.html
  7. CRISM analysis In CAT

    Hi Feng, I use both ENVI 5.4 standard and classic version (whichever works well) and for this instance, I used classic one. I copied the three projections files and now it works, does not show any "Header Error'' message. However, the projected image does not match with map context. Hope to hear back from you soon. Thank you, Emran
  8. 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
  9. CRISM analysis In CAT

    Dear all, I have been trying to use CRISM TRDR (trr3) image of ''FRS0002AEAB_01_IF167L_TRR3'' and ''FRS0003012C_01_IF167L_TRR3'' using CAT in ENVI. However, after standard corrections (ATP), I tried to project the image cube using ''Project Single Cube Data'' option. I got a projected image of bad shape which does NOT match with map context image and kml shape (attached the screenshots). I guess only a part of the image was projected. Also, CAT showed a message after performing the processes (attached also). Can anyone please let me know how can I fix the problem? Thank you, Emran
  10. ODE - LRO Release 33 Loaded into ODE

    April 2nd, 2018 Updated Diviner RDR query tool database from July 5th, 2009 to December 15th, 2017.
  11. Georeferencing PDS images in ENVI

    Hi Subhabose, The ‘ellipse.txt’ file looks fine to me. In datum.txt, you had an extra ‘,’ in the last line. The correct string would be below. ‘D_Moon_2000, GCS_Moon_2000, 0,0,0’ In file ‘map_proj.txt’, I saw your definition for the Moon North Polar Stereographic projection. Since the maximum and minimum latitude for your data are 59.676 and -1.151 degrees, I would not suggest using the North Polar Stereographic projection.
  12. Georeferencing PDS images in ENVI

    Hi, I have attached the map_proj.txt, datum.txt and the ellipse.txt files with the updated strings. The image I am using is M3G20081229T022350_V01_RFL. datum.txt ellipse.txt map_proj.txt
  13. March 27th, 2018 - More MEX HRSC RDR Version 3 Data Loaded into ODE HRSC new radiometrically calibrated (RDR version 3) image data have been loaded into ODE, with coverage through October 14th, 2016 (Orbit 10-16200). See https://wufs.wustl.edu/ode/odeholdings/Mars_holdings.html
  14. Georeferencing PDS images in ENVI

    Hi Subhabose, The product ID you gave was not a complete product ID. This value can be found in the product label file. From your ID I cannot tell what type of product you used. Is it the L0 raw data, or the L1B calibrated image, which has 3 versions, either Version1, V2 or V3? Or the L2 reflectance image? Please take a look of below help page. At the bottom of the right panel, you will see some additional M3 resource, including M3 ENVI User's Guide,working with M3 Data, Working with M3 L1B Data, M3 Data Tutorial and a few others. http://ode.rsl.wustl.edu/moon/pagehelp/quickstartguide/index.html?isros_chandrayaans_m3.htm Assuming you use the Version3 L1B calibrated image, e.g., ' M3G20081229T022350_V03_RDN', you can access the location and geometry information in the *.LOC and *.OBS files and relate it to the spectra of the *.RDN files using ENVI as documented in the file 'M3 ENVI User's Guide'. And you can use GLT in ENVI to do the georeference. As for your question about map projection, from your screen copies, I can only tell the Datum you used are not correct. Because WGS-84 is used for Earth. If you can send me the strings that you have updated in three files datum.txt, ellipse.txt, map_proj.txt, I can dig more into your issues. Thanks, June

  16. Georeferencing PDS images in ENVI

  19. I want to georeference an M3 image (obtained via PDS) in ENVI. I was following "Assigning Map Information to PDS Images in ENVI", posted by Dr June Wang. I was able to perform most of the steps. Yet when the process is complete, it seems that the georeferencing is not correct. I have attached a couple of screenshots from the M3 image I was working with. To check the accuracy of georeferencing, I cross-checked the location from Google Moon and found that there are a lot of discrepancies between the 'georeferenced' M3 image and Google Moon. In the 'Edit Map Information' window, I entered X-pixel and Y-pixel sizes as 140. Please let me know if this is correct. When I cross-checked with Google Moon, the top of the image should have latitude as north and the bottom the image as south (also verified from LOC file of the M3 image). Please help.

  24. 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
  25. CRISM Analysis in CAT 7.3.1

    Hello Feng, No, the file which is used for spectral enhancement in getting ratio spectra (part in spectral analysis and interpretation). I attached the manual and indicated it in a red box. Is ''same detector un-map-projected'' same to the image cube product after ATP correction (...._trr3_CAT_corr.img)? I tried collecting spectra as denominator from that file (un-projected one) and collected numerator spectra from the projected one. Then I tried to do spectral math (numerator/denominator) with these spectra(s). But ENVI shows an error message like spectral bands do not match for numerator and denominator (number of bands do not match). When we project the image cube, has there any changes in the number of bands from unprojected one to projected one? Thank you, Emran
