  3. We were contacted by a user who are looking at the tectonics and gravity of the Tharsis Rise region of Mars. She mentioned that she has “run into a problem analyzing some PDS data that I can't find a way around. After many days of trial and error (which was not aided by the fact that I have very little computer science experience), I was hoping you might be able to help. I'm trying to view and analyze the GMM-3 Mars gravity models, which are .IMG files (PDS listing). I don't have access to ENVI, so I've been trying alternatives, and have had the most success with the USGS's ISIS softwar

  6. Hi Maeve: ENVI is the main way that researchers process CRISM data, including mapping mineral parameter maps. Do you have access to ENVI? And do you know which CRISM scenes you would like to use? I can tutor you through using ENVI and CRISM data, but first let me know if you have access to ENVI software.

  7. Hello, I am a fourth year Geology student, and for my research project I am doing a comparison of Martian and Terran Alluvial Fans. I'd like to use CRISM data to display the mineralogy of fans in craters. However, the way I was planning on doing this was using ArcMap to show intensity of pixels in bands. I'm not sure if this is a valid methodology and I'd appreciate any advice on how to go about displaying mineralogy. I understand that analysis can be done using ENVI, but I've not had any experience with this. I would also say I'm just about competent in using ArcMap. Thank you!

  9. February 10, 2021 – MRO HiRISE Updates - MRO HiRISE EDR, RDR, DTM and Anaglyph data products released through January 4, 2021 (Orbit 67699) See https://ode.rsl.wustl.edu/odeholdings/Mars_holdings.html
  10. Yes, ArcGIS has better projection engine defined. And ENVI used ArcGIS projection engine in its application. The steps 3-9 you mentioned are actually based on ENVI classic interface. That blog was written years ago. After that there are many new release of ENVI, and its current version is 5.6. I don’t know which version you are using now, probably something 5.4+. If you are using a newer version of ENVI interface, one way to add the spatial reference is to find “Edit ENVI Header” under “Raster Management” in the toolbox as shown below in the right. You can add spatial reference from there. Ins
  11. Dear Dr. June. Thank you very much for your quick answer. I’ve been working the whole day on this little project and two situations have developed: 1.- I’ve read the post you provided (Thank you very much I also read Getting ENVI to read your PDS image correctly). 2.- I changed my subject of study and objective. Now I'll be trying to estimate the age of Enceladus' northern pole with the Buffered Crater Counting Technique. I'll be doing it with the help of ArcGIS' add-ins CraterTools & CraterStats. This is the best image of the features I was able to find. I uploaded th
  12. Hi Lex, Here is the post. If you still have problem, you can send me a sample image of both data sets. I haven't work with Europa or Io data before, but I can take a look. Thanks, June
  13. Hi, good morning. When working with PDS Europa or Io images of the Galileo SSI, how should I georeference my images? What projection should I use? I was looking for the Dr. June Wang's Assigning Map Information to PDS Images in ENVI post for reference, but I was unable to find it. Thanks in advance.

  21. See attached paper, Section 5.3, for what we do for thresholds for parameter maps. Choosing a neutral spectrum is a case of trial and error. I do not do this, rather I just look at the volcano scanned spectra for features such as the 2.3 um metal-OH absorption. Ray Arvidson Viviano-Beck_et_al-2014-Journal_of_Geophysical_Research__Planets.pdf
  22. as it is mentioned here that choosing denominator will be similar size spectrally neural dark area nearby numerator. what is the reason of choosing area nearby numerator ? why we are not taking any dark material throughout the images? and how we are getting stretch limit for each of summary parameter?

  26. Hello sir, I am Priyanka Kumari PhD scholar working on CRISM data set using machine learning. The MTRDR data wavelength tab file (frt000094f6_07_wv166j_mtr3) contain wavelength for two detector ,but some band are repetitive (for example band no. 284 in VNIR detector has wavelength 1010.18nm but same band no. 284 for IR detector has 2060.04). (1)So, for band no. 284 which wavelength to consider? (2)how the image are combining that same band number has different wavelength? wavelength to consider?
  27. DISORT is a generally applicable radiative transfer program and is available over the internet. We use a front end that is Mars specific. It is incredibly complicated and not meant for distribution. May I suggest that unless you wish to do Hapke-related nonlinear modeling of mineral grain sizes and phases you just stick to what CAT offers. Except for our group very few researchers try and use DISORT in their CRISM data analysis. Ray Arvidson CRISM Team Member PDS Geosciences Node Manager
