  1. Last week
  2. The PDS Geosciences Node and the LROC Data Node have established a faster data transfer method. As a result, ODE cart downloads of LROC data will be fulfilled noticeably faster than in the past. We encourage users to give it a try through the Lunar ODE website.
  3. July 11th, 2019 - New Extended Mission 5 MEX MARSIS Active Ionospheric Sounder (AIS) Data loaded into ODE. - Updated MEX MARSIS RDRAIS products released through December 31st, 2016 (Orbit 1844-16468) See https://wufs.wustl.edu/ode/odeholdings/Mars_holdings.html
  4. I'm currently doing thermal analysis for lunar landers and would like to use measured surface temperature in a landing zone (which looks like it would be in the level 4 data). What is the simplest way to go about this? Any help if very much appreciated.

  6. July 8th, 2019 - Loaded MRO SHARAD RDR backlogged data for releases 27-35 from March 10th, 2013 (2013-069) to May 16th, 2015 (2015-136) into ODE. Please see ODE Mars Holdings – https://wufs.wustl.edu/ode/odeholdings/Mars_holdings.html
  7. July 5, 2019 – MRO HiRISE Updates - MRO HiRISE EDR, RDR, DTM and Anaglyph data products released through May 31, 2019 (Orbit 60,199) See https://wufs.wustl.edu/ode/odeholdings/Mars_holdings.html
  8. July 5th, 2019 - Mars Odyssey Release 68 Data Updates Loaded NS and HEND raw and derived data into ODE through December 30th, 2018 Updated THEMIS standard data products (IREDR, IRRDR, IRBTR, VISEDR, VISRDR and VISABR data) from February 19th, 2002 to December 5th, 2018 Updated THEMIS geometry data products (IRGEO2, IRPBT2, VGEO2, and VISALB data) from September 28th, 2013 to December 5th, 2018 See https://wufs.wustl.edu/ode/odeholdings/Mars_holdings.html.
  9. SHARAD RDR data from the ASI team members have been posted, covering previous MRO releases 27-35 (through May 16, 2015). The team is recovering data from deliveries that were missed due to a hiatus in ground operations. See ERRATA.TXT for details. The data are available on the PDS Geosciences Node's SHARAD page.
  10. July 2nd, 2019 Updated LOLA RDR query tool database from July 13th, 2009 to May 1st, 2019
  11. Hi Feng, Some of the scenes that i've checked are: FRT000064D9_07_IF166J_MTR3 FRT000064D9_07_IF166J_TER3 FRT00009786_07_IF165J_MTR3 FRT00003E12_07_IF166J_MTR3 FRT00003E12_07_IF166J_TER3 FRT00008389_07_IF166J_MTR3 FRT000094F6_07_IF166J_MTR3 FRT0000634B_07_IF163J_MTR3 HRL000119C7_07_IF181L_TRR3 The big part of them were on the MICA files, i've tried to replicate the results from there as a starting work since i have not much expertise with this kind of data treatment. Thank you, Wladimir
  12. Hi professor Arvidson, The exact scene product is the: FRT000064D9_07_IF166J_MTR3. I've tried emulate the results from the MICA files example, but without success. This image shows the ROI's location for the numerator (X:174, Y:529) and denominator (X:110, Y:529). This second, the mean spectra for the numerator and denominator: And this is the resulting spectra (smoothed) from the ratioing process, which is pretty different from the MICA files example: Any advice for the procedure or if you detect something wrong will be very helpful. Thank you so much, Wladimir
  13. June 28th, 2019 Updated LOLA EDR products from June 18th, 2009 to May 1st, 2019 Updated LOLA RDR and GDR products from July 13th, 2009 to May 1st, 2019
  14. Release 38 of Lunar Reconnaissance Orbiter data is now online at the Geosciences Node. This release includes new data acquired between December 15, 2018, and March 14, 2019, for most data sets. Data can be reached from the Geosciences Node LRO page. The Lunar Orbital Data Explorer allows searching and downloading of LRO data.
  15. New functionality has been added to the ODE product search page to allow users to select a freehand polygon location for coverage searches. Similar freehand polygon search filtering has been added to the map search page.
  16. A laboratory shocked feldpars bundle from Jeff Johnson (JHU APL) is released. This bundle consists of data acquired from thin sections created from a suite of experimentally shocked plagioclase feldspars.
  17. Mars Odyssey Release 68 includes new GRS data. The new Raw data (EDR), Derived Neutron Data (DND), and Derived HEND Data (DHD) products cover the period October 1 through December 31, 2018. The new Averaged Neutron Data (AND) and Averaged HEND Data (AHD) products cover the period September 23 to December 30, 2018, which is Ls=255 to 315 in Odyssey mapping year 09. The data are online at the PDS Geosciences Node at http://pds-geosciences.wustl.edu/missions/odyssey/grs.html.
  18. June 24th, 2019 - LRO Release 38 has been loaded into ODE.

  19. Hi there: Would you please let me know which MTRDR scene you have been examining and I will take a look at the data and spectral plots and then answer your questions. Ray Arvidson PDS Geosciences Node Manager and CRISM Science Team Member
  20. R/Rc is the ratio of the actual reflectance spectrum to the continuum spectrum (basically a straight line connected over the absorption band). ENVI has a Continuum Removal tool (see https://www.harrisgeospatial.com/docs/ContinuumRemoval.html) which looks to me like it performs this calculation for you. If you start with the M3 reflectance images (files that end in "_rfl.img") and use the Continuum Removal tool, the result should be the ratio R/Rc for each band. Then you can use the Band Math tool to put together the sums needed to calculate integrated band depth. Note: I'm not all that familiar with M3 data processing, so you might want to confirm this is the right approach with someone from the M3 team before using this in any publications.
  21. Thankyou so much How to calculate R/Rc??
  22. Hi Wladimir, Would you please provide the scenes you worked on so that we can better go through from there? Thanks, Feng
  23. Hi Arpita, Just to confirm, you're looking at the formulas on page 4 of this paper, right? https://pubs.er.usgs.gov/publication/70034937 It looks like those are calculating the band depth (1 - R/Rc) at a number of adjacent bands, then adding them together to get the integrated band depth over a range of wavelengths; the variable 'n' is just used to indicate which bands are used in the calculation. So for the 1 micron integrated band depth, you'd calculate band depth at each of 789 nm, 809 nm, 829 nm, and so on, up to 1309 nm, and then add the results (with a similar calculation for 2 micron integrated band depth, just using different M3 bands in the sum). If you're using ENVI for your analysis, the Band Math tool should be able to help you calculate the band depth for each band that you're looking at, then sum up all of the results. John
  24. Hi dear community, I'm working primarly with MTRDR products for mineral identification using ENVI 5.3 + IDL with CAT 7.4 coupled and i have some questions: 1.- Why when i visualize the spectral profile for some scene in any pixel the profile shape is essentially the same only with changes on the data value?. Does that mean there's only one dominant phase per scene?. Even when i use the Browse Products and can distinguish more than one phase (colors) the profile for the default image (true color) keeps its form. I don't know if this is a coincidence for the scenes that i've analyzed or there is something wrong on the procedure that i'm following. 2.- It is enough the interpretation with the continuum removed function or the ratioing process is necessary?. I consider that isn't an easy task find an appropiate denominator ROI. I've tried to emulate some examples from the MICA files but i did not get the same results. 3.- About the custom stretching for Browse Products, when is neccesary fix the minimum value distinct to zero?. I understand that the maximum generally must be thw 99th percentile of the histogram, right?. 4.- How must be selected the right summary parameters for the "Custom Products" when the "Browse Products" are not good enough? Any help for any question will be very well received, thank you. -Wladimir
  25. Hi Everyone, I am Working with chandrayaan-1 M3 data and i want to calculate band depth for identify mineral. Plz help me how to calculate band depth and what is the value of n in the formula that is discussed by Mustard et al., 2011.
  26. hi Wladimir, I think the only difference between yours and mine is the data ignore value. Since you cannot change -1 to 65535. How about you directly open the .hdr file in NotePad and change -1 to 65535 then save the file? You need close the .img in ENVI otherwise, you are unable to save the .hdr file. Thanks, Feng
