Hi community, I'm working with ENVI 5.3 + IDL coupled with CAT 7.4 trying to process TRDR images (.trr3). I'm based primarly on the CRISM data processing workshop from 2012 and 2017 and my worksteps are as follows: 1.- Apply the ATM corrections with CAT to the images 2.- Apply de map projection fo the image 3.- Obtain the summary parameters image Nevertheless, I have certain doubts about this, so I would be very grateful if you can provide me some help please. My questions are: - Should I obtain the summary parameters and then apply the map projection or it is the opposite? - It is necessary the "ratioing" for the spectra and use the "Flatten summary parameters" option?. I've seen a post where its says that is enough the "Continuum Removed" option - How can i obtain a better resolution for the summary parameters image?. I've seen very good resolution images from papers that doesn't look like what I have obtaining (img_1) - When I create the summary parameters image the spectra doesn't look like the TRDR pure image because the data values change. Does that mean that I have to use the spectra from the TRDR and the summary parameters image is just like a "color guide" fot the mineral phases? (img_2) Finally, how can I use the summary parameters properly and elaborate mineralogical maps from they? Any help will be very appreciated, thank you. Wladimir wladimiracevedo@udec.cl img_1: The resolution that I'm getting from the summary parameters image after the custom stretch img_2: Spectra for the summary parameters image vs the original TRDR corrected image from the same pixel on both.

Glad to hear!

Tom, I truly appreciate the quick response. I realize this thread is three years old! We work with stereo pairs, creating stereoscopic LR and RL cross-view imagery. This site makes this much easier as you have the images already coupled. Thank you, your response makes sense and was helpful. Also, I would like to note that the instructions provided for using the measurement tools are very well presented. Nothing is vague and we truly, truly appreciate the time put in here on everything. Extreme value. Jimmy R

You are correct, Jimmy. The Mastcam L/R have different fields of view which can make working with the stereo pairs more difficult. The Notebook uses Navcam XYZ data products generated by the team to support the measurement and distance tools. However, the Mastcam team does not produce XYZ data products, thus the Notebook measurement tools can't support Mastcam images taken as stereo pairs.
-
Hello, Has the manner in which distance/scaling is determined via a tool been updated since this post? I do understand that a stereo pair is required, and Tom Stein gives a NAVCAM L/R as an example. Of course, those are considered stereo pairs. But you now have organized the L and R Mastcam images as pairs. I have not been able to activate the distance tool with these, though. Is is due to the fact that the L Mastcam images are wide angle, while the R shots are tight? Any help here is greatly appreciated. I am still learning my way around this site. Thanks, Jimmy R

Hi Aravind Bharathvaj, Yes, you can use below strings in ENVI. GCS_Moon_2000, 1737400.0, 1737400.0 -> set in file ellipse.txt D_Moon_2000, GCS_Moon_2000, 0, 0, 0 -> set in file datum.txt Please see the linked pdf file (https://lunar.gsfc.nasa.gov/library/LunCoordWhitePaper-10-08.pdf) for more information. Thanks, June
-
Thnk you June. The datum and ellipse will be the same though right??? D_Moon_2000. This image below is the kind of image I am expecting as the final output when I add the images or put them together as output.

Yes, you got it.

Thank you so much June.... This is exactly what I wanted... So I assume, to near side, i replace 180.0, 0.0 to 0.0, 0.0??? otherwise all the same?

Hi Aravind Bharathvaj, I am not quite sure what kind of help you need. If you are looking for a projection string to be written in the 'map_proj.txt' file in ENVI as talked in the above blog. For the lunar farside orthographic projection centered at 180° longitude and 0° latitude, the projection string is listed below. 14, 1737400.0, 0.0, 180.0, 0., 0., Sample Lunar Orthographic As listed in the top of the 'map_proj.txt' file - 14 represent a ID for Orthographic projection, - 1737400.0 is the radius R for Moon, - the rest of 4 numbers are projection center lat0 and center lon0, and the center (x0, y0) of the projected map - the last is the user defined customized projection name Feel free to contact us if this is not what you want. Thanks, June

Mars Odyssey Release 69 includes new GRS data. The new Raw data (EDR), Derived Neutron Data (DND), and Derived HEND Data (DHD) products cover the period January 1 through March 31, 2019. The new Averaged Neutron Data (AND) and Averaged HEND Data (AHD) products cover the period December 31, 2018 to March 24, 2019, which is Ls=315 to 360 in Odyssey mapping year 09. The data are online at the PDS Geosciences Node at http://pds-geosciences.wustl.edu/missions/odyssey/grs.html.

Dear June, I am trying to make global scale representation of some mineral maps we have processed here in our lab. For that, we need to project the image and represent it in orthographic Near side and orthographic far side. Like the one available in LORC quick map projections. Can you help? Similar projections have been dispayed in many instances of Water discovery, moon mineralogy etc.
