  9. Did you try to use ENVI mask or band calculation to filter out the black pixels? If you like, you can upload the CRISM output together with the ENVI header online. I can have a try of your data. Thanks, June
  10. Do you mean the black pixels along the edge of the image, which represent no data? If that is the "black pixels" you want to clean, in ArcGIS, when you overlain the CRISM output onto a DTM, right click the image, and choose properties. Below is the instruction to remove the background area of a raster layer using the Unique Values renderer in ArcMap. Arcscene has similar function to set the background color as transparent. Or you can google an example. I cannot use ArcGIS desktop these days due to a university license issue. People are still working on that. If you still have problem, I can send you a pic example as soon as I can access my ArcGIS desktop again. Thanks, https://desktop.arcgis.com/en/arcmap/10.3/manage-data/raster-and-images/removing-the-background-using-the-unique-values-renderer.htm June
  11. I am not quite understand your question. Do you like to know how to give a 3D view? I saw your overlain of the CRISM onto a CTX. If you overlain all the images onto a DTM, and change the terrain exaggeration factors, you will see something like above figures from different points of views. HiRiSE DTM has much higher resolution than the DTMs from HRSC and MOLA. Map resolution for a HiRISE image is about 25cm/pixel, and the HiRISE DTM is about 1m/pixel. HRSC DTMs have various resolution from 50m/pixel to 400m/pixel. Most of the products are at the resolution of ~50m/pixel, 75m/pixel, and 100m/pixel. MOLA DTM is about 500m/pixel. CTX image is about 6m/pixel. And FRT CRISM data are about 18m/pixel. Depending on your needs, the higher resolution of a DTM, the more detailed features the terrain can represent.
  12. January 6th, 2020 - Mars Odyssey Release 70 Data Updates Loaded NS and HEND raw and derived data (EDR, DHD, DND, AHD, and AND) into ODE through June 30th, 2019 Updated THEMIS standard data products (IREDR, IRRDR, IRBTR, VISEDR, VISRDR and VISABR data) from February 19th, 2002 to June 4th, 2019 Updated THEMIS geometry data products (IRGEO2, IRPBT2, VGEO2, and VISALB data) from September 28th, 2013 to June 4th, 2019 See https://wufs.wustl.edu/ode/odeholdings/Mars_holdings.html.
  13. Hi Wladimir , ENVI 5.3 would also work for you. Please have a try. You can search for CTX EDR and Non-PDS Compliant RDRs through Mars ODE (https://ode.rsl.wustl.edu/mars/indexProductSearch.aspx) as shown in the attached fig1. In the data search results page (fig2), you can download the 'Pyramidized GeoTIFF' under 'Processed CTX' panel on the right. The Pyramidized GeoTIFF image has spatial reference information included in the image header. You can export a map projected CRISM image using the CAT menu function as shown in the fig3. The CRISM output can be overlain with the CTX RDR in ArcGIS. Please let me know if this doesn't work for you. Thanks, June Fig1 Fig2 Fig3
  14. Hi Wladimir , You can download non-PDS Compliant CTX RDR data from Mars ODE(https://ode.rsl.wustl.edu/mars/indexProductSearch.aspx) or from ASU Mars Space Flight Facility's Mars Image Explorer (http://viewer.mars.asu.edu/planetview/inst/ctx/#T=0) directly. Those CTX RDR data are map projected and could be overlain with the HiRISE DTM. ArcGIS can project the data on the fly if they have different projections. I can also help if you need more assists on data registration. Thanks, June

  18. Hi Akash, PDS Geosciences node archives the Lunar Prospector MAG/ER raw data, basically the downlinked telemetry format, available at https://pds-geosciences.wustl.edu/missions/lunarp/index.htm. You can find more calibrated and derived MAG data from the PDS PPI node, https://pds-ppi.igpp.ucla.edu/mission/Lunar%20Prospector/LP/MAG#. This link describes the magnetometer experiment at PPI and provides links to the data sets that they have. Most of the raw, calibrated and derived MAG data can be searched and downloaded from the Lunar ODE web, https://ode.rsl.wustl.edu/moon/indexProductSearch.aspx. Please see below attached example data product search page, and let us know if you have any problem to access the data. Thanks, June
  19. That is a very good question but hard to answer. When choosing a projection, you need to consider about how you would like to use the map and what your research interest is. No map is error free. Do you like to preserve the shape, or preserve the area, or preserve the scale, or the direction, or something else? If you want to study the mineral composition on the moon. E.g., you want to know the certain coverage of a mineral, if areas are not in true proportion, the map will give false interpolation of the data. So choosing equal-area projections will better fit this need. The size of any area on an equal-area projection map is in true proportion to its size on the moon. The decision also depends on the location of the area to be mapped. Is it a polar, mid-latitude, or equatorial region? A reasonable projection can minimize the distortion for your area of interest. Sinusoidal and Molleweide projections are both a pseudocylindrical equal-area projection. Sinusoidal projection represents the poles as points. There is no distortion at the equator and the prime meridian, but the distortion gets worse the further away from either. Scale is constant along the central meridian and all parallels. Molleweide projection represents the equator as a straight horizontal line perpendicular to a central meridian one-half its length. The 90th meridians are circular arcs and all other meridians are equally spaced elliptical arcs. The parallels are unequally spaced straight lines parallel to each other. Poles are points. Scale is true along latitudes 40°44' N and S. Distortion increases with distance from these lines and becomes severe at the edges of the projection. Equal-area is preserved for this projection but at the expense of shape distortion. Shape is not distorted at the intersection of the central meridian and latitudes 40°44' N and S. Distortion increases outward from these points and becomes severe at the edges of the projection. You may notice Simple Cylindrical, or Equirectangular, or Equidistant Cylindrical projection are used in many planetary maps. This projection is very simple to construct and it converts a globe into a Cartesian grid. When the equator is used as the standard parallel, the grid cells are perfect squares, but if any other parallel is used, the grids are rectangular. The scale is correct along the meridians and the standard parallels for this projection. Distortion increases as the distance from the standard parallels increases. The poles are represented as straight lines across the top and bottom of the map. When read below book, you can get more pros and cons for different maps projections and make your own decision. Thanks, June Snyder, John P., 1987, Map Projections, A Working Manual, U.S. Geological Survey Professional Paper 1395, 385p. http://pubs.er.usgs.gov/publication/pp1395
  20. Hi Akash, no need of central_latitude for both projections. GCS_MOON_2000 is a geographic coordinate system, whose datum is the D_Moon_2000 in GIS software. The other two are major axis and minor axis in meters. Please read 'LRO Project and LGCWG White Paper' at https://lunar.gsfc.nasa.gov/library/LunCoordWhitePaper-10-08.pdf for more information.
  21. Glad to hear it works for you! June
  22. Hi Raj, Have you tried the docs at http://ode.rsl.wustl.edu/moon/pagehelp/quickstartguide/index.html?isros_chandrayaans_m3.htm? At the bottom of the page, 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. I also attached below another instruction with other example data other than yours. Please try with your own data and let me know if it works for you. Thanks, June Instruction to work with M3 level2 data.pdf
