  7. 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
  8. Hello June I was studying about the magnetic field and solar wind properties of lunar surface. Can you suggest which data should I go for. Thank you for your time Regards Akash
  9. Thank you June It worked and helped a lot.
  10. Thank you for clearing that up. I notice how the example is the exact measurement in question. Nice job! lol thank you ! JRoberts
  11. The profile plot y -axis is elevation in site frame. To be specific, the elevation values shown are the rover's negative z-axis values because in site frame, the rover's z-axis is positive down. You will notice in the attached example, the elevation of the first point is z = -2.04m in the location list and 2.04m in the profile plot. (Remember, the profile shows elevation as -z values.) If you change the Coordinate frame from Site to Rover using the drop down menu, you will see different z values in the location list. The profile plot x-axis is distance along the profile, with the first point in the plot being the beginning of the profile drawn on the image. This means that, although the plotted elevation is absolute using site frame values, the distance along the profile is relative to the points selected. Note that the profile calculated returns the elevations along a path as if it were "dropped on the ground" between the two points. The profile is not simply the elevation values of the image pixels under the line drawn on the image.
  12. 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.

  13. Works beautifully now. Thank you for the quick response and action. It was working properly within an hour of my post. Nice... I have a question regarding the profile charts and the zero reference. Where the distance along the profile is 0m, the elevation is usually something other than 0m. My measurements normally report something like (0,2.042). My question is: Why is the profile elevation starting reference not the same as the one used for distance along the profile? I'm sure it's simple. Thank you for your help.
  14. Thank you so much June for all the help. Whatever you suggested is workimg and of great help. I just have a last query that how to decide which projection is best for your study. For eg if I want to study the mineral composition around south western part of Moon, whether I should go for Sinusoidal curve or Molleweide or equatorial map projection? Thank you so much once again for your time.
  15. 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.
  16. When I georeferenced the M3 data in either Sinusoidal or Mollweide projection, why isn't the ENVI asking for latitude? Its just asking about longitide and false easting and northing.
  17. Hello. I actually wanted to ask the about the ellipse data representation GCS_Moon_2000, 1737400.0,1737400.0 What does GCS_Moon_2000 represents? The other two repsents the minor and major axes radius of moon
  18. Glad to hear it works for you! June
  19. Hi June, IGM procedure for georeferencing is working now, Thanks a lot, Raj.
  20. 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
  21. Hi Jimmy - thanks for dropping the note. We're sorry for the inconvenience. I tracked down the problem to an integer conversion and the fix is in place. You probably will need to refresh your browser window. Please let me know how it goes.
  22. Hi June, I want to georeference an M3 image (M3G20090205T094623_V01_RFL), I have added Lunar south polar stereographic projection with D_Moon_2000 as datum. As you mentioned I have added the ellipse.txt (GCS_Moon_2000, 1737400.0, 1737400.0), datum.txt (D_Moon_2000, GCS_Moon_2000, 0,0,0) and map_proj.txt (31, 1737400.0, 1737400.0, -90.000000, 0.000000, 0., 0., Moon South Polar Stereographic). But after applying GLT procedure, I am getting georefernced image with no data mostly. Please help me to resolve this issue. Thanks, Raj.
  23. The distance tool works great for me, but I am having issues with the profile tool. Each time I use it, an error is generated "Rats..." and I have to back out of the current image and then re-enter. At that time, I find a profile height has been successfully generated; however, once I try to view the profile, the error is generated again. Is there a known problem going on with this? Thank you... Jimmy R
