    Georeferencing PDS images in ENVI

    Hi Subhabose, The ‘ellipse.txt’ file looks fine to me. In datum.txt, you had an extra ‘,’ in the last line. The correct string would be below. ‘D_Moon_2000, GCS_Moon_2000, 0,0,0’ In file ‘map_proj.txt’, I saw your definition for the Moon North Polar Stereographic projection. Since the maximum and minimum latitude for your data are 59.676 and -1.151 degrees, I would not suggest using the North Polar Stereographic projection.
  5. March 27th, 2018 - More MEX HRSC RDR Version 3 Data Loaded into ODE HRSC new radiometrically calibrated (RDR version 3) image data have been loaded into ODE, with coverage through October 14th, 2016 (Orbit 10-16200). See https://wufs.wustl.edu/ode/odeholdings/Mars_holdings.html

    Georeferencing PDS images in ENVI

    Hi Subhabose, The product ID you gave was not a complete product ID. This value can be found in the product label file. From your ID I cannot tell what type of product you used. Is it the L0 raw data, or the L1B calibrated image, which has 3 versions, either Version1, V2 or V3? Or the L2 reflectance image? Please take a look of below help page. At the bottom of the right panel, 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. http://ode.rsl.wustl.edu/moon/pagehelp/quickstartguide/index.html?isros_chandrayaans_m3.htm Assuming you use the Version3 L1B calibrated image, e.g., ' M3G20081229T022350_V03_RDN', you can access the location and geometry information in the *.LOC and *.OBS files and relate it to the spectra of the *.RDN files using ENVI as documented in the file 'M3 ENVI User's Guide'. And you can use GLT in ENVI to do the georeference. As for your question about map projection, from your screen copies, I can only tell the Datum you used are not correct. Because WGS-84 is used for Earth. If you can send me the strings that you have updated in three files datum.txt, ellipse.txt, map_proj.txt, I can dig more into your issues. Thanks, June

    Assigning Map Information to PDS Images in ENVI

    Hi Tarun, I just noticed that you are using the Mini-RF MAPCDR data product. And this product has an Oblique Cylindrical projection. I doubt if ENVI can handle the Oblique Cylindrical projection. USGS ISIS3 support the Oblique Cylindrical projection. You can use ISIS's cam2map or map2map functions to reproject the MAPCDR data to other projections, before you further process the data in other GIS software. More information about USGS ISIS tools could be found in the below link. thanks, https://isis.astrogeology.usgs.gov/ June

    Assigning Map Information to PDS Images in ENVI

    Hi Tarun, It looks to me you didn't edit the 'ellipse.txt'file as mentioned in the previous post. I have copied the steps below for your reference. Feel free to let me know if you still have problems. Thanks, June 1. Update the map projection files - ENVI includes three map projection files related to the definition of datum, ellipse and map projections. First check where ENVI points to the map projection files. - Select File > Preference, under User Defined Files Tab, find Map Projection File. - If the right blank is empty, ENVI will point to the map projection files saved under the default system folder where ENVI was first installed, e.g.,"C:\Program Files\Exelis\ENVI50\classic\map_proj\" for ENVI 5.0 classic. This path may vary machine by machine. Otherwise, ENVI will point to the map projection files saved in the path as defined in the right blank. - Go to the folder where ENVI points to the map projection files. Backup the three files: "datum.txt", "ellipse.txt", and "map_proj.txt" before you make any changes. - Update file datum.txt - Open datum.txt - Add string "D_Moon_2000, GCS_Moon_2000, 0, 0, 0" to the end of the file - Save (If you have permission problem to save the file, please copy the file out to another folder. After changing, copy the saved file back to the original folder. If the permission is still denied, please let your system administrator to update the files.) - Update file ellipse.txt - Open ellipse.txt - Add string "GCS_Moon_2000, 1737400.0, 1737400.0" to the end of the file - Save (take care of the permission problem as above) - Update file map_proj.txt - Open map_proj.txt - Add string "31, 1737400.0, 1737400.0, 90.000000, 0.000000, 0., 0., Moon North Polar Stereographic" to the end of the file [This string needs to be changed to the actual projection you needed for your data) - Save (take care of the permission problem as above) - Restarting ENVI will update the changes in the map projections.
  14. February 9, 2018 – MRO HiRISE Updates - MRO HiRISE EDR, RDR, DTM and Anaglyph data products released through January 1, 2018 (Orbit 53,599) See https://wufs.wustl.edu/ode/odeholdings/Mars_holdings.html

    Why is there a flip in LROC Images?

    Hi Shyam Mohan, Both the LROC *.img data and browse images in Lunar ODE are the original data provided by the LROC team. There is nothing wrong with the data products you downloaded from ODE. It is the way how to interpret the image and the index tables. Please refer to the index.tab and index.lbl in the below link. http://lroc.sese.asu.edu/data/LRO-L-LROC-3-CDR-V1.0/LROLRC_1013/INDEX/ In index.lbl, you will find below definitions for the columns 70 to 79 for the lat &lon coordinates of the center point and 4 corner points of the image. And you can find corresponding index records from index.tab for the data product M1106080949LC. If you fill those numbers for those 4 image corners, you will see the coordinates are correct and consistent with the LROC quickmap. OBJECT = COLUMN NAME = CENTER_LATITUDE COLUMN_NUMBER = 70 DATA_TYPE = ASCII_REAL START_BYTE = 798 BYTES = 6 FORMAT = "F6.2" NOT_APPLICABLE_CONSTANT = 999.99 DESCRIPTION = "The planetocentric latitude coordinate at the center of the observation." END_OBJECT = COLUMN OBJECT = COLUMN NAME = CENTER_LONGITUDE COLUMN_NUMBER = 71 DATA_TYPE = ASCII_REAL START_BYTE = 805 BYTES = 6 FORMAT = "F6.2" NOT_APPLICABLE_CONSTANT = 999.99 DESCRIPTION = "The planetocentric longitude coordinate at the center of the observation." END_OBJECT = COLUMN OBJECT = COLUMN NAME = UPPER_RIGHT_LATITUDE COLUMN_NUMBER = 72 DATA_TYPE = ASCII_REAL START_BYTE = 812 BYTES = 6 FORMAT = "F6.2" NOT_APPLICABLE_CONSTANT = 999.99 DESCRIPTION = "Upper right latitude." END_OBJECT = COLUMN OBJECT = COLUMN NAME = UPPER_RIGHT_LONGITUDE COLUMN_NUMBER = 73 DATA_TYPE = ASCII_REAL START_BYTE = 819 BYTES = 6 FORMAT = "F6.2" NOT_APPLICABLE_CONSTANT = 999.99 DESCRIPTION = "Upper right longitude." END_OBJECT = COLUMN OBJECT = COLUMN NAME = LOWER_RIGHT_LATITUDE COLUMN_NUMBER = 74 DATA_TYPE = ASCII_REAL START_BYTE = 826 BYTES = 6 FORMAT = "F6.2" NOT_APPLICABLE_CONSTANT = 999.99 DESCRIPTION = "Lower right latitude." END_OBJECT = COLUMN OBJECT = COLUMN NAME = LOWER_RIGHT_LONGITUDE COLUMN_NUMBER = 75 DATA_TYPE = ASCII_REAL START_BYTE = 833 BYTES = 6 FORMAT = "F6.2" NOT_APPLICABLE_CONSTANT = 999.99 DESCRIPTION = "lower right longitude." END_OBJECT = COLUMN OBJECT = COLUMN NAME = LOWER_LEFT_LATITUDE COLUMN_NUMBER = 76 DATA_TYPE = ASCII_REAL START_BYTE = 840 BYTES = 6 FORMAT = "F6.2" NOT_APPLICABLE_CONSTANT = 999.99 DESCRIPTION = "lower left latitude." END_OBJECT = COLUMN OBJECT = COLUMN NAME = LOWER_LEFT_LONGITUDE COLUMN_NUMBER = 77 DATA_TYPE = ASCII_REAL START_BYTE = 847 BYTES = 6 FORMAT = "F6.2" NOT_APPLICABLE_CONSTANT = 999.99 DESCRIPTION = "lower left longitude." END_OBJECT = COLUMN OBJECT = COLUMN NAME = UPPER_LEFT_LATITUDE COLUMN_NUMBER = 78 DATA_TYPE = ASCII_REAL START_BYTE = 854 BYTES = 6 FORMAT = "F6.2" NOT_APPLICABLE_CONSTANT = 999.99 DESCRIPTION = "Upper left latitude." END_OBJECT = COLUMN OBJECT = COLUMN NAME = UPPER_LEFT_LONGITUDE COLUMN_NUMBER = 79 DATA_TYPE = ASCII_REAL START_BYTE = 861 BYTES = 6 FORMAT = "F6.2" NOT_APPLICABLE_CONSTANT = 999.99 DESCRIPTION = "Upper left longitude." END_OBJECT = COLUMN The reality is the left and right of an image is not always the west and east of real direction as you noticed, and north of image will not always be the straight up direction. It totally depends on the flight direction of the satellite and the cameras onboard the satellite. That is why you will always need to look at the index table to find the corner coordinates of the LROC data to further interpret the images. Please let me know if you still have any questions about the LROC data set. Thanks, June

    DIVINER

    Each Diviner RDR data product consists of two files. They are a detached PDS label and an ASCII data table file. You can open the ASCII data table directly with UltraEdit, Excel or other tools. For more information about Diviner RDR products, please see the RDR and Derived Product Software Interface Specification file @ http://pds-geosciences.wustl.edu/lro/lro-l-dlre-4-rdr-v1/lrodlr_1001/document/dp_sis.pdf . Our lunar ODE provides the DIVINER RDR Query Tool (http://ode.rsl.wustl.edu/moon/indextools.aspx?displaypage=lrodiviner) to select RDR data from the products by area. The tool returns data in a variety of formats including an ASCII table, Shapefile, and Binned Images. In addition to the RDR products, DIVINER offers a set of gridded data products (GDRs). The GDR products are RDR products assembled into global grids, with various resolution and channel combinations. I am wondering the DIVINER GDR products might meet your needs. Please see below help page for more information and let me know if you have more questions. Thanks, http://ode.rsl.wustl.edu/moon/pagehelp/quickstartguide/index.html?diviner.htm
