    Note:
    - The release of Diviner RDR products has been delayed in order to correct a data processing error recently discovered. See errata.txt on the Diviner RDR volume for details.
    - Additional LROC volumes have been re-released by the LROC team to update the data quality id to reflect 2 mask columns being excluded from image statistics. The additional re-loaded volumes in ODE are 39C, 40A, 40B, 41A, 42A, 42B, 42C, 43A, 43B, 43C, and 44A for EDRs and CDRs. See ERRATA.TXT under each volume for more information.

     

  3. Hi Neha Panwar,
    Please visit the post below, which gave steps on how to define a datum in ENVI. After you change the datum from WGS 84 to D_Moon, It might solve your issue of offset. Feel free to post a screen copy of your result if you still have problems or any questions. Thanks,

  9. There is a long list of discussion on the reading of the LP NS special data products in binary format at openplanetary.slack.com (https://openplanetary.slack.com/archives/C3RHA4HFX/p1636384638008600)
    The description of the binary *.dat data is copied below (https://pds-geosciences.wustl.edu/missions/lunarp/reduced_special.html). Basically, they are binary image arrays as 2-byte MSB_INTEGER, 720 samples * 360 lines.
    "Each binary file is formatted as an image covering the entire planet with an array of 720 samples and 360 lines. Data values are scaled as integers in the image array with two bytes per pixel in IEEE order. For all binary files except the potassium, radon, and polonium, image values are ten times the values given in the ASCII files. The binary files for potassium abundances have integer values that are the same as values given in the corresponding ASCII file. The binary files for the radon and polonium data have integer values that are 1000 times the values given in the corresponding ASCII file. The binary image is a simple cylindrical map projection with 0.5° pixel size. The first image line corresponds to the south pole and the last image line corresponds to the north pole of the moon. The first sample corresponds to -180° East longitude and the last sample corresponds to 180° East longitude. Binary file names have the form <name>.dat and are about 0.5 MB in size."

    Some sample Python codes to read the binary data are copied below.
    From Chance,

    import numpy as np
    import struct
    import matplotlib.pyplot as plt
    
    pds_lp_file = './thoriumhd.dat'
    pds_lp_data_binread = []
    with open(pds_lp_file, 'rb') as file:
        file.seek(0,2)
        num_bytes = file.tell()
        file.seek(0)
        i = 0 
        while i < num_bytes:
            binary_data = file.read(2) 
            i += 2 
            unpacked = struct.unpack("h", binary_data) 
            pds_lp_data_binread.append(tuple(unpacked)[0])
            
    magic_num = 720
    
    pds_lp_arr = np.array(pds_lp_data_binread).reshape((int(len(pds_lp_data_binread)/magic_num), magic_num))
    print("Data shape: {}".format(pds_lp_arr.shape))
    print("Data min: {}".format(np.amin(pds_lp_arr)))
    print("Data max: {}".format(np.amax(pds_lp_arr)))
    
    
    plt.figure(figsize=(6,6))
    plt.imshow(pds_lp_arr)
    plt.show()

    From Mario D'Amore, please see more details at https://gist.github.com/kidpixo/549fd1c95956166855431cc81e141626

    import numpy as np
    import pandas as pd
    import matplotlib
    from matplotlib import pyplot as plt
    %matplotlib inline
    
    # read using numpy
    data = (np.fromfile('therms.dat',dtype=np.dtype('>h'),)/10)
    # 10 scaling  is from the documentation, changes for each file.
    # 360,720 is from the documentation, changes for each file.
    plt.figure(figsize=[8,3.5])
    plt.imshow(data.reshape([360,720]),origin='lower',cmap=plt.cm.inferno_r)
    plt.colorbar(fraction=0.025)
    plt.title('therms with numpy')
    
    # read using pandas
    df = pd.read_csv('therms.txt',skiprows=12,sep=',',
                names=['Lat_min','Lat_max',
                       'Lon_min','Lon_max',
                       'Counts' ,'Std'     ]
                    )
    df.plot.scatter(x='Lon_min',y='Lat_min',c='Counts',
                    cmap=plt.cm.inferno_r,figsize=[8,4],
                   title='therms with pandas')

    But one thing need to notice is that all the binary data values are scaled to integers. After reading the data and scaling back to its original value, you will find there is slightly difference in the the accuracy of decimal points between ASCII and binary for all the data products if they have non-integer values in the ASCII files initially. For example,

    ASCII Data                                Min                         Max
    thoriumhd.txt                            0.32075                12.935
    hydrogenhd.txt                      -56.197                  195.55
    ironhd.txt                                   2.6220                 26.645

    Binary Data                 Min      Min/10       Max     Max/10
    thoriumhd.dat                 3         0.3           129       12.9
    hydrogenhd.dat          -561    -56.1           1955    195.5
    ironhd.dat                       26        2.6          266       26.6

     

     

  10. November 8, 2021 – MRO HiRISE Updates
    - MRO HiRISE EDR, RDR, DTM and Anaglyph data products released through September 25, 2021 (Orbit 71099)

  11. A user want to use the LP NS special data products for hydrogen abundance at ~15 km/pixel for his research. He want to import it into ArcGIS Pro and run a tool to show only data point with hydrogen signatures > 100ppm since water-ice should be present close to the surface.

    The link to the archived LPNS data: https://pds-geosciences.wustl.edu/missions/lunarp/reduced_special.html

    Below is the steps to access the data and do the conversion from an ASCII to a Geotiff in ArcGIS
    1)    Choose the data.
    The radius of the Moon is about 1737 km, which means the Moon scale is about 30 km/deg at the equator.
    scale = radius *2 *pi / 360
         So for gridded data at 1/2 deg corresponds to about 15 km/pix.
    2)    Convert from an ASCII to a Geotiff in ArcGIS Pro. ‘ASCII To Raster’ is a deprecated tool in the ArcGIS Pro. The Copy Raster tool can be used in the ArcGIS Pro to convert an ASCII file representing raster data to a raster dataset. First prepare an ASCII file for ArcGIS Pro according to the information in https://pro.arcgis.com/en/pro-app/latest/tool-reference/conversion/ascii-to-raster.htm. See attached example ASCII files. Suggest to change the file extension to *.asc to get better performance in ArcGIS Pro. Other extensions might have problem in the conversion. Then run the Copy Raster tool to make the conversion.
