Missing tif files in some LROC CDRNAC products
Susie Slavney replied to Shyam Mohan's topic in For data users
I believe the Matlab function "fread" would be the correct way to read a binary file, although I have no experience with Matlab. You will need to know the size and data type of the .img file, which are given in the corresponding label file (.lbl). In the label, look for the keywords LINES, LINE_SAMPLES, SAMPLE_BITS, and SAMPLE_TYPE. For example, for the product at your link above, the label shows LINES = 52224 LINE_SAMPLES = 5064 SAMPLE_BITS = 16 SAMPLE_TYPE = LSB_INTEGER (this means least significant byte first, or little-endian) The label also tells you that the file has 104449 records, each one 5064 bytes long, and the image data start at the second record. So you'll have to skip the first record. RECORD_BYTES = 5064 FILE_RECORDS = 104449 LABEL_RECORDS = 1 ^IMAGE = 2 I am guessing that the Matlab commands would be something like this: fid = fopen('m1185002263rc.img', 'r'); % Open the file to read status = fseek(fid, 5064, 'bof'); % Skip 5064 bytes from the beginning of the file a = fread(fid, [5064,52224], 'int16' 'ieee-le'); % Read in a 5064x52224 array of little-endian signed 16-bit integers Again, I am only guessing about the Matlab commands based on information I found online here. http://matlab.izmiran.ru/help/techdoc/ref/fread.html The image pixels are stored in the file in order from left to right, top to bottom. I understand the fread statement fills the array in column order. So you might have to transpose the array to get it to display correctly. -
Hi Jairo, Thank you for emailing us with your question. You are receiving the “corrupted file” response because your computer does not have a native application for opening the PDS IMG files. Also, sometimes a cd/dvd image file is called an IMG, so an application used for mounting disk images tries to open the file in a different expected format. A typical PDS image is stored as a simple binary array. It is described by a PDS label (a set of ASCII-text keyword=value statements), which can be either attached or detached. An attached label is embedded at the beginning of the image file; a detached label is in a separate file with the same name, extension LBL. The label tells you everything you need to know to read the image -- the number of lines, number of pixels (samples) per line, the size and data type of a sample, and map projection information if the image is a map. (PDS deliberately does not rely on any commercial or proprietary formats to archive image data, in order to ensure the long-term viability of the data.) Typically IMG files are opened with programs including ENVI, NASA View, or GDAL. ArcMap might support IMG files, but I don’t remember. The IMG files can also be parsed and manipulated with code (Python, IDL, Matlab, C++, C#). In the future, I hope to add functionality into ODE to allow a user to request the files in various formats, but it is not on the near list. In the meantime, GDAL is a standard application for changing formats. http://www.gdal.org/ (general information and the link to download) http://www.gdal.org/gdal_translate.html (basic GDAL commands) Here is an example commands that can be used to convert an img to tif: Gdal_translate -of GTiff D:\test\data\MGN\fmap\fl13s309.img D:\test\data\MGN\fmap\fl13s309.tif NASA View is better for just viewing images: https://pds.nasa.gov/tools/about/pds3-tools/nasa-view.shtml Let us know if you have any further questions. Thanks, Dan

Hi, I downloaded the image files I wanted, but I'm having trouble opening them. The IMG files are supposed to be mounted, but they are always said to be "damaged". Is there a section describing how to deal with all the formats found in ODE? Thank you.

Missing tif files in some LROC CDRNAC products
Shyam Mohan replied to Shyam Mohan's topic in For data users
Thank you Susie for the reply. I am using the data for scientific purpose and hence I prefer to use 'img' instead of 'tif' files which are compressed. Ironically, I read (https://en.wikipedia.org/wiki/TIFF) that 'tif' file format use lossless storage and thus there is no compression. I could locate the 'tif' file corresponding to the product id M1185002263RC in the link that you shared. Initially, I was searching for it in the below link and I could not find it,http://ode.rsl.wustl.edu/moon/productPageAtlas.aspx?product_id=M1185002263RC&product_idGeo=20666502 I am not sure if the below question should be intended in this forum, however I am posting it, How can I read a '.img' file in MATLAB? What is the toolbox or function to read and visualize an 'img' file ? Thank You, Shyam. -
Assigning Map Information to PDS Images in ENVI
Ray Arvidson commented on Jennifer Ward's blog entry in Working with PDS data
M3 operates in different spatial modes depending on the orbit. Would you please supply the actual M3 data set ID that produced different spatial pixels for different wavelengths? That way we can replicated the issue using ENVI's map projection code. Ray Arvidson PDS Geoscience Node Manager -

Gene, The detector temperature requirement for IR delivery to the PDS is < -145.45C. 243D0_07 is higher than that limit. MRO:DETECTOR_TEMPERATURE = -143.586 I will contact you by email to discuss this matter further. Jennifer

Assigning Map Information to PDS Images in ENVI
Shashwat Shukla commented on Jennifer Ward's blog entry in Working with PDS data
Hello, Why do different subset of M3 data gives different spatial resolution while georeferencing through IGM method from ENVI using Lat and Long bands.? Kindly clarify this. -
Hi Jennifer. Thanks for your reply. Has there been any response from them? Thanks again, Gene

Missing tif files in some LROC CDRNAC products
Susie Slavney replied to Shyam Mohan's topic in For data users
Dear Shyam, To answer your questions: 1. The '.tif' files are reduced-resolution, compressed versions of the '.img' files. They are browse images; that is, they are intended to be used for a quick look at the data to help choose products of interest. They are not suitable for science analysis because the data have been compressed. The actual LROC image products are in the '.img' files, and yes, they can be very large. Each '.img' file has an embedded text header at the beginning of the file that has the metadata for the product, including the size, byte order, and bytes per pixel. You could use this information in Matlab to read in the image. 2. I think there should be a .tif file for every .img file. The one for M1185002263RC is online here: http://lroc.sese.asu.edu/data/LRO-L-LROC-3-CDR-V1.0/LROLRC_1023/EXTRAS/BROWSE/2015120/M1185002263RC_pyr.tif For more information about the image products, look here: - Lunar Orbital Data Explorer's User Manual page about LROC http://ode.rsl.wustl.edu/mars/pagehelp/quickstartguide/index.html?lroc.htm - LROC EDR/CDR Software Interface Specification http://lroc.sese.asu.edu/data/LRO-L-LROC-3-CDR-V1.0/LROLRC_1035/DOCUMENT/LROCSIS.PDF You might want to use the Lunaserv Global Explorer and the Quickmap 3D tools on the LROC web site, http://lroc.sese.asu.edu/archive. If you need more help, I will put you in contact with someone at the LROC Data Node. Regards, Susan -
Hello all, Most of the LROC CDRNAC products has both '.img' and '.tif' files. I am assuming that both the files contain images of the same region but the '.img' files have meta data. I have observed that '.img' are typically 300MB and '.tif' files are 30MB in size. I have the following two questions, 1. Why is the '.img' file typically 10 times larger than the '.tif' files ? Is the meta data some huge in size? 2. Some products, for example M1185002263RC does not have a 'tif' file. Is it not available for some products? I am actually creating a mosaic area of 10x10 Km using LROC images of 1.5m/pixel resolution (approx) by stitching them together. I am using MATLAB for this purpose and it can only read '.tif' files. Any help or suggestion would help me in moving forward. Thank You, Shyam.
