  1. Release 54 from the Mars Reconnaissance Orbiter mission includes new data for CRISM, SHARAD, and Gravity/Radio Science. The data are online at https://pds-geosciences.wustl.edu/missions/mro.
  2. We are pleased to announce that the USGS Unified Geologic Map of the Moon is now available through the Lunar ODE map search. The map is displayed as two map layers in ODE. 1. The first layer contains unit contacts, geologic unit polygons, linear features, and unit and feature nomenclature annotation. 2. The second layer, which we call the base layer is a shaded-relief product derived from SELENE Kaguya terrain camera stereo (equatorial, ~60 m/pix) and LOLA altimetry (north and south polar, 100 m/pix).
  3. We have released a new version of our MakeLabels tool. The new 6.2 version includes additional features to help with the creation of PDS labels. The program and documentation can be found on the PDS Geosciences Node's MakeLabels page. Version 6.2 updates include: The output label destination directory is created, if it does not already exist and the user has appropriate permissions. Any template label tags that are not replaced (due to syntax errors or missing columns in the spreadsheet) are listed in the post-processing summary report. The MakeLabel's GUI interface now has a sizeable report window. The report summary has been moved to the end of the processing output report. The option to upper or lower case fields from the source spreadsheet has been added to the template tags. A new template tag allows a single line to be hidden if it's corresponding field is empty in the spreadsheet. (example: <name><!-- |specimen_id| OR HIDE-THIS-LINE --></name>) Show if and hide if template tags no longer need to be left aligned in the template. These tags can be indented and spaced with the surrounding XML.
  4. We are pleased to announce the release of the PDS Geosciences Node Spectral Library website. See the release announcement under the main forum announcements. Feel free to ask questions and provide feature requests on this forum. Thanks!
  5. We are pleased to announce the release of the new PDS Geosciences Node Spectral Library website. The PDS Geosciences Node Spectral Library is a database of laboratory spectra submitted by various data providers. It currently includes spectra from the Reflectance Experiment Laboratory (RELAB) at Brown University. Additional data sets will be added to the website in the coming months. The website allows users to search the catalog of specimen and measurements using a facet search. Results can be viewed in quick view summary or full detail pages. Measurement data can be downloaded individually or through a cart system.
  6. Hi Christy, I just tried the Windows version of the software on my Windows 10 machine. It would not run properly, either. I think we can assume the software has not kept up with the latest operating systems. I do have a couple of alternative options. I have confirmed that the files can be viewed with the PDS4 viewer: https://sbnwiki.astro.umd.edu/wiki/PDS4_Viewer Using this tool, the data files can be exported as csv, tab delimited, and additional formats. Keep in mind that the archive you mentioned is both PDS3 and PD4 compatible. To use PDS3 tools, use the .lbl label, while PDS4 tools will use the .xml label. The XML label will be needed for the PDS4 Viewer. You could also write a script with IDL, MATLAB, Python, or another programming language to parse the data files. The column specifications are found in the label files. The PDS3 label file refers to format files which are found in the archive's label directory (https://pds-geosciences.wustl.edu/messenger/mess-e_v_h-grns-3-grs-cdr-v1/messgrs_2001/label/). The product you mentioned refers to https://pds-geosciences.wustl.edu/messenger/mess-e_v_h-grns-3-grs-cdr-v1/messgrs_2001/label/grs_cal_sh3.fmt. The PDS4 label contains all of the column definitions. Let me know if you have additional questions. Best wishes, Dan
  7. Hi There, I am one of the developers who maintains the ODE website. I ran the same query in the ODE LOLA RDR Query tool, and I received the same response. I believe it is reasonable. Remember, you are just limiting the output to one day. The tool is not setup very well for global coverage searches, but it can be done for narrow time windows. If you wish to query 2014-2019, I would suggest doing a region of interest. That is more of the objective of the query tool. The limited areas of coverage for 2014 and later is expected. The orbiter was in a different orbit and the instrument issues you mentioned. To see the different in coverage for later years, you can use the ODE map search page to filter LRO LOLA RDR coverage to specific time ranges. Link to map search interface: https://ode.rsl.wustl.edu/moon/indexMapSearch.aspx Map interface limited to LOLA RDR (image mapSearch1.jpg) LOLA RDR filtered to 2014 observations.

  8. The ODE map search has been updated to have product coverage map layers grouped by mission/instrument/processing level. This map layer organization matches the product search page. Mars Orbital Data Explorer Map Search Lunar Orbital Data Explorer Map Search Mercury Orbital Data Explorer Map Search Venus Orbital Data Explorer Map Search Mars ODE Map Search Example:
  9. The PDS Geosciences Node and the LROC Data Node have established a faster data transfer method. As a result, ODE cart downloads of LROC data will be fulfilled noticeably faster than in the past. We encourage users to give it a try through the Lunar ODE website.
  10. New functionality has been added to the ODE product search page to allow users to select a freehand polygon location for coverage searches. Similar freehand polygon search filtering has been added to the map search page.
  11. Hi Raj Patel, Thank you for contacting us about your question. First, I confirmed there are no .QUB files in the THEMIS IRBTR (Infrared Brightness Temperature Record) data set. Newer versions of GDAL support the conversion of a .QUB file type into GeoTiff (.tif). Here is an example of the command: Gdal_translate -of GTiff D:\test\data\I00818001RDR.QUB D:\test\data\I00818001RDR.tif The first link on the following FAQ describes the tools ASU's Mars Space Flight Facility recommends for opening THEMIS images. http://viewer.mars.asu.edu/faq#t6n18 Let me know if you have further questions. Best wishes, Dan
  12. Hi Deepak, Thank you for the valuable suggestions and feedback. Our staff will be discussing these suggestions over the next couple of weeks to determine our current capabilities and prioritizing future ODE updates. I will be able to provide you with more details after these discussions occur. Also, we will have a booth at LPSC where your presentation ideas can be discussed. Please stop by the PDS booth during LPSC. Best wishes, Dan
  13. 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
