  1. 2022-0418-AN-MSL-Navcam-order.mp4 The above video demonstrates how to order data from the Analyst's Notebook using search filters and the cart order system. The transcript of the video is provided below.
  2. Data and documentation from Mars InSight lander acquired through 31 December 2021 are released. Some data may still be loading into the Notebook; see Data release status for details. Some instrument teams may include additional and/or reprocessed data in their archive deliveries to PDS. Refer to instrument errata and readme documents for details, or contact us with questions. https://an.rsl.wustl.edu/ins
  3. Data and documentation from Mars 2020 Perseverance rover sols 180 to 299 are released. Some data may still be loading; see Data release status for details. Some instrument teams may include additional and/or reprocessed data in their archive deliveries to PDS. Refer to instrument errata and readme documents for details, or contact us with questions. https://an.rsl.wustl.edu/m20
  4. Data and documentation from MSL Curiosity rover sols 3193 tp 3289 are released. Some data may still be processing. See Data release status for details. Some instrument teams may include additional and/or reprocessed data in their archive deliveries to PDS. Refer to instrument errata and readme documents for details, or contact us with questions. https://an.rsl.wustl.edu/msl
  5. The Notebook is the only resource for these documents. You might find similar sites with mission logs hosted by various instrument teams.
  6. Great question. The sol documents you refer to are the Mission Manager and Documentarian reports that provide a view into science operations—insight into why and how particular observations were made. The reports have not been edited except for grammar and spelling, and to remove spacecraft and instrument sensitive materials. As you note, the sol documents are not part of the formal science archive. They are provided courtesy of the respective mission science teams who approve the content. Separate from the sol documents are mission and data set documents that are collected from archive bundles and volumes and are designed to promote understanding off the mission, spacecraft, instruments, and data formats. I have updated the online help to include a more detailed description of sol documents, highlighting the fact that they are not part of the formal archive.
  7. Data and documentation from MSL Curiosity rover sols 3069 to 3192 are released. Some data may still be processing. See Data release status for details. Some instrument teams may include additional and/or reprocessed data in their archive deliveries to PDS. Refer to instrument errata and readme documents for details, or contact us with questions. https://an.rsl.wustl.edu/msl
  8. The Image viewer tool has an updated drawing library. Users should notice improvement in text annotation quality and general responsiveness. See Image viewer for more about the tool.
  9. The Mars 2020 Analyst's Notebook for Perseverance Rover is released in beta version and is available to the public. The Notebook includes data and documentation from PDS releases 1 and 2, containing data from sols 0 to 179. https://an.rsl.wustl.edu/m20 Known limitations for the beta version are described in the online help.
  10. Hi Neal - Your question makes perfect sense. In the data search, you can enter a sequence ID as a search criterion. The available sequences will appear as you type, so by entering "15298", for example, the selection box provides the correct sequence ID "mcam15298". Search results will appear on the right side where you can add the found items to your cart from the menu. See the attached image as an example. You can apply other search criteria as you wish. The default results for MastCam will be DRCX products. If you are looking for XXXX products, try this trick: select "All products" from the "Results view" option at the top of the filter list, and then enter "*XXXX" in the "ID" option at the bottom of the filters. You can further restrict the selection to omit thumbnails by selecting "C" Mastcam data type under the "Type" filter option. Tom
  11. The Analyst's Notebook has been updated with data from release 5, containing data from sols 391 to 478 for the InSight lander. https://an.rsl.wustl.edu/ins
  12. Hi, Jimmy. You should be able to delete individual measurements and other elements by clicking on the corresponding trash can icon in the list of elements to the left of the image. See the image below for an example. Note that deleting one annotation may delete others as well. For example, if you delete a location that is the endpoint of a distance measurement, the endpoint locations and the distance measurement all will be deleted. You will receive a warning in such cases asking you to confirm the delete. Please let us know if you still feel that the tool isn't working the way you expect. I am glad that you find the measurement tools useful. You are welcome to make suggestions for tool enhancements.
  13. Hi Dane - You are correct...the Analyst's Notebook has changed a lot over the past 8 years. The procedure is largely the same, although the resulting image is downloaded rather than popped open, as you say. It is important to note that the RGB is created using a simple algorithm that performs a 2% linear stretch on the source images and then assigns them to the red, green, and blue channels to make the composite image. Ideally, one would want to perform custom stretches on radiometrically calibrated source images using image processing software such as ENVI. The scene content affects the Notebook's default linear stretch and thus how the simple RGB looks. What is the image you are working with? And how important is it to you to have the custom image pop up in a browser tab vs direct download?
  14. 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.
  15. 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.
  16. You are correct, Jimmy. The Mastcam L/R have different fields of view which can make working with the stereo pairs more difficult. The Notebook uses Navcam XYZ data products generated by the team to support the measurement and distance tools. However, the Mastcam team does not produce XYZ data products, thus the Notebook measurement tools can't support Mastcam images taken as stereo pairs.
  17. You can use GDAL to convert the IMG file to a number of formats. I used v2.4. Be sure to use the PDS label (.LBL) file as the input to gdal_translate: gdal_translate -of GTiff 1627MR0083990000801607K00_DRCX.LBL .\1627MR0083990000801607K00_DRCX.tif GDAL is available at http://www.gdal.org/ and you can read more about the gdal_translate command at http://www.gdal.org/gdal_translate.html
  18. You can find the raw image archives at the PDS Cartography and Imaging Sciences Node: https://pds-imaging.jpl.nasa.gov/volumes/msl.html
  19. The sol 1627 sequence does have 112 thumbnail video frames (product type "K"). Unfortunately, the command sequence did not include a request for full-resolution frames to match. Note that the 10 K-type products you see for sol 1627 are really the two "XXXX" images and the eight derived images (four from each) that include a variety of color correction, linearization, and other techniques applied. The four Mastcam derived image types (also called processing codes) are DRXX, DRCV, DRLX, and DRCL. You can read about them in the data product SIS (Software Interface Specification). In the Notebook, click on the Resource tab, then choose "View documents". Select Mastcam and scroll down to the document titled "MSL_MMM_EDR_RDR_DPSIS.PDF". Only a handful of sols have full-resolution (or higher-resolution) Mastcam movie sequences. Through the current data release, the sols are: Type K, sols 351, 363, 368, 713, 1032, 1627, 1668, 1692, 1693, 1972 Type L, sols 363, 368, 369, 650, 713, 1032 Type M, sols 284, 284, 289, 351, 1625 The K-type sequences generally have the fewest frames per sequence. Some sols have multiple sequences. You can find the images in the Notebook from the Search > Data form. Enter the sol, instrument, and product type, and also put the processing code "DRCX" in the Product ID box. This will restrict the number of images that are returned. PS. Nice video. I'd like to see what you get from higher-res images.
  20. Glad to hear the tutorial helped. Although not trivial, you can use the Mastcam SIS (Software Interface Specification) in conjunction with individual product labels to work out the pointing information. The scale is a bit tougher. We are working on adding image footprints to the traverse map to show orientation. We will also consider adding pointing information to the product overview page to at least provide basic information about where the image is relative to the rover. The Mastcam SIS is available here: http://an.rsl.wustl.edu/su/t8F4Tcw3 Note that this link may change as documents are updated. I found the document from the Resources tab under "Mission and instrument data set documents" and then choosing "Mastcam".
  21. Hi there. If you are looking at a Hazcam or Navcam image that is part of a stereo pair, you can use the Notebook's Image Viewer. There are measurement tools built in to let you obtain locations and distances and to view elevation profiles.The tool is a little hard to find--we recently started work on some tutorials to help users like yourself find these tools and learn how to use them, but they still are in production. In the meantime, let me briefly walk you through getting to and using the Image Viewer measurement tools. To get started in this example (a Navcam stereo pair from sol 1292), click on this link: http://an.rsl.wustl.edu/su/y6Y8N Side note, explanation of how I got to this page in the Notebook: Open the Analyst's Notebook for MSL and go to the Sol Summaries (the orange "sun" icon). This shows the data, documents, etc for each sol. If you click on a sol to expand it, you then have an option to expand the Data Products list for that sol. Clicking on any product in the list brings up a window about that product or group of products. Your screen should look something like screen shot 1. On the left is the sol summary list, and on the right is a Navcam stereo pair (and the resulting anaglyph image). We will work with the left image. The shortest was to get to the Image Viewer for that image is to click on the menu button where the red arrow is pointing in screen shot 1. A menu should open and your screen should look like screen shot 2. Now click on the Image Viewer link (in the red box in the screen shot 2). You should now see something like screen shot 3. Depending on your screen size, the Image Viewer space may be pretty small. You can get more area to work with by clicking on the two buttons highlighted in screen shot 3. In the Image Viewer, there is a left side with some controls, and the right side with the image. At the start, you are assigned the Pointer tool. Switch to the Distance Tool by clicking on the ruler icon highlighted in screen shot 4. A few things will happen. 1. The Distance tool icon will be highlighted in yellow to show it is selected. 2. Directions will appear (circled in red on screen shot 4) to show how to use the tool. 3. A purple overlay mask will appear to show where there are XYZ data in the image (purple is out of bounds). In this example I will create a distance using by following the instructions above the image: left click at the starting point, left click again where I want it to end, and then click the Complete button in the instructions. My screen looks like screen shot 5. There is an entry in the Distance table on the left. When I click on that like (in the red box in screen shot 5), the I have the opportunity to change the settings. I chose to increase the label size so it would be a little bigger. Note that you can export the image by selecting File > Download annotated image in the Image Viewer menu. Also, if you sign in with an account, your measurements will be saved and are loaded automatically the next time you open the image in the Image Viewer, even on another computer. There is additional Image Viewer help at this Notebook help page.
  22. Hi Brennan - Great questions. The easy one first. There are a couple of ways to access the SIS documents. From the product page (if you are looking at a specific Pancam image, for example), you can click on the blue help icon in the menu bar and select "All Pancam archive documents". That will get you a potentially overwhelming list of all sorts of documents from the archive volumes, such as calibration reports. As noted at the top of the list, the SIS files are in the list under "Documents". The data product SIS is the one you want. Another way to get to the data set documents is from the Resources tab. Click on the "View documents" link and then select an instrument to access associated documentation. Getting the image scale is a little trickier. We are developing a tool to provide distance to rover for most stereo images, as well as the ability to measure distances within the scene and to create elevation profiles. Until that tool is ready (planned for later in March), you can get this information by using the XYL image product that is created from a stereo pair. This three-band image contains the x,y,z position of pixels where there is stereo overlap. You can read more information about this in the data product SIS. You can access XYL and other derived products from the product page by selecting "Derived products and download" from "Product views" in the menu. Please ask if you have more questions.
  23. I also would like to see this functionality, and it is on our to do list. There is not a published list that matches targets to images, but we are trying to take data from various sources to make this happen. Your request will bump up the priority. Please email me with your disiderata for Edgar and I will try to help with that request in the short term. Send email to meran -AT- wunder.wustl.edu
  24. The mosaic search function is now online for both MSL (Curiosity) and MER (Spirit/Opportunity). Just go to the Search tab and then scroll down to the block of filters labeled "Mosaics".
