Tom Stein's Achievements

  1. 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
  2. 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.
  3. 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.
  4. 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
  5. 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
  6. 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.
  7. 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?
  8. 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.
  9. 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.
  10. 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.
  11. 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
  12. You can find the raw image archives at the PDS Cartography and Imaging Sciences Node: https://pds-imaging.jpl.nasa.gov/volumes/msl.html
  13. 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.
  14. 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".
