  1. 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.
  2. 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.
  3. 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.
  4. 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
  5. You can find the raw image archives at the PDS Cartography and Imaging Sciences Node: https://pds-imaging.jpl.nasa.gov/volumes/msl.html
  6. 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.
  7. 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".
  8. 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.
  9. 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.
  10. 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
  11. 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".
  12. Hi Jun - We will check on the account creation and see what's going on. For the second part, I just started adding a "mosaic" category to the data search form this past Thursday. We'll put that function online as soon as we get it tested. Besides searching for anaglyph mosaics, are there any other filters or constraints you'd like to see included in the mosaic search?
  13. Hi ocpaul20 - Would you please post an example that you'd like to see worked through?
  14. The REMS RDR data were not available to add to the Notebook at the initial release. They now are online.
