MOC STRIP M08-06569

http://www.msss.com/moc_gallery/m07_m12/mc02.html

Should you wish to access the M08-06569 discovery evidence via a graphical browser interface, the MSSS Mars Chart 02: Diacria is a very good one and located at the above URL address. Note the location of the M08-06569 and M08-06570 strip pointed out with an arrow in the chart. This area is a relatively level region known as the Arcadia Planitia plains.

OFFICIAL SCIENCE DATA ACCESS SOURCES FOR THIS STRIP

The above MSSS (Malin Space Science Systems) URL will take you directly to the desired science data image. For M08-06569 at this location there are three strips to choose from and all work. The first listed medium quality but faster loading JPEG and the second listed best quality but slower loading GIF sinusoidal (angled) projection strips work and have an orientation that agrees with the companion M08-06570 context wide-angle image. However, the third listed better quality but slower loading GIF straight vertical strip has been flipped at official level and also note that this is the strip that is also found at PDS and USGS simply because it is straight and more suitable to the their presentation formats. Note that the companion M08-06570 context wide-angle strip can be found at this same location. Be aware that MSSS uses the newer MOC context wide-angle images rather than older Viking context images used at both PDS and USGS.

If there is a way to access a MOC image strip directly at PDS (Planetary Data Systems), I do not know it. The only reasonably describable method I know of to access a specific MOC image at PDS is to go through a search process from their "Planetary Image Atlas" page at the above supplied URL address. On that page in the first Mars Global Surveyor section click on "Forms Search Interface" under Data Access Links. On the search page that comes up enter the Latitude coordinates 39.26 in the first left and right fields and the Longitude 152.43 in the second left and right fields. make no other entries, and then click on the "Submit" button at the bottom of the page. The next page that comes up will have a pop-up window, you should close that and then click on "View Thumbnail." That will bring up the true browse page for the M08-06569 image strip. From this page you can choose the default GIF browse image but just clicking on the "Submit" button and do nothing else. Alternatively, PDS is unique in that you can specify other types of images in the two drop down menus there. Just remember that the straight vertical GIF images in the earlier series of MOC imaging are often but not always flipped versions.

The above USGS (United States Geological Survey) URL will take you directly to the desired science data image. However, note that the browse image there is straight only and medium quality JPEG, it is flipped, and there are no other browser compatible images available, only the full proprietary"Standard Compressed Data Product" as USGS calls the PDS format science data image, which you will need special NASAVIEW software to view. Their approach is that the JPEG browser image is used for a initial look tool but if you really want to view the strip seriously, you will use the PDS image. In other words, this site isn't the most friendly for visitors using only Web browsers. Still, one advantage here is that the JPEG browse image is divided up into parts and that style can be faster and therefore more convenient if you do not wish to look at the whole image and wait for it all to download.
