Sean, at this rate someone will need to rename the header "AMAZING IMAGES" from "interesting images!"

Sean, with the discussion on Arsia Mons, is there DTM data? Could you do a flyby, esp. of the SW flank where the clouds seem to be starting? Thanks!

Sadly there's no HiRISE DTM's of the area.

Some HRSC Images do though.... -

There may be others according to HRSC View.

It might be a while before I can look at that area, any decision to render will depend on data coverage/quality & aesthetic.

Congratulations Seán! And many thanks for taking this topic.
I posted pointers to the video on the Zooniverse PlatetFour:Ridges project's chat.
I expect volunteers to be ecstatic, as I am. It is so much nicer to see them with perspective!

While working on classifying subsets of CTX images on the PlanetFour:Terrains and PlanetFour:Ridges projects on Zooniverse, I often need to visualize the full CTX or search for nearby CTX or HiRISE images.

That used to be easy using the image explorer from ASU. Having loaded the reference CTX with the image explorer, I just clicked the "View this image in context on an interactive map" button. Sadly this capability seems to no longer be working for CTX and HiRISE images, despite still being available for THEMIS.

Does anyone know what happened or how to bypass an eventual problem? Thanks
Fernando
Update: the capability has been restored. Thanks are due to those making it happen! smile.gif

It seems that the correction to MRO CTX Viewer problems I mentioned in Post #142 did not catch everything.
The "View this image in the context of an interactive map" button now works almost perfectly. It does open a map, but it is centered on the wrong coordinates.
For instance, for image F13_041029_0968_XN_83S057W the map opens centered on 83.3º N / 302.5º E. North when it should have been South.
The absolute value of the latitude is used to position the map.
It would seem the code is parsing the image ID but fails to take the N or S indication into consideration.
Perhaps some viewer of this forum knows someone able to fix it? Thanks.

Perhaps this is related to the direction in which the HiRISE strip is captured? Some have North up and some South up. That information is present in the .LBL file. I don't think it is possible to determine it from the file name.

Thank you Paolo. I am aware of this "image flip", I believe it is not it. I really do not know what is causing it, but several of the PlanetFour:Terrains project's volunteers (myself included) are heavy users of the viewer. It is quite handy to view the CTX in context in order to find near ones and overlaps. The CTXs used by the project are from the south pole area, so we were surprised to be taken to the north polar area!

Testing some new rgb / synthetic rgb blends...

Medusa Fossae


For the 3D texture I target HiRISE rgb and build out a synthetic rgb map then blend in Photoshop.
