Now we are down safely I am starting a map thread. Everything that happens during 2021 will be covered in my still-in-progress atlas, so I have to make the maps for that and everyone can follow as they evolve.
Let me know if any feature names start to show up. Preliminary map even though not much has happened yet. But if you look closely you will see something, even now. Phil -------------------- ... because the Solar System ain't gonna map itself.

Following up on registering as accurately as possible a well suited rover downlook map image I thought it may be useful to easily look up coordinates and measure distances on the map. Here is a bare bones web app (takes a bit to load) to do that:
http://bit.ly/PercyMAP with reduced texture for mobile http://bit.ly/PercyMAPm It is made using https://www.x3dom.org/ and a little javascript. One can zoom in (wheel or right mouse drag), pan (middle mouse drag) and re-center (double left click). The coordinates of the cross-hair are reported and left clicking adds the current position to a list, and calculates the distance from the last recorded point. For example, it turns out that the wind-carved walrus boulder (harbour seal) is about 12m away from the rover. The used HiRISE DEM has nominally a 1m resolution but seems smoother than that in places, perhaps not picking up all boulders. I may add a few additional features (controlling shading, continuous reporting of distance to rover) but nothing fancy to keep it really simple. [edit] There is now a slider to control vertical exaggeration of the elevation model. -------------------- --
