Look just SW of the third green triangle - that's where we are.

A magnified region of PIA17355 patched with a reduced version of Phil's latest map:

That is extremely helpful, thanks Gerald! I hope you'll consider posting more of these from time to time.

There is clearly no doubt that Phil's map is correct for the Sol 527 drive, but I wonder why Joe's Sol 527 drive map, based on rover data, is so far off? Is the underlying map incorrectly positioned? I can't imagine the rover data is that wrong.

You're seeing a symptom of no bundle adjustment. Every now and again trajectory data will be updated and nudged around to reflect the true location of the vehicle versus it's own ready-reckoning version of where it thinks it is (and where early SPICE data might show it to be)

Map update to sol 528. (EDIT - last point should be labelled 528, it's fixed in the sol 533 map below)

That error in Joe's map is cumulative over a long period. I might be tempted to multiply the distance travelled each sol by some factor like 0.98 and adjust the factor iteratively until it gave me a closer match, if I were doing what Joe is doing.

While there's no errors in the telemetry you have to keep in mind IMU drift (which periodically reset) and Visual Odometry is not always used. After almost 5 Km (hint hint!) this starts to add up. Also, after 5Km (more hints) you will begin to notice misalignment between HiRISE and surface North.

Map update to sol 532 - a small move back to inspect the tracks and wheels before - drumroll- like, whatever. Argyle is the target in the scuff. (oops, meant to label the Argyle site 528-531. I'll fix it tomorrow.)

This is a quick, possibly slightly premature, update to sol 533, with yesterday's mistake corrected.

A wee close-up of Dingo Gap. Some of the fine details of the drives may not be exactly right but this shows what I know so far. The scale is a bit off in the corners, so think of this as an approximation until I get better topographic control.

Work in progress here.
Picking up on the great quality maps, as usual, you guys have been publishing, I've produced a map to, yes I was lost, help getting a broader idea of where we are, not at the same level of detail we're seing on this thread. Any correction or suggestion?
And where's that damn abyss?... smile.gif

Nice map! I would like to see it a bit bigger if possible.

Here's an update to sol 535.

Thank you Phil, here it is.
Been out for too long, I've used ESP_034572_1755, is there an HiRISE that takes us further West?

I'm using ESP-018854-1755-ortho at the moment.

Phil

(EDIT - very quick route correction to my map in the post just above - I replaced it with a corrected version soon after posting it)
