Kilometers on the ground Options

[Glevesque]

Hello everyone !

I would like to know more about the mileage grid on the ground. I have difficulty finding precise data from various unofficial sources.

Here is my list:

______________________________________________________________________________
Bonjour a tous !

J'aimerais avoir des précisions sur la grille de kilométrage parcourus au sol. J'ai des difficulter a trouver des données bien précises à différentes sources non officiel.

Voici ma liste :

Hello again,

The discussion is this thread prompted me to thoroughly review the km and mile signposts in "The Martian Way" kml file, especially at the light of new (to me) information in the articles by Vasavada, A. R., et al. and Rice, M. S., et al. which provide sub-meter accuracy for the total traversed distance for sols 0-494 and 535-634, respectively. The former allows very precise location determination of kms 0 through 4 and miles 1 and 2; the latter extends this to kms 5 and 6 and miles 3 and 4.

Additionally, starting with sol 1282, the description on NASA/JPL Location and Traverse maps ("Where is Curiosity") includes the total traversed distance to an accuracy of 10m. In this way good estimates for kms 13 to 17 and miles 8 to 10 can be made.

Km 10 was abundantly mentioned. Thus I "only" needed to "guesstimate" the locations of kms 7, 8, 9,11, and 12, and miles 5, 6, and 7. This proved to take a lot longer than I antecipated, which explains why I have not made any recent updates to Curiosity's GE path. Phil Stooke's maps have several of the guessed kms, which is good corroboration - thank you Phil. Despite doing my very best, errors may exist. I have after all, "guesstimated" several locations. I would be very thankful for any information that could improve the accuracy of those locations.

In short, here is the revised list of kms and sols:
1 335
2 365
3 404
4 436
5 540
6 587
7 655
8 670
9 743
10 957
11 1098
12 1248
13 1376
14 1448
15 1526
16 1666
17 1754

And here is the complete list, with information sources. To use it, dowload it and drop the ".txt" from its name.

Edit: Something I've learned: in the Analyst's Notebook odometry or total odometry is not equivalent to traversed distance. The former really does exceed the latter.
