Kinda playing around with the 13km South line, eh?

[Tesheiner]

And the 2km East too.

Ouch! Stop it, you're making me crazy!

Seriously, I've often wondered something about your route maps, Tesheiner: You often show a single sol's drive in multiple segments, rather than just a straight line. On the 2377 drive, the imagery isn't even down yet, so obviously you used the downlinked drive data. I'm curious how the downlinked data is presented: do they provide the distances E/W/N/S for some number of drive segments? Do the segments always correspond to turns?

It's really nice to see that level of detail in your maps.

Edit: one more thing: you forgot to include the kml file with your last map update!

I'm curious how the downlinked data is presented

For each picture taken during a drive (e.g. slip-check navcams, post-drive pancams) the (x, y, z) position calculated by the rover itself and relative to the site origin (AR00 in this case) is provided.

That's the easy part in the process of updating the route map. The "hard" one starts afterwards when the pictures are available at the exploratorium; then it's time to make a navcam mosaic, convert it to polar projection and register this picture on a HiRISE image at full resolution. The reason to do it is because the position calculated by the rover itself almost always drifts. E.g during the drive on sol 2375 I had to adjust the final position by 2.5m to the east and 1.5m to the south. It's not too much on a single drive but without these corrections and using only the "telemetry" the route would be way off after a number of driving sols.

A wee correction to our wonderful route maps...

Ray Arvidson has a very nice presentation of Opportunity's traverse at the 4th MSL workshop site:

http://marsoweb.nas.nasa.gov/landingsites/...roscopy_opt.pdf

He shows Solander Point as a northern spur of Cape Tribulation. So when the tracking website indicated that an image was looking at Solander Point, it was that, and not the small crater in front of the rover at that point.

Thanks for pointing that, Phil. Maps updated.

Well worth the watch. Thanks for posting that.

Here's the update for sol 2379.

Here's a preliminary update for sol 2381. I'll probably have to adjust it slightly after the pictures are down.

There're some data from sol 2383 but not enough to plot the current position. Perhaps tomorrow.
