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

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!

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.

It's like she's following a coastline, isn't it?

Really need to see some new images soon. I'm going mad here, Ted, mad I tell you...!

Looks like they are aiming for that meandering crack formation, but higher up where there's no sand obscuring it.

If memory serves, someone, somewhere, once anticipated that Opportunity would follow along this very coastline...

So we are back on track.

Rui, perhaps it's time for another update of this map.

Here's an update corresponding to sol 2393 and also including the 24km mark.

Today's drive was once again on the 100m range. Here's a preliminary map update; of course, it still has to be adjusted based on the "ground truth".

Moved a few posts dealing with travelled distance / 100 sols to this thread: Some Statistics for Spirit & Oppy

The clock has just ticked past midnight and so sol 2400 has begun. As no driving is planned tosol I'll post the update to my large scale 100 sol (hectosol? ) route map now.

As was mentioned a few days ago the progress over the last 100 sols has been fantastic. Almost exactly half the distance to Santa Maria has been covered since sol 2300 and the 'parking lot' is now very close.


Both images link to the same blog post with links to larger versions.

Here's the latest map from the Ohio State University: http://shoreline.eng.ohio-state.edu/album/...03/opp_2375.jpg
It's from sol 2375. Usually it was available through the MER main site, but this one I didn't see in the Opportunity traverse map archive. The last was published in July.

We have now reached 53,1% of the distance to endeavour crater, yeah!

And here's my version from sol 2401. The current position is already corrected by means of the navcams.

At the bottom right of Tesh's map you can see the start of the parking lot. Just 300ish meters away!

Yes.
That's the reason why I posted a bigger crop.

I really appreciate that. I know we can't have one every time, but a series of overlapping ones about that size at intervals of 5 or 6 drives would be nice.

Remember - there is always the KML

I know I'm at the back of the class but I won't be shy. What is a KML?

Keyhole Markup Language

It's the file that ET has been attaching to every map update for months and months, and loads directly into Google Earth (once you've added on the local maps for Opportunity ) so you can see the route for yourself, as much or as little as you want.

This shows you what you can do with Google Earth and Eduardo's .kml files, Nigel...

Thanks all re KMLs. My system comes up with 'unknown file type' when I click on those. However I do greatly appreciate 'Road to Endeavour' which is always admirably clear and instantly accessible.

Thanks, but I have to stress it's only because of Tesheiner's brilliant work with those KML files that my blog is of any use to anyone!

Here's the map update corresponding to sol 2402.

Mmm, don't you have Google Earth on your computer?

Not the right version, apparently.

Now that Opportunity has almost reached the flat parking lot / tarmac I thought it was time to post again the "biggie" map. It is updated up to sol 2404.

Edit: Here's an updated KML file with a corrected position for sol 2404. The "mobility data" was off by around 5m.

Cool. For those who want to follow the trek of opportunity I have this tip: Just save the new big map from Tesheiner to your desktop. Every time he posts a new small map of the current progress, just open it, copy the picture and paste it into the big map. The alignment is easy. This is done within 30 seconds. I made this the last half year. You always have the the current route as picture and always the context of current drive.

Thanks for this excellent idea, especially since Google Earth is working awfully for me with the overlays. My Mac Pro is loaded with 5 GB of RAM, but freezes up constantly in GE. Can't figure it out. I delete the overlays and it works great. Still waiting for the folks at NASA to embed the detailed overlays right into Google Mars' servers! That's gonna be great.

I'm currently using the overlay created while testing the MapTiler tool (see this post) and it works quite smoothly. Let's see if I can make it available.

And back to the business of this thread, here's a crop of the map around sol 2405 and the corresponding KML file.

ADMIN: Several unproductive posts moved to the "Kitchen Junk Drawer" thread.

There's still not enough images to confirm the position after sol 2410, but if we trust the rover's mobility info here's our current site.

You may like to download these updated versions. I revised the end position on sol 2020 with the help of nav/pancam mosaics and also added the leg around Intrepid.
