Thinks this is very cool. He wants me to pour over our maps to find you what you need so this can happen. I was lost at "using robot localization to create a canoe o cheat bot, where using the estimation techniques and bearing and distance estimates."

Mr Wonderful:
I had an idea of how to do it in the woods on a trail, using an altimeter to transition between contour line sets (eg, at elevation 900, use this interval, at 915' use the next +5m). Then it all falls apart on hill tops, but if you are billing your service as a cheater, it would be an enhancement, since on hilltops the orienteer can handle the navigator better, versus in the trenches when the orienteer can't see as far.

So maybe that would work. And then the newest technique we learned should be good for that scheme.

But I have to convince one other kid to want to do this too, which might be the bigger issue! <---the social worker training would be much handier for this part

Mr Wonderful:
The part where I lost you isn't any different than what you do in the woods, just worded poorly.

If you are on a trail headed north and pass a reentrant, and think you see a veg boundary, but there aren't veg boundaries north of the reentrant on the trail you think you are on, maybe you didn't see a veg boundary. You give low weight to your new observation. But if you are pretty sure you see the veg boundary and also see a fence that's not north of your reentrant, maybe you aren't where you thought you were, and are instead on some trail with those features there. That sort of thing.

And the one we just learned is the same idea as o relocation - I can see these three things, which means I could be in these four places. So I'll move this way and then see what's next, which might eliminate some of those options, hopefully converging to one most likely spot.
