Phew! I could only rule out 50% of our Earth so far.


70% actually, because it's obviously a feature on land somewhere :)

Okay... another hint... It was all about accurate measurements...

I think I need at least another zoom level or two . . . .

Ok wild guess,
There was a French expedition in Peru ( 18th cent. ?) whose mission was to create a then state-of-the-art measurement of the Earth by triangulation. They started by creating one very accurate baseline (1km ?) somewhere at the equator in South America.

I too am thinking geodesy, but was also thinking linear particle accelerators :lol:

More zoom levels would just show more trees, it's kinda in the middle of nowhere... Well... as "nowhere" as you can get in that particular place anyway...

A Cartotalk cupcake for Jean-Louis, he's identified the field of work connected to this feature (geodesy). Unfortunately he's on the totally wrong continent. Also... the French didn't have anything to do with it.

I'm throwing in the towel, or better yet, a soft map blanket! :P

does it have anything to do with the accurate measurement of the velocity history of a laser-driven foil plate with a push-pull-type VISAR?

Or am I just way off?

Well, putting the two together rules out nearly 85% of the planets surface! Yay!

What kind of measurements are so large? The Ur-Meter is definitely not this size...

It's fairly close to my previous challenge... if that's going to make it any easier...

Some kind of construction not too far from Holland but not France in an unpopulated area which had to do with some kind of accurate Geodesic measurements but was outdated by the time it was completed and therefore never used.

I googled every possible combination of these clues...nada

Ok Hans.... everybody's stumped...cough it up!

Whew, I've found it -- that was a tough one. It's a place called Loenermark, NNE of Arnhem. Here's an article on it:

Let's hope your right - I looked around Stroe a bit and didn't find it, but noticed an area NE of the town that does not want to be seen.

It's at 52.078873°N, 6.0030842°E: http://www.wikimapia...p;search=arnhem

Once things got narrowed down to the Netherlands, I found it by just browsing the more remote, forested areas.

Congratulations Michael, you found it!

It's a calibration base constructed in the late 1950's to be able to calibrate surveying equipment. However, due to the rise of electronic rangefinding methods around that same time, it was never actually used and was left to deteriorate. Last year it was sort of brought back into the collective conscience of the Dutch geo world and an information panel was placed at the site.

Here's a new one. I'll give some extra clues if needed.

Hmmmm. A volcano with a ski lift. I first checked New Zealand, then Peru. Perhaps a hint would help...
