Frail my heart apart and play me a little Shady Grove

Happy π Day!

thanks for the help with the symbols

How is elevation measured on planets with no sea level?

Raq, I will happily defer to greater minds than mine, but my guess is LIDAR LIght Detection And Ranging. (It's how we got our contour dataset a couple of years ago.) Before LIDAR elevation was (and continues to be) calculated with stereoscopic photography, but that's so 20th century...

LIDAR is like radar, only using light. A laser is beamed at the surface (sucking a bit of your soul each time, according to our photogrammetrist), and the time it takes to bounce back is recorded. This is done a brazillian (I'm thankful every day for this nubmer) times as the aircraft flies over the surface. The results are converted into points containing x, y, and z coordinates.

I'm wrong about the tiled picture idea. My sainted former boss believes the full view at google.com/mars is an ugly projection of the entire planet.

Oooh, a mars flythrough. Kewl, lori.

You always do this. We get tipsy, and you take advantage of my love of the scientific method.

The problem is that Verdana's version of π sucks (like the font itself). You need to switch fonts to get a decent looking π.

I look more rad than Lutheranism

Suggestions of how to celebrate Pi Day:

You may want to read a brief history of pi.

You could sing some Pi Day songs.

You could -- nay, SHOULD -- send a Pi Day card! (I suggest you send one to me. Or, well, Nilly, Emily, and Hil are probably more appropriate recipients, but I would squee with pure geek joy if I got a Pi Day e-card. IJS.)

I had arial first, which didn't look much better than verdana. I changed it to times new roman.

Sir, it's not an offence to let your cat eat your bacon. Okay? And we don't arrest cats, I'm very sorry.

Also, behold the Cowpi!

Where do you get the milk?
