Hi all,
Probably not a good place to ask this, but I'm lost. Is anyone familiar
with RPC00B files, which give rational polynomial coefficient
approximations to camera models (in this case for satellite imagery)
relating 2D image to 3D object space. I have the coefficients from my
image provider in RPC00B format, but I don't know the order of the (in
this case cubic) polynomial terms in X, Y, Z (longitude, latitude,
elevation) which corresponds to the coefficient vectors. Is it
a0 + a1*X + a2*Y + a3*Z + a4*X*Y + ... + a19*Z*Z*Z
or some other of many conceivable permutations?
Thanks
Mort Canty

It helps to have a Coyote as an alter ego. Lord knows,
you can always blame it on him!
Cheers,

Irony is dangerous too. I once tried to mimic the male chauvinist in a
textbook I wrote. I thought it was obviously tongue in cheek. Got
accused by a reviewer of being a male chauvinist. I guess the problem
was, he couldn't see my cheek!

Perhaps the winking smiley will help ;)

Oh, goodness, no, I didn't think you were serious.
And, anyway, you had the required emotican to
indicate your intentions. You were perfectly safe. :-)
Cheers,
David
P.S. Let's just say it was pointed out to me again this
week how some people on this newsgroup just don't "get"
my style of discourse. Striving for the humorous is
(apparently) a minefield of danger. But how boring
to live life from a position of safety. It should
always be an adventure. One of my best friends
is totally sarcastic. It's just about the best thing
about him. :-)

Sorry, David (and others). Was just trying to be funny, not sarcastic. (The
question was way off-beat.) It's a wonderful group.

I finally got the info from the image provider. So you can all stop
bombarding me with answers :o)
