Roger Bagula <rlbagula@xxxxxxxxxxxxx> spake the secret code
<44C18B77.2090601@xxxxxxxxxxxxx> thusly:
Sand dunes are one of the basic examples of geological fractal ddynamics.
Sedimentaion is the basis of Hurst exponents... basically sand being
moved by water.
The sand box model of Per Bak is one of the basic-fundamentals of
modern fractal theory.
Instead of the sand dunes being in air they are in another fluid, salt
water,
but the dynamics are essentually the same.
Yeah, but this news item isn't about any of that. Its just about
mapping. It would be relevant to comp.infosystems.gis (if that's
still around), but its not talking about anything fractal per se.
Using the above reasoning, I could post any story about any aspect of
the earth on a continuous basis because its all non-linear somewhere.
