Yeah, and was basing a bit of my commentary on it, though the
references might not have been obvious.
It's a helpful system....what Sean is suggesting (in the last post,
some below) is something with even more fine grained potential...

Something I mentioned before is that a lot of satellite based
weather/climate/etc data is now available (and darned if I can't find
the URL's right now... :-P ). It should be possible to grab a lot of
info for a specific point if we can access and process that data (I'm
wondering if there already isn't something on the web that can do that).

Yes, but it would be interesting, and a bit more of a challenge to
calculate "climate similarity/ecological relatedness". Though that is
quite fine grained....I think getting access to polygons (shape files,
from WWF?) and finding which ecosystem type a point is in, is most
accurate...though preprocessing it into a DB table of postal codes
(noting multi-ecosystem overlap within a postal area) is acceptable,
and what the LasPilitas site does..

I believe these functions are now a part of newer MySQL releases:
I'd also like to note that there is an open source map server:
This would be great to incorporate...if there was access to data such
as native plant ranges etc in standardized shape files, or ecosystem
ranges, that would be great to show...
Also, regarding the guild relationship thread...
I'd also be wary of setting up something that might give the sense of a
rigid set of guilds and plants that are within them...we should try to
aim to make the information show people what relationships are
available, and how different plants(+) could add to a guild...
But, I think if we can find available data on species endemic to a
specific natural ecosystem, this would be a good tool to have. One
guild design strategy being to find analogs to the natural plant
communities around you...
OK, 'nough change from my pocket fer now,
