I tried to make it clear that the circle locations would be "snapped" to
a coarse grid. This means that if the location was 1023.25 km North of
the equator, then we would actually display the latitude as 1020 km
(snapped to a 10km grid) or 1000 km (snapped to a 100 km grid). This
builds in an uncertainty in the area equal to the square of the
grid spacing.

This means that the WEB maps do not show information centered on "exact
longitude and latitude". We do not give away precise information no
matter how small we make the circles.

Practically, this will occur automatically. In a 3"x5" GIF bitmap
of north america, any data is only accurate only to the resolution of a
bitmap pixel. Simply by limiting the zoom factor on the map generator,
it is easy to control how much information is displayed.

Practically speaking, most people would simply not want to wait for
a world map, accurate to 100 meters, to download.

I agree with you completely.

It will be quite accessible.

It will be better than anything currently available.

In time it will become comprehensive.

If experience shows that the information is not being mis-used, then we
certainly have the option of releasing the full accuracy textual database
later on. The limited resolution display is simply a compromise so that
we can go ahead without risking the plant populations. We will be able
to reassess this policy at any time.

The WEB page already has the ICPS statement on plant collecting policy,
plus links to complete CITES documentation. Many conservation issues
are well covered in the various FAQ's. This sort of education is one
of the charter purposes of the ICPS.

This is on both the WEB and the listserv archive. There is even an
extensive discussion of one particular nursery that is known to field
collect extensively.

> * Private collectors who sell and trade their plants

The listserv (or rather I) maintain a compilation of growlists from
anyone who sends me their growlist in a standard ASCII format. We have
perhaps 20 growers already in the database, sorted by species and
availability:

This is also on the WEB. See Ivo Koudela's bibliography, check out the
cp.sellerlist, the cp.growlist, the cp.suppliers list on Chris Frazier's
FAQ page and the listserv archives.

This is on the CP WEB. I spent several weeks of free time and considerable
expense developing the CP Tissue culture tutorial at:

Look at the CP FAQ's, especially those maintained by Chris Frazier and
Barry Meyers-Rice

I and many other volunteers have spent *thousands* of hours work
trying to do this. Everything you've mentioned already exists in
some form - all linked to the CP WEB page. In most cases, the information
is constantly improving and getting easier to use every day.

A half-dozen volunteers have worked over three years getting the
CP-source database in place. (not to mention Jan's work of decades).

We're only now turning our focus towards field data.

The WEB page is not a "closed" project. I've always welcomed, and
installed contributions from anyone that wants to improve the material,
or fill in holes. It's a *group* effort.

Unfortunately, the presentation wasn't good enough for you to find these
resources yourself. Please take another look, try to identify the
weaknesses, and get back to me. I'd be happy to try to implement any
specific improvements that you might suggest.

Best regards,
