NOTES:
(1) The above legend category information is in a
hierarchical classification system. Each legend
category consists of a major heading with up to three
additional sub-headings, each heading being separated
by a unique delimiter character ("|") in the legend
category description. All legend categories that fall
under any particular heading have that heading repeated
in the legend category description. An example will
illustrate this. In the classification structure 5.D
has the major heading "FORB FORMATIONS", but there is
no vegetation class in the data set for this category
and so it has no legend category. However, 5.D.2 "Low
forb communities (<1m)" (a sub-heading under "FORB
FORMATIONS") does have a vegetation class in the data
set (number 175) and so the legend category description
reads "FORB FORMATIONS | Low forb communities (<1m)".
Furthermore, 5.D.2a "perennial flowering forbs and
ferns" (a sub-sub-heading under "Low forb communities
(<1m)" under "FORB FORMATIONS") also has a vegetation
class in the data set (number 176) and so the legend
category description reads "FORB FORMATIONS | Low forb
communities (<1m) | perennial flowering forbs and ferns".
(2) The above legend information reflects minor revisions
from that presented in Mathews (1989).

TECHNICAL REPORT
Mark A. Ohrenschall
NOAA National Geophysical Data Center
Boulder, CO
Data were read from floppy disk and converted to the GED format,
separating each variable into different GIS files without
altering the original numerical values. Legend information was
entered from the accompanying documentation. All final data
files were inspected for agreement with the original data. The
methane emission spreadsheet (see DATA ELEMENT: Methane
Emission, above) was entered by hand from Table 6 in Matthews
(1989).

The scanned documentation noted here is contained in the \document
directory on the CD-ROM as .gif files. These files can be read by
any computer program that reads PC Paintbrush format files.
The GeoVu software provided on this CD-ROM contains such a utility.
To use the GeoVu utility, merely select the appropriate file from
this menu, using the "Open Data" option that you have been using to
this point.
If you are VERY NEW to GeoVu, you can open a file by
1. Selecting "File" from the options at the top of your screen.
2. After selecting "File" select "Open Data" from the options that
appear in the pull-down menu.
3. Follow the hierarchy of menu paths to the data of your choice.
4. When the hierarchy leads you to a topic "Scanned Documentation"
merely select that topic. The next topic should read "Page 1, Page
2,... etc." or "Paper 1 Page 1, Paper 1 Page 2, .... Paper 2 Page
1.... etc. You can select the pages manually, or create a "slide
show" under the Utilities option at the top of the screen. The
first time the .gif file displays it might be reduced in size. This
is a "feature" of current versions of GeoVu that might be improved
in the future. If you redisplay the image (by selecting "Search"
from the options at the top of the screen, then "Create" from the
menu thus pulled down, you can modify the parameter that sets the
sampling rate from "n" [usually 2, 3, 4, or 5] to 1). This will
give you full resolution display of the scanned documentation.
It should be noted that this scanned documentation is a compromise.
We originally attempted to use optical character recognition
software to convert the scanned documentation to more usable text.
However, the technology was too immature at the time of scanning
(1992) to use successfully. Indeed, as of this writing (late 1995)
the technology is still too immature for convenient application to
this problem.
Thus, we present the scanned documentation as images.
NOTE: Many of the original documents are not copyright, and may be
reproduced freely. However, several other documents ARE copyright.
The National Geophysical Data Center has obtained permission to
reproduce all documents with a valid copyright. However, this
permission does not pass automatically to anyone else. Thus, though
all of the data on this CD-ROM are unrestricted, much of the
scanned documentation (which contains copyright notices) may not be
distributed further, without permission of the copyright holder, or
without a dontribution made to the Copyright Clearance Center under
the rules noted in the individual papers. (Also note that a few
documents authored by U. S. Government employees or contractors as
part of their work for the Government, had copyrights claimed by
the journals that published the papers. Such documents are not
subject to copyright, and the copyright claims of said journals
have been determined to be meritless.)
