In: Global Ecosystems Database Version 1.0: Disc A. Boulder, CO: NOAA National Geophysical Data Center. 11 independent single-attribute spatial layers on CD-ROM, 2.9 MB. [first published in 1988] Analyst: Mark Ohrenschall Projection: Geographic (lat/long), GED window (see User's Guide). Spatial Representation: Averages over 1-degree grid cell areas Temporal Representation: Modern composite Data Representation: (1) Animal Density: Number/km2, with precisions up to 10-7; expressed as 4-byte IEEE real numbers to 10 significant digits (2) Methane Emission: Kg/km2, +/-1 Kg/km2, expressed as 4- byte IEEE real numbers Layers and Attributes: 11 independent single-attribute spatial layers Compressed Data Volume: 130,257 bytes ADDITIONAL REFERENCES NONE TECHNICAL REPORT Mark A. Ohrenschall 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 versions. *LERNER ET AL ANIMAL METHANE ANCILLARY ENVIRONMENTAL DATA Lernet et al Animal Density #*ANIMAL DENSITY Lerner et al Annual Methane Emission #*ANNUAL METHANE EMISSION Scanned Documentation #*LMF SCANNED DOCUMENTATION *LMF SCANNED DOCUMENTATION_help 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 Paintbrushformat 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.) *LMF SCANNED DOCUMENTATION LERNER ET AL ANIMAL METHANE Page 1 #\document\ncillary\lmf\lmf_01.gif Page 2 #\document\ncillary\lmf\lmf_02.gif Page 3 #\document\ncillary\lmf\lmf_03.gif Page 4 #\document\ncillary\lmf\lmf_04.gif Page 5 #\document\ncillary\lmf\lmf_05.gif Page 6 #\document\ncillary\lmf\lmf_06.gif Page 7 #\document\ncillary\lmf\lmf_07.gif Page 8 #\document\ncillary\lmf\lmf_08.gif Page 9 #\document\ncillary\lmf\lmf_09.gif Page 10 #\document\ncillary\lmf\lmf_10.gif Page 11 #\document\ncillary\lmf\lmf_11.gif Page 12 #\document\ncillary\lmf\lmf_12.gif Page 13 #\document\ncillary\lmf\lmf_13.gif Page 14 #\document\ncillary\lmf\lmf_14.gif Page 15 #\document\ncillary\lmf\lmf_15.gif Page 16 #\document\ncillary\lmf\lmf_16.gif Page 17 #\document\ncillary\lmf\lmf_17.gif Page 18 #\document\ncillary\lmf\lmf_18.gif *ANIMAL DENSITY_help DATA ELEMENT: Animal Density STRUCTURE: Raster Data Files: 1-degree GED 180x360 grid (see User's Guide) SERIES: Animals SPATIAL META-DATA: LMFCAML.DOC file title : Lerner et al Camel Density (1/Km^2) data type : real file type : binary columns : 360 rows : 180 ref. system : lat/lon ref. units : deg unit dist. : 1.0000000 min.
