HEADWATERS ECONOMICS GEOGRAPHIC DATA LIBRARY DOCUMENTATION TITLE: Geodataset Name: na_cmp_prod Geodataset Type: GRID Geodataset Feature: NA GENERAL DESCRIPTION: This dataset describes areas of overlap in two layers that represent productivity: (1) greeness (calculated from satellite imagery), and (2) average net primary productivity DATA SOURCE(S): World Wildlife Fund Carlos Carroll Scale of Original Source Maps: 1:1,000,000 Date of Original Source Maps: 1999 - 2004 GEODATASET EXTENT: Western North America FEATURE ATTRIBUTE TABLES CODES AND VALUES: NA DATA LINEAGE SUMMARY: The input datasets represent productivity. In order to create the final dataset showing the areas of overlap in these two ecoregional assessment layers, two binary grids were created and added together (the thresholds below were chosen to select approx. 25% of the Brainerd funding region): (1) (greeness > 950) and (area > 50 square kilometers) (2) average net primary productivity > 187,000,000 kg of carbon MAP PROJECTION PARAMETERS PROJECTION ALBERS CONICAL EQUAL AREA DATUM NAD83 UNITS METERS SPHEROID GRS1980 PARAMETERS 1st standard parallel 29 30 0.000 2nd standard parallel 45 30 0.000 central meridian -96 00 0.000 latitude of projection's origin 37 30 0.000 false easting (meters) 0.00000 false northing (meters) 0.00000 DATA SOURCES CONTACT(S): Name: World Wildlife Fund - US Address: 1250 24th Street, NW Washington, DC 20037-1193 Web site: www.worldwildlife.org/science Phone: 202.822.3452 Email: nasser.olwero@wwfus.org Name: Carlos Carroll Address: Klamath Center for Conservation Research Orleans, CA 95556 Phone: 530-627-3512 Email: carlos@klamathconservation.org Web site: http://www.klamathconservation.org/ HEADWATERS ECONOMICS CONTACT: Name: Headwaters Economics Geographic Data Library Abbr.
