FGDC Metadata for USFWS_92






Originator: US Fish and Wildlife Service and National Biological Service

Title: Lower Mississippi Valley Landcover

Description: Abstract: These landcover data were classified from 2 season (spring/fall) 1992 TM data at 30m resolution. Forest and some agricultural lands were classified using supervised classification in TNT-MIPS. Remaining agricultural lands classifications are from independent classification of 1992 TM data by USDA-NASS and University of Arkansas-CAST.

Note: TENS_FOR and TENS_H2O were extracted by The Nature Conservancy - Baton Rouge office only for the Tensas Basin from the original 30 m pixel data. Forest in TENS_FOR was drawn from classes 123456789,10,11,12,13,14,15,16. Water in TENS_H2O was drawn from classes 22,23,24,26.

Purpose: These data were developed as a tool to delineate wildlife habitat.
