METADATA FOR UNFRAGMENTED LANDS OF RHODE ISLAND


A.  Identification and Description

1.	RIGIS-CAT-ID	
2.	DATA-SET-IDENT	unfrglnd
3.	DISTRIB-NOTES	
4.	THEME-KEYWORDS	unfragmented lands, habitat resources
5.	DATA-SET-DESC	Unfragmented lands of Rhode Island.  USGS 1:24,000 road coverages were used 
to define the boundaries of land blocks.  Blocks of land with population density 
less than 40 persons per square km were used in this analysis.  The percentage of 
natural land for each block was calculated.  Natural land information was 
derived from 1988 landuse data, and includes forest, idle agricultural land, and 
wetlands.  The land use data were delineated from 1:24,000 scale stereo aerial 
photography.
