Percent herbacious cover calculated from VCF MODIS 2001 herbacious cover classes. Native resolution is 500 meter projected in Geographic Coordinate System Sinusoidal WGS 1984.

Processing Procedure

1. In ArcMap 10.0, convert GLU gird to Sinusoidal WGS 1984 in 30 arc second resolution.

2. Use zonal statistics to calculate mean values within each GLU.

Data Coverage

Data is coded by the number of cells covered by the native data (1), data extrapolation (2), and not covered by either (3).
