Map of habitat heterogeneity across the conterminous U.S., based on 30-m resolution standard deviation texture (21x21 moving window) of NDVI (index of vegetation greenness) from Landsat 8 imagery. Darker green areas indicate regions with higher habitat heterogeneity.

Mapping habitat heterogeneity using image texture

Laura Farwell is using image texture measures as powerful predictors of regional and global biodiversity patterns.
