PURB - Percentage of urban The percentage of urban land cover is calculated by dividing the
number of urban land cover cells in the 1 km grid cell reporting
unit by the total number cells in the grid cell boundary minus those
cells classified as water (total land area). High amounts of urban
land indicate substantial modification of natural vegetation cover
and may have profound effects on wildlife habitat, soil erosion
and water quality. |
