The polygon represents the extent of inundation due to Mean Higher High
Water (MHHW), after a 1.4 meter sea-level rise (scenario for year 2100),
for the California coast (excluding the San Francisco Bay). The current
inundation due to MHHW was based on NOAA tide stations elevation data
(mhhw_2000 raster), to which 140 centimeters were added to the Z-value
to generate this data.
