都市域における水の指数について

The triangular distribution of the data are found on a NIR-RED scatter plot by using the Landsat TM data in the urban area same as in large scales of vegetation areas. The PWV could be thus proposed as a water index in urban areas. The index could indicate location of small water bodies because it sensitively increases with water surfaces in the land. The water index could be thus effectively used for evaluating management of environmental water circulation in urban areas.
