Date of Image: 3/21/2019 Date of Next Image: Unknown Purpose/Summary: Modified Normalized Difference Water Index (MNDWI) provides a different view of the Earth's surface combining different bands to make water bodies more obvious. This index can be used to identify flooded areas as well as heavily saturated areas. Suggested Usage: Areas of existing water, such as a rivers or lakes appear in the darkest green with high values near 1, while dry land appears in the darkest brown with low values near -1. This product can be used to identify potentially flooded areas that can be seen in varying shades of green and light brown depending on the amount of moisture picked up by the satellite. Satellite/Sensor: Landsat 8 Operational Land Imager (OLI); 30m resolution Credit/Acknowledgments: NASA/MSFC, USGS |
