Service Description: This tile layer is made up of pseudo-color infrared satellite imagery covering a large portion of southeast Louisiana. This scene was taken by the Sentinel 2A satellite, part of the Sentinel 2 mission operated by the European Space Agency, just before 5pm on August 14th, 2016. On August 11th, 2016, a mesoscale convective system flared up in southeast Louisiana and remained nearly stationary, dumping unprecedented levels of rain in areas near Baton Rouge. An estimated 75% of homes in Livingston Parish alone were destroyed. 

The original multispectral image was downloaded from the USGS EarthExplorer website. It was then visually processed in ArcGIS Pro and published as a web service. Sentinel-2A senses electromagnetic energy from 13 different bands that have varying spatial resolutions of 10, 20, and 60 meters. To aid in viewing flood waters against dry ground, the specific bands used and the colors they are assigned to are: Band 8 - Near Infrared (Red), Band 11 - Shortwave Infrared (Green), and Band 4 - Visible Red (Blue). This specific high contrast combination allows water to be visualized as dark violet, and land to be visualized as warm amber orange (highly commercialized areas appear green-grey). While a majority of the complete image is obscured by clouds, the areas in and around Baton Rouge are unobstructed enough to see the many places covered by floodwaters. 

This image was split into 15,296 individual tiles and has a zoom level range of 0 - 15 (World - Neighborhood).
