Water Depth Mapping

This service calculates the water depth in areas around given locations.

Given locations of interest, the algorithm is run using Sentinel-2 and a DEM to return images with values that represent water depth. The images are provided as a GeoTIFF file with band 1 containing the estimated water depths, band 2 a quality indicator (a value of 0 indicates that the water depth at the pixel could not be calculated, 1 indicates the value was calculated and 2 indicates that water was present at the location but that only a minimum depth could be assumed), band 3 the difference between the current estimate and the last (negative values indicate water depths are dropping) when a last estimate was available, band 4 the smoothed change in water depth and band 5 the associated elevation data. Additionally a GeoJSON and CSV file are generated with the minimum, mean and maximum water depth.
