The lidar is intended to return surface elevation for waterbodies; however in this instance there is a reflectance error. A corrected value for the surface elevation of 579.26 was calculated using a constant value raster. The original 3 tiffs are available (18508225.tif,18508250.tif, 18758250.tif).<\/div>",
