Backscatter imagery extracted from gridded bathymetry of Ni'ihau Island, Hawaii, USA. These data provide almost complete coverage between 0 and 100 meters. The backscatter dataset includes Simrad EM3002d, Simrad EM300 and Reson 8101 data. The sonars frequencies are 300 kHz,30kHz and 240 kHz respectively and are processed and gridded separately. Because of the similar sonar frequencies the data can be mosaicked nearly seamlessly using GIS software. This metadata is for the Reson 8101 backscatter data only.
