  <dc:description xmlns:dc="http://purl.org/dc/elements/1.1/">Remotely sensed variables and ground truth samples were distributed as part of 
a seabed mapping exercise. This holding contains the four raster layers 
provided to all participants for the East of Haig Fras MCZ and the groundtruth 
samples. These four rasters are: Multibeam echosounder bathymetry, multibeam 
echosounder backscatter, modelled maximum current velocity at the seabed and 
modelled mean current velocity at the seabed. All rasters are in UTM29N 
projection at a 2 m x 2 m resolution. The groundtruth samples were derived 
from drop camera still images of rock substrate and sediment substrate samples 
were derived from grabs classified using Particle Size Analysis. Groundtruth 
samples contain the field "Test". Test values of 0 were used to train the 
models and values of 1 were withheld from all analysts as an independent test 
set.</dc:description>
