Terrain scan

The volcano was shrouded in cloud for the majority of the field trip, providing the perfect test conditions for AVTIS.

Below there is an example slice of radar data taken across the flanks of Lower Gages and the flow deposit fan. Strength of return signal ranges from low (blue) through to high (red)

Notice how the reflected signal strength differs depending upon the type of terrain being imaged: the trees give a weaker response than the bare rockface which is in turn different from the pyroclastic flow.  Ultimately this sort of radar data could be used to help characterise the terrain conditions as well as simply measuring the topography.
