The datasets shows the spatial coastal baseline which is split into 'frontages'. These are defined as lengths of coast with consistent characteristics based on the cliff behaviour characteristics and the defence characteristics. It is intended as a benchmark dataset showing erosion extents and rates for three periods:
- Short Term (0 - 20 yr)
- Medium Term (20 - 50 yr) and
- Long Term (50 - 100 yr).
Defence type and Shoreline Management Plan (SMP) policies for each of the three periods described above are included.
