Dataset was created to update the extents of mangrove from the 2007 baseline established. It was first digitised using the 2014 aerial imagery and then those general locations were verfiied with the 2007 baseline, confirmation then occured with the 1m DEM derived from the 2014 National Lidar survey and cross-validated with a radiometric analysis, using the specific signature of mangroves.
