Mangrove Extent maps for the Klang Islands, Malaysia

Mangrove Extent maps for the Klang Islands, Malaysia Satellite derived maps of mangrove extent in the Klang Islands, Malaysia for use within a GIS. Using the 2010 Global Mangrove Watch (GMW) map downloaded from https://data.unep-wcmc.org/datasets/45 as a baseline, a refined local area product was generated by manually editing the GMW polygons in QGIS to match satellite data from 2010. This refined map was then used as a baseline and manually edited to reflect changes when comparing to satellite data for a given year. The output is a map of mangrove extent for each year. Due to the difficulty in obtaining cloud free satellite data for the entire area multiple scenes were used for many years. Data are supplied as polygons in ESRI shapefile format with a separate shapefile for each year.
