A high spatial resolution coastal wetland map of the Bohai rim

I developed a workflow for rapidly mapping coastal wetlands at high spatial resolution, using the recently developed Google Earth Engine cloud platform, machine learning algorithm, open-access Synthetic Aperture Radar and optical images from the Sentinel satellites, and topographic indexes. Based on the method, I derived a coastal wetland map of the Bohai rim (BRCW10) during 2018-2019. It has a a spatial resolution of 10 m, and producer accuracy of 82% according to validation using 150 wetland samples. Here, I share the BRCW10 data and several auxiliary data including normalized difference vegetation index (NDVI) and normalized difference water index (NDWI).<br>New coastal line data was used in the version 2 data.
