Gerard France F. pub A900 C180 2023sub_E_C_M_P Data provided are monthly surface water layers extracted from Sentinel1A SAR data for 3 districts in India (Shivamogga, Sindhudurg, Wayanad) for the year 2017 and 2018. Surface water body layers were mapped using an average monthly threshold value extracted from the image backscatter histogram. The average threshold value excluded the monsoon months due to the difference in water and not water area. The threshold value was slightly lesser than the mean threshold value. The end product was validated using field data which resulted in user and producer accuracies. Monthly surface water body layers were not produced for a few months due to the non-availability of Sentinel 1 data. 2022-02-15 published NERC EDS Environmental Information Data Centre https://catalogue.ceh.ac.uk/documents/3c23fea1-5b27-4b01-b9ef-fc13346cfedc dataset MR/P024335/1 Medical Research Council http://dx.doi.org/10.13039/501100000265 MR/P024335/1 Arts and Humanities Research Council http://dx.doi.org/10.13039/501100000267 MR/P024335/1 Biotechnology and Biological Sciences Research Council http://dx.doi.org/10.13039/501100000268 MR/P024335/1 Engineering and Physical Sciences Research Council http://dx.doi.org/10.13039/501100000266 MR/P024335/1 Natural Environment Research Council http://dx.doi.org/10.13039/501100000270 NE/R000131/1 Natural Environment Research Council http://dx.doi.org/10.13039/501100000270 rdmsupport@lancashire.ac.uk Student Samrat Abhishek ASamrat@uclan.ac.uk ds_ext https://doi.org/10.5285/3c23fea1-5b27-4b01-b9ef-fc13346cfedc pub https://clok.uclan.ac.uk/54282 2017 2018
