Abstract: SeafloorMapper is a GUI-based application designed for identification of seafloor photons with ICESat-2 ATL03 data. The software integrates two mapping modes, manual and automatic, and three workflows for generating datasets in different formats according to users' needs. Workflow tools include data pre-processing, manual and automated seafloor photon identification, manual post-processing, and creation of training data for the AI model used for automated seafloor photon identification. We demonstrate the software with two case studies, one conducted in Cambridge Bay, Canada, where seafloor depths obtained from ATL03 data using SeafloorMapper were compared against survey data from the Canadian Hydrographic Service, and another conducted at Sanikiluaq, Canada, where seafloor depths derived from ICESat-2, in the absence of other bathymetric information, were used to produce satellite-derived bathymetry for the area. SeafloorMapper is a useful and robust tool to extract bathymetric information from ATL03 data. [ABSTRACT FROM AUTHOR]
