  abstract = {{T}he characterization of estuarine hydrodynamics primarily depends on knowledge of the bathymetry and topography. {H}ere, we present the first comprehensive, high-resolution dataset of the topography and bathymetry of the {A}mazon {R}iver estuary, the world's largest estuary. {O}ur product is based on an innovative approach combining spaceborne remote sensing data, an extensive and processed river depth dataset, and auxiliary data. {O}ur goal with this mapping is to promote the database usage in studies that require this information, such as hydrodynamic modeling or geomorphological assessments. {O}ur twofold approach considered 500 000 sounding points digitized from 19 nautical charts for bathymetry estimation, in conjunction with a state-of-the-art topographic dataset based on remote sensing, encompassing intertidal flats, riverbanks, and adjacent floodplains. {F}inally, our estimate can be accessed in a unified 30 m resolution regular grid referenced to the {E}arth {G}ravitational {M}odel 2008 ({EGM}08), complemented both landward and seaward by land ({M}ulti-{E}rror-{R}emoved {I}mproved-{T}errain digital elevation model, {MERIT} {DEM}) and ocean ({G}eneral {B}athymetric {C}hart of the {O}ceans version 2020, {GEBCO}_2020) topographic data. {E}xtensive validation against independent and spatially distributed data, from an airborne lidar survey, from {ICES}at-2 altimetric satellite data, and from various in situ surveys, shows a typical vertical accuracy of 7.2m (riverbed) and 1.2 m (non-vegetated intertidal floodplains). {T}he dataset is available at https://doi.org/10.17632/3g6b5ynrdb.2 ({F}assoni-{A}ndrade et al., 2021).},
