FathomDEM v1-0 Americas

FathomDEM Digital Elevation model for locations west of 30W (Americas and part of Oceania). FathomDEM is a global 30m DEM produced using a novel application of a hybrid vision transformer model. This model removes surface artifacts from a global radar DEM, Copernicus DEM, aligning it more closely with true topography. This dataset is documented in the peer reviewed article FathomDEM: an improved global terrain map using a hybrid visiontransformer model FathomDEM data for locations east of 30W is available in the dataset FathomDEM v1-0 Eurasia and AfricaFathomDEM：适用于30°西经以西区域（美洲及部分大洋洲）的数字高程模型（Digital Elevation Model，DEM）。 FathomDEM是一款全球尺度30米分辨率的数字高程模型，其构建采用了混合视觉Transformer（vision transformer）模型的创新应用方案。该模型可去除全球雷达数字高程模型——哥白尼数字高程模型（Copernicus DEM）——的表面伪影，使其更贴合真实地形地貌。 本数据集的相关研究已发表于同行评议论文《FathomDEM：基于混合视觉Transformer模型的改进型全球地形地图》。 30°西经以东区域的FathomDEM数据可在数据集《FathomDEM v1.0 欧亚与非洲》中获取。
