FabDEM correction with ICESat-2 and ANN for 2D hydraulic modelling in floodplain areas

The datasets includes processed ICESat-2 ATL03 processed elevation data, together with Sentinel-2 MSI bands (B2, B3, B4 and B8) that are used in a ANN training to correct FabDEM. Additionally, examples of flood inundation maps are included, for simulations using FabDEM and the corrected ANN DEM. The inundations maps are compared with observed data to assess their performance. The data covers a 50 km floodplain in the Upstream Yellow River本数据集包含经处理的ICESat-2 ATL03高程数据，配套涵盖哨兵2号多光谱成像仪（Sentinel-2 MSI）的B2、B3、B4及B8波段数据，上述数据用于人工神经网络（Artificial Neural Network, ANN）训练以校正FabDEM。此外，数据集还涵盖利用FabDEM与经人工神经网络校正的数字高程模型（ANN DEM）开展洪水淹没模拟所得到的示例淹没范围图。我们将此类淹没范围图与实测洪水观测数据进行比对，以评估两款模型的模拟性能。该数据集覆盖黄河上游一处长度为50公里的河漫滩区域。
