Delta-X: UAVSAR L3 Gridded Open Water Channels, MRD, LA, USA, 2021, V2

This dataset provides gridded estimates of water channels for the Atchafalaya and Terrebonne basins of the Mississippi River Delta in Louisiana, U.S.A. The data show channels with open water that are as narrow as 10 m. These channel estimates were generated from the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) Level 1B interferometric products in radar coordinates acquired in the Spring and Fall Delta-X deployments of 2021, which have a spatial resolution of approximately 6 m. UAVSAR is a polarimetric L-band synthetic aperture radar (SAR) flown on the NASA Gulfstream-III aircraft. The data are provided in cloud-optimized GeoTIFF format. The channel estimates can be used to define open water paths in hydrodynamic models and to evaluate model performance.

本数据集提供了美国路易斯安那州密西西比河三角洲阿切法拉亚和特雷博恩流域的水道网格估计值。数据展示了宽度仅为10米的开放水域水道。这些水道估计值由无人驾驶飞行器合成孔径雷达（UAVSAR）Level 1B干涉测量产品生成，该产品采用雷达坐标，在2021年春季和秋季的Delta-X部署中获取，空间分辨率为大约6米。UAVSAR是一种极化L波段合成孔径雷达（SAR），搭载于美国宇航局Gulfstream-III飞机上。数据以云优化GeoTIFF格式提供。水道估计值可用于定义水动力模型中的开放水域路径，并评估模型性能。
