Description
Summary:This dataset consists of a Very High Resolution water body delineation dataset computed with the HLWATER V1.0 model (Freitas et al., 2024) over PlanetScope-Dove imagery (3-m spatial resolution) for Western Nunavik (Eastern Hudson Bay), Subarctic Canada. It covers a total area of 41,832 km2 within the latitudes 54° to 58° N and the longitudes 74° to 78° W. The dataset is composed of 335,281 water bodies. Additionally, 1 km2 hexagonal grids are provided with the calculation of the limnicity (water fraction of land surface) and limnodensity (density of water bodies considering their centroids). Outputs are provided in shapefile and geodatabase formats. The manuscript detailing these outputs has been submitted to GIScience and Remote Sensing. ...
