Spatial Distribution Points of Major Coastal Aquaculture Zones in China (2022)

The original dataset, created using deep learning methods, extracted the polygon vector boundaries of raft and cage aquaculture zones in offshore China from high-resolution (HSR) remote sensing imagery.To facilitate rapid analysis and visualization, this dataset provides the geometric centroids of aquaculture polygons from the original dataset that have an area greater than 1200 square meters.

Each centroid is a single data record, with attribute information that includes the area of the original polygon and its type: Raft (label: 1) or Cage (label: 2). The dataset is provided in the GeoPackage (.gpkg) format and serves as crucial data support for research in marine spatial planning, aquaculture capacity assessment, and marine ecological environment monitoring.Please contact the author to obtain the complete RCdata_2022_2m dataset.Related Paper：Chen, Y., He, G., Yin, R., Wang, G., & Peng, X.
