100th degree overpass data

Data shared by David Kroodsma of Global Fishing Watch on June 26, 2024. Data produced by Paolo, F.S., Kroodsma, D., Raynor, J. et al. Satellite mapping reveals extensive industrial activity at sea. Nature 625, 85–91 (2024). https://doi.org/10.1038/s41586-023-06825-8. Data used in replication package of "Deterring Industrial Vessels from African Coastal Fisheries" by Aishwarya Agarwal and Gabriel Englander. Each file in the folder is a year-month of overpass rasters at 100th of a degree for Africa (bounding box: lat_min = -39, lat_max = 39, lon_min = -29, lon_max = 57). Overpasses is the sum of Sentinel-2 satellite overpasses for the grid cell. lon_index = floor(lon*100) and lat_index = floor(lat*100). This means dividing lon_index and lat_index by 100 gives the lower left corner of the 100th degree grid cell.
