About the datasets: it includes a shapefile with the outline of the 613 Meteorite Stranding Zones (Fig. 7, "613MSZs.zip"), the observations used for classification, and the continent-wide probability to find meteorites (at 450-meter resolution, Fig. 5, "positive_classified.nc"). References to the literature are provided in the corresponding publication. Meteorite locations are based on the Meteoritical Bulletin Database (available at https://www.lpi.usra.edu/meteor/). - bias_above200m1kmbuff_expanded_dissolved: shapefile of polygons of unlabelled observations - meteorite_locations_raw.csv: contains locations of meteorite finds as defined in the meteoritical bulletin consulted on 05/07/2019 - meteorite_types.csv: contains meteorite names and types as defined in the meteoritical bulletin consulted on 05/07/2019 - validation_neg.csv: contains locations of negative observations used for validation - TEST_neg.csv: contains locations of negative test observations - TEST_pos.csv: contains locations of positive test obesrvations - MSZs_ranked: shapefile of ranked meteorite stranding zones - Test_neg4326: shapefile of locations used as negative test data - Cal_neg4326: shapefile of locations used as negative calibration/validation data - TestMSZs_pos4326: shapefile of locations used as positive test data in MSZ-level assesment - 613MSZs: shapefile of outlines of meteorite stranding zones - positive_classified.nc: netcdf of positive classified observations with their estimated a posteriori probabilities
