Interior-Exterior Contrasts of Concave Hulls Amplify Driving Effect of Climatic factors on Geospatial Animal Migratory Rhythm

The file "shp_point" contains the gps points of animals. The file "concave_hulls" contains the built concave hulls of the migratory animals. The explanation in the dryad-data.xlsx: year and moth are the monthly date, and numbered from 1 to 73 in the line num. x and y are the projected coordinate, while x1 and y1 are the coordinate under Geographic Coordinate System. pci, tci, and ndvi are the values of the Interior-Exterior contrasts of concave hulls. While _con represent the values of the Interior of concave hulls.
