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.文件"shp_point"存储有动物的GPS（全球定位系统）点位。 文件"concave_hulls"存储有迁徙动物的已构建的凹包（concave hull）。 dryad-data.xlsx 中的说明如下：year与moth（原文疑似为month笔误）为月度日期，按行号从1至73依次编号。x与y为投影坐标系（Projected Coordinate System）下的坐标，x1与y1则为地理坐标系（Geographic Coordinate System）下的坐标。pci、tci及ndvi为凹包的内外对比度（Interior-Exterior contrasts）数值；_con代表凹包内部区域的对应数值。
