ReadMe for The geography of spatial synchrony, Walter, Jonathan A, Sheppard, Lawrence W, Anderson, Thomas L, Kastens, Jude H, Bjornstad, Ottar N, Liebhold, Andrew M, Reuman, Daniel C 2017-04-26 This readme file describes a gypsy moth defoliation dataset accompanying the above publication. For any further inquiries please contact jonathan.walter@ku.edu or reuman@ku.edu The file "gypsy_moth_defoliation.csv" contains area defoliated (in units of square kilometers) by the gypsy moth from 1975 to 2014 in 64 x 64 km grid cells spanning the area considered "generally infested" by the gypsy moth (i.e., where gypsy moth populations were established) as of 1975. Defoliated area is based on aerial surveys. Column headings are as follows: 1) X: the X coordinate of the grid cell centroid (projection information listed at the bottom of this document) 2) Y: the Y coordinate of the grid cell centroid 3-42) 1975-2014: gypsy moth defoliation recorded in a given year Projection information: Projected coordinate system: Albers False easting: 0 False northing: 0 Central meridian: -85 Standard parallel 1: 34 Standard parallel 2: 47 Latitude of origin: 0 Linear unit: Meter Geographic coordinate system: WGS 1984
