#This script uses the worklfow code applied to the Oregon case study. Daily methods (GAM,GWR, Kriging) are tested with
|
4 |
|
|
#different covariates using two baselines. Accuracy methods are added in the the function script to evaluate results.
|
5 |
|
|
#Figures, tables and data for the contribution of covariate paper are also produced in the script.
