This function make an interpolation whith the trend surface method where the user have to inform the polynome degree. The interpolation is made over the tageded points for all the serie on the input.
Arguments
- my_folder
Folder containing the ts input files.
- bassin_limit_path
A shapefile containing the bassin limit where the trend suface function have to be predicted.
- poly_degree
The degree to be used in the polynomial function for the trend surface.
- resolution
The resolution for the output raster in degree.
Examples
ts_to_area(
my_folder = system.file("extdata/ts_input", package = "wcswatin"),
bassin_limit_path = system.file("extdata/sl_bassin/sl_bassin_limit.shp",
package = "wcswatin"
),
poly_degree = 2,
resolution = 0.5
)
