aggregate_ncdf: Aggregate ncdf climate (raster) data for catchment subbasins

In chrisschuerz/aRastoCAT: a Raster Climate data Aggregation Tool

Description

Aggregate ncdf climate (raster) data for catchment subbasins

Usage

aggregate_ncdf(
  ncdf_file,
  crs_ncdf,
  shape_file,
  shape_index,
  var_name = NULL,
  latlon_name = NULL,
  time_range = NULL
)

Arguments

ncdf_file	Path to the ncdf file
crs_ncdf	Character string providing the reference system of ncdf file
shape_file	Shape file with the basin sub-unit polygons or path to the file as character string
shape_index	Name of the column in the basin shapefile attribute table that provides the indices of the basin subunits
var_name	(optional) character string. Name of the variable array to be extracted from the ncdf file. If NULL the first variable provided in the ncdf file is selected automatically
latlon_name	(optional) character vector of length 2. Names of the longitude and latitude variables in the ncdf file. Must be provided if the variables connot be found automatically
time_label	(optional) vector of length 2. Start and end date of the time range that should be extracted from the ncdf file. Dates can be either provided as unambiguous text strings (e.g. 'yyyy-mm-dd' or in a date format

Value

Returns a tibble that provides the time series of the aggregated variable for the respective basin subunits
