detect_basin: Find out the gridcells in the basin controled by the station.

In Sibada/sibadaR: Sibada's accumulated R scripts for next probably use to avoid reinventing the wheel.

Description

Offer the grid of flow direction and the site (row and column) of the hydrological station and returns a table of the coordinates of the gridcells in the basin controled by the station.

Usage

detect_basin(dir, stn_col, stn_row, arc_code = TRUE, xcor = NULL,
  ycor = NULL, csize = NULL, get_coords = FALSE)

Arguments

dir	Direction grid created by create_flow_direction() or a matrix.
stn_col	Column of the hydrological station
stn_row	Row of the hydrological station
arc_code	If use the ArcInfo direction code. Default True.
xcor	X coordinate of the corner of the grid. Should offered if dir is a matrix.
ycor	Y coordinate of the corner of the grid. Should offered if dir is a matrix.
csize	Size of the gridcells. Should offered if dir is a matrix.
get_coords	If return the coordinates of the gridcells of the basin, or return the rows and columns.

Value

A data frame contains the coordinates of the gridcells in the basin.
