get_sep_dist_calpost_grd: Calculate separation distances

In maxbre/rcalpuff: R functions for CALPUFF

Calculate separation distances

Description

Get a a simple feature data frame of separation distances from the source (origin) point to some predefined concentration contour lines

Usage

get_sep_dist_calpost_grd(
  file_grd,
  epsg = 32632,
  x_source,
  y_source,
  levels = NULL,
  degree_step = 5,
  trans_factor = 1
)

Arguments

file_grd	string path to the CALPOST grid file
epsg	number epsg to set crs in the raster object
x_source	x coordinates of the source (origin) point
y_source	y coordinates of the source (origin) point
levels	vector of defined levels for the contour lines
degree_step	angle degree to scan directions where calculate distances from source (origin) point
trans_factor	number, transformation factor to be applied to calculated values, leave it as default = 1

Value

a simple feature data frame
