to_munich: Export emissions to Model of Urban Network of Intersecting Canyons and Highways (MUNICH)

Description

to_munich Export spatial emissions objects according the format required by MUNICH. This function was designed to read street emissions from VEIN by it can be used to read any other.

Usage

to_munich(sdf, idbrin, typo, width, height, crs = 4326)

Arguments

sdf

Street Emissions object class 'sf' LINESTRING or "SpatialLinesdataFrame". The columns are the emissions.

idbrin

Integer; id.

typo

Integer; id2.

width

Integer; width.

height

Integer; heigth.

crs

Numeric; Coordenade Reference System with default value of 4326.

Value

A list with a data frame with columns "i", "idbrin", "typo", "xa", "ya", "xb", "yb" and the pollutants; and another data.frame with "i", "length" (m), "width" (with value 0) and "height" (with value 0). Width and height must be obtained by the user.
