emis_dist: Allocate emissions into spatial objects (street emis to grid)

In vein: Vehicular Emissions Inventories

Allocate emissions into spatial objects (street emis to grid)

Description

emis_dist allocates emissions proportionally to each feature. "Spatial" objects are converter to "sf" objects. Currently, 'LINESTRING' or 'MULTILINESTRING' supported. The emissions are distributed in each street.

Usage

emis_dist(gy, spobj, pro, osm, verbose = FALSE)

Arguments

gy	Numeric; a unique total (top-down)
spobj	A spatial dataframe of class "sp" or "sf". When class is "sp" it is transformed to "sf".
pro	Matrix or data-frame profiles, for instance, pc_profile.
osm	Numeric; vector of length 5, for instance, c(5, 3, 2, 1, 1). The first element covers 'motorway' and 'motorway_link. The second element covers 'trunk' and 'trunk_link'. The third element covers 'primary' and 'primary_link'. The fourth element covers 'secondary' and 'secondary_link'. The fifth element covers 'tertiary' and 'tertiary_link'.
verbose	Logical; to show more info.

Note

When spobj is a 'Spatial' object (class of sp), they are converted into 'sf'.

Examples

## Not run: 
data(net)
data(pc_profile)
po <- 1000
t1 <- emis_dist(gy = po, spobj = net)
head(t1)
sum(t1$gy)
#t1 <- emis_dist(gy = po, spobj = net, osm = c(5, 3, 2, 1, 1) )
t1 <- emis_dist(gy = po, spobj = net, pro = pc_profile)

## End(Not run)
