Calculate metrics based on manually generated data at point locations
Source:R/calc_manual.R
calc_manual.Rd
Calculate metrics from manually generated vector data, at specific point locations and buffer radii. Currently supports vector data of buildings (polygons), roads (lines), trees (points), shrubs (polygons), turf (polygons), natural vegetation (polygons), and water (polygons).
Usage
calc_manual(
vector,
name = NULL,
points,
buffer_sizes,
plant_species = "species",
building_levels = "levels",
road_lanes = "lanes"
)
Arguments
- vector
sf dataframe containing geometric features (points, polygons or lines) to be summarised. Coordinate reference system should be similar to
points
.- name
Specify either
"buildings"
,"roads"
,"trees"
,"shrubs'
,"turf"
,"natveg"
, or"water"
. Used to represent the type of data invector
, each to be processed differently.- points
Point locations (sf object) to calculate the metrics.
- buffer_sizes
Radius of circle (in mapunits) for each point location; metrics will be calculated within the buffer area.
- plant_species
Column name in
vector
for plant species names, if inputvector
is vegetation (i.e., argumentname=
"trees"
or"shrubs"
). Defaults to"species"
. Column data should be of type character.- building_levels
Column name in
vector
for the number of building levels, whenname="buildings"
. Defaults to"levels"
. Column data should be numeric.- road_lanes
Column name in
vector
for the number of lanes per road line, whenname="roads"
. Defaults to"lanes"
. Column data should be numeric.
