lidar_point_value: Extract point value from LiDAR raw raster tables (20x20m)

In MalditoBarbudo/lfcdata: Access to the LFC Databases

Extract point value from LiDAR raw raster tables (20x20m)

Description

lidar_point_value is a wrapper for the $point_value method of lfcLiDAR objects. See lidar.

Usage

lidar_point_value(object, sf, point_id_variable, variables)

Arguments

object	lfcLiDAR object, as created by lidar
sf	sf object with the points to extract
point_id_variable	character vector of length 1 with the name of the variable of sf that contains the point identificator (name, code...)
variables	character vector with the names of the variables to access

Value

This function returns the same sf object provided, with new columns with the values of each point for each variable requested.

Examples

if (interactive()) {
library(dplyr)
lidardb <- lidar()

points_data <-
  nfi()$get_data('plots', spatial = TRUE) |>
  dplyr::slice(1:5) |>
  dplyr::select(plot_id)

dbh_plots <- lidar_point_value(lidardb, points_data, 'plot_id', 'DBH')

# lidardb is an R6 object, so the previous example is the same as:
lidardb$point_value(points_data, 'plot_id', 'DBH')
}
