get_lidar: get_lidar

Description

Search for and download LiDAR data based on coordinates of a spatial point with a given distance or a bounding box. The maximum distance is 1000m. Different dataset could be found and the function automatically downloads the latest dataset. To get more details of data on a larger scale, please use viewscape::lidar_search.

Usage

get_lidar(
  x,
  y,
  r,
  epsg,
  bbox,
  max_return = 1000,
  folder = NULL,
  iftest = FALSE
)

Value

lidR LAS object.

Arguments

x: numeric, indicating Longtitude degree of the center point.
y: numeric, indicating latitude degree of the center point.
r: numeric, indicating search distance for LiDAR data. The maximum distance is 1000m (3281ft). If r > 1000m, it will be reset to 1000m.
epsg: numeric, the EPSG code specifying the coordinate reference system.
bbox: vector, a bounding box defining the geographical area for downloading data.
max_return: numeric, indicating the maximum of returns.
folder: string (optional), indicating a path for downloading the LiDAR data
iftest: logical, if true, run this in the test mode.
