Download raw LIDAR data

Description

Check if raw LIDAR data are available at the shape location. The raw LIDAR data are not classified; they correspond to a cloud point.

Usage

get_raw_lidar(x, destfile = ".", grid_path = ".", quiet = F)

Arguments

x	Object of class sf or sfc. Needs to be located in France.
destfile	Folder path where data are downloaded. By default set to "." e.g. the current directory
grid_path	Folder path where grid is downloaded. By default set to "." e.g. the current directory
quiet	if TRUE download is silent

Details

get_raw_lidar() first download a grid containing the name of LIDAR tiles which is then intersected with x to determine which ones will be uploaded. The grid is downloaded to grid_path and lidar data to destfile. For both directory, function check if grid or data already exist to avoid re-downloading them.

Value

No object.
