Last updated
Returns metadata for one or more las
or laz
point cloud/LiDAR files from a local file or directory source, optionally constraining the bounding box for metadata retrieved to the lon/lat bounding box specified by the x_min
, x_max
, y_min
, y_max
arguments.
Note: specified path must be contained in global allowed-import-paths
, otherwise an error will be returned.
