is_prepared_tile: Check whether a LAS tile object has been prepared

In mbedward/CERMBlidar: A collection of functions to process aerial LIDAR data

Check whether a LAS tile object has been prepared

Description

When a LAS tile is imported using the prepare_tile function, point heights are normalized relative to ground elevation and flight lines are identified. This results in two extra columns (Zref and flightlineID) being added to the LAS data table. This function checks that these two columns are present. It also checks that the tile has point data, returning FALSE if the point cloud is empty.

Usage

is_prepared_tile(las)

Arguments

las	A LAS object, e.g. imported using prepare_tile.

Value

TRUE if the tile has been prepared or FALSE otherwise.
