Temuco

The LIDAR system is housed in a transportable station located at the Transportable Integrated Geodetic Observatory (TIGO) Consortium, formed by the University of Concepcion, the Military Geographic Institute of Chile (IGM), and the Federal Agency for Cartography and Geodesy of Germany (BKG).

The system needs to be operated by one person and the roof is opened and not protected of rain.
