* The teaching licence allows installation of the software on an unlimited number of workstations destined for student use of TerraSys, with the reserve that these stations are situated within the same physical site (defined by the civic address of the institution). In the case where an institution wishes to install the software on a number of workstations at different sites, it must obtain a distinct licence for each site. No copy of the program may be made by the students and no commercial usage of the software is authorised. It is the responsibility of the licence holder to ensure the respect of these conditions.
