Sinopsis
As part of a geography course, students learn to do topographical surveys. A stroll at the Champlain lookout, in the Outaouais region, will allow them to familiarize themselves with the different methods in use from Samuel de Champlain to the present day. Finally, a visit to the Directorate of Energy, Mines and Resources Canada, in Ottawa, will introduce them to a new device capable of automatically drawing contour lines. This film describes this new technique of digital mapping and gives us an overview of the progress it brings in this field.
