From the text ... 'The Société de Conservation de l*Outaouais, which protects 80 000 km2 southwestern Quebec timberland against fire, has been experimenting with lightning location systems, in an attempt to minimize the problem of lightning caused fires. The experiments, using equipment developed by Lightning Location and Protection Ltd. of Tucson, Ariz., have been carried out in close collaboration with the Petawawa National Forestry Institute and the Quebec Department of Energy and Resources. The first system was installed in 1980 and was composed of two lightning direction finders, a position analyzer, and an automatic plotter. In 1981 a third direction finder was added which improved the reliability and accuracy of the system. All cloud-to-ground lightning strokes are recorded and automatically mapped on the plotter. In this way the Societe is able to track the path, in real time, of any lightning storm occurring on or near the territory under its protection.'
