Aquatic information and stream survey data collected
by Irving fisheries biologists is placed in the company’s GIS system.
This computer-generated mapping system compiles the information used
by Irving foresters to plan their forestry activity and protect critical
fish habitat like salmon spawning beds and holding pools. The GIS system
has access to a global positioning unit linked to a depth sounder. It
can provide accurate three dimensional lake profiles as part of the
GIS database.
