[CANUFNET] tree protection

[Julian Dunster via CANUFNET]

Many of arborists in Britain regularly use GPS, GIS, and CAD routinely 
for development projects. One of them developed special CAD software for 
the purpose. The lack of its use in Canada almost certainly reflects a 
lack it being taught in curricula, as part of professional practice. We 
still focus on pruning, planting, fertilising and tree stuff, all of 
which is fine but needs expanding to the 21st century to include 
effective use of technology. Several of my colleagues in BC use CAD all 
the time. I use GPS and GIS.

We need to expand the horizon of what arboriculture and urban forestry 
might / should entail. At the same time we can also inform surveyors and 
architects of we expect them to produce - such as CAD symbols for canopy 
that are scaled to reality on the ground, not simply rubber stamped on a 
plan, all at the same size (a pet peeve).
