1980 Forest Inventory Mapping
The
1980/82 Forest Biomass inventory was carried out during the period 1980-1982.
The mapping was done based on aerial photography taken at a scale of 1/10,000
during the summer of 1980. Both black and white and false colour infrared
imagery were used. The photo interpretation and mapping was carried out by
Dendron Resources of Ottawa.
The
stand delineation was done on the black and white photographs and the
attributes were added to the photographs. The interpreted stand/polygon
boundaries were transferred to mylar and the polygon attributes added. A
database was created using primarily the photo interpretation. Other location
information was added such as county, forest management district, etc.
The
base maps used for this project were created from the 1970 orthophoto maps as
used by property assessment. These maps were photographically reduced from the
1/5,000 to 1/10,000 and assembled to produce 1/10,000 scale maps with a three
by six minute map window. (This map window was also used in the 1990 inventory
and when the new base maps were created by L.R.I.S. based on 1985 and 1988
imagery.)
