Ontario 1981-1985


General Methods
Sampling & coverage of blocks

Ontario was divided into 100km x 100km blocks, each of which was further divided into 100 10km x 10km squares. The southern half of the province was sampled and mapped at the block level, while the northern half was sampled at the block level but mapped at the square level.

Coordination of coverage
Management of this project was accomplished with the help of coordinators in 46 regions. See the List of Coordinators on the project site.
