Limited helicopter-supported field work combined with the examination of
archival information (Riley and Boissonneau (unpublished field notes and
photographs); Geological Survey of Canada, Operation Winisk
unpublished field notes; Skinner 1973; Sanford, Norris and Bostock 1968;
Sanford and Norris 1975; and Thorleifson, Wyatt and Warman 1993, and
their unpublished field notes) provided the ground control on the
classification of objects. In addition, information from the various other
Far North Information Knowledge Management Program projects, such
as base data and land cover information (Ontario Ministry of Natural
Resources, in progress), has been used in the interpretation and
classification of the surficial materials.
The maps show only the surface material distribution. For better definition
of wetland types please refer to the Ontario Ministry of Natural Resources
Far North Land Cover 2005–2009 digital series of maps. Older deposits
that occur along many of the deeply incised river valleys are not depicted.
However, the reader is encouraged to review books by Skinner (1973)
and Thorleifson, Wyatt and Warman (1993) for further information and
details on the older sediments exposed along rivers within the Hudson
Bay Lowland.

SPOT imagery (4 colour bands and the panchromatic band), a digital
elevation model and its derivatives and the Ontario Hydro Network vector
drainage shape files (Ontario Ministry of Natural Resources 2010) are the
primary data sources for this remote predictive mapping exercise. A
multiresolution segmentation algorithm, using different image layer
weights, scale parameters and homogeneity criterion, within an objectbased image analysis software is used to achieve meaningful objects
representing various surficial material types. Objects are then classified
based on digital signature, internal variability of signature and proximity
to certain vector layers and certain adjacent material types.

In 2008, the Ontario government announced plans to permanently protect
half of the Far North region of Ontario and launched a planning process
to support this goal (Far North Information Knowledge Management
Program). During the initial stages of planning, the need for primary
landscape data became apparent. A terrain mapping project to remotely
predict surficial materials was initiated by the Ontario Geological Survey
in response to this information need.
