Abstract
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. During the initial stages of planning the need for primary landscape data became apparent. For example, existing surficial geology map coverage is at a scale of 1:250 000 and not sufficient for regional land-use planning. A project to remotely predict surficial materials was initiated by the Ontario Geological Survey in response to this information need. Remotely sensed imagery which is available at various resolutions and degrees of coverage, and existing digital elevation models (DEMs) can be used as proxies for the landscape. Combining information gained from the imagery, such as vegetation type and moisture conditions, with landform recognition from DEMs, various landform/sediment and vegetation cover/material relationships can be determined and applied to remotely predict surficial material distribution. Object based image analysis is being used in the processing of imagery and DEM data. On-screen digitization of select landforms supplements the predicted material distribution and will occur as symbols on the maps. Ground verification is based on data collected during previous field programs and a modest amount of field work. Key aspects of the field work include making observations of landform/sediment relations, observations of the associated vegetation communities and attempting to understand the spatial and stratigraphic relationships between materials. The understanding of these associations is vital to the project’s goal of remotely predicting surficial materials and producing maps of these in the Far North of Ontario.
