AbstractThis new predictive surficial geology map product represents the con version of Open Files 7108 and 7233 and their legends, using the Geological Survey of Canada's Surficial Data Model (SDM version 2.0) which can be found in Open File 7631. All geoscience knowledge and information from the predictive surficial geology maps derived from LANDSAT in Open Files 7108 and 7233 that conformed to the current SDM were maintained during the conversion process. The purpose of converting legacy map data to a common science language and common legend is to enable and facilitate the efficient digital compilation, interpretation, management and dissemination of geologic map in formation in a structured and consistent manner. This provides an effective knowledge management tool designed around a geo-database which can expand following the type of information to appear on new surficial geology maps.
Summary(Plain Language Summary, not published)
The map identifies predictive surficial materials and associated landforms left by the retreat of the last glaciers. The surficial geology is based on satellite imagery interpretation and limited fieldwork. This work provides new geological knowledge and improves our understanding of the distribution, nature and glacial history of surficial materials. It contributes to resource assessments and effective land use management.
