AbstractThis release provides digital data related to the identification and display of glacial landforms across Canada using remotely sensed and digital topographic data. The work provides a national-scale map of ice-sheet flowlines and flow tracts derived from landform indicators based on original observations from the remotely sensed data. The data were collected under the Remote Predictive Mapping (RPM) project of the Geological Survey of Canada, with funding also from NSERC, and aims to contribute to remote predictive mapping by using multi-scaled digital data to analyze and interpret existing and new geological data within an evolving predictive landscape framework.
The Flowline Map on this DVD shows directional flow patterns for the Laurentide and Cordilleran ice sheets for Canada south of 75° N. by depicting glacial landforms, flow indicators, flowlines and flow tracts using SRTM (Shuttle Radar Topography Mission) and LANDSAT 7 Enhanced Thematic Mapper + data. Glacial landforms, best seen at scales ~1:100,000 (LANDSAT 30 m resolution) and ~1:250,000 (SRTM 90 m resolution) include: drumlins, flutings, rises, eskers, de Geer moraines, hummocky terrain, Rogen terrain, end moraines, and sinuous ridges. All landforms are presented in digital form and shown on a pdf map at a scale of 1:5 million. Additional LANDSAT ETM+, and thematic layers are included to help the user appreciate the context of landform analysis and interpretation. The data with readily accessible formats that allow maximum and uncomplicated use are expected to serve as aids for detailed mapping, mineral exploration, and mineral potential assessment and for other studies. As well, users may integrate and assess this data with their own data. Descriptive notes explain how landforms were mapped and grouped into regional flow patterns.
