Description

The bedrock topography of Alberta is the surface of the top of Upper Cretaceous and Paleogene bedrock, and reveals geomorphic features created by Paleogene to Recent river systems and Quaternary glaciation. This grid is a computer-generated geostatistical model of the bedrock topography of Alberta using previously published information from Alberta Geological Survey (AGS) maps and reports, as well as new data. The quality of this data has been assessed and then a quality-weighting approach was applied to the dataset prior to interpolation. The surface was modelled using a 500m x 500m grid cell spacing, and as such should not be used for local scale studies. This grid represents the surface portrayed in AGS Map 602, Bedrock Topography of Alberta, and this grid will continue to be updated as part of the Alberta Geological Framework project. Explanatory notes, references, and data sources appear on a supplementary page to accompany Map 602. These notes describe the distribution of...

Description

This GIS dataset depicts the result of a geostatistical model of the bedrock topography in Alberta. This model is based on water-well litholog data, stratigraphic picks made on oil and gas petrophysical logs, data derived from digitized contour interpretations on bedrock topography maps, including bedrock outcrop locations and the 60 m grid-spaced Shuttle Rader Topography Mission digital elevation model. These data comprise the raster surface of Alberta Geological Survey Map 550, Bedrock Topography of Alberta, Canada.

Description

A digital grid of the top of the Empress Formation where present, or the topography of the surrounding landscape, where the formation is absent. This includes the units 1 to 3 of the Empress Formation in buried valleys, as well as undifferentiated Empress interfluve sediments resting on the bedrock surface between buried valleys. The unit is originally modelled from borehole data and adjusted to the bedrock surface, the surfaces of units 1, 2, 3 and interfluve units of the Empress Formation, and the present-day land surface. The grid is generated at a 250 metre cell-size resolution, based on 2003 information.

Description

A digital grid of the subcrop edge of the Second White Specks Formation and bedrock units above, such as the Wapiti Formatioin, originally modeled from borehole data and adjusted to present-day and paleo river erosion. Values in the grid correspond to areas where the unit is present, or where it is absent (denoted by the null value '-9999'). The grid is generated at a 250 m cell-size resolution, based on information as recent as 2003.
