Description

This GIS dataset portrays the distribution of glacial landforms in Alberta, based on the compilation of existing government survey mapping and research literature, supplemented by new analysis of remote sensing data. It is the dataset that was used to create Alberta Geological Survey Map 604 (Glacial Landforms of Alberta) using an intermediate step of reducing the density of closely spaced line segments to make the features suitable for map production at 1:1 000 000 scale. This dataset contains the original line features without any cartographic generalization. The data were created in geodatabase format and output for public distribution in shapefile format.

Description

This GIS dataset depicts the Foothills Erratics Train in Southwestern Alberta, Canada (GIS data, point features). The erratics train is composed of a distinctive type of glacially transported erratic, whose distribution might relate to coalescence of the Laurentide and Cordilleran Ice Sheets. These data were compiled from published sources. no attempt was made to verify their accuracy. These data comprise the point features to accompany Alberta Geological Survey Map 604, Glacial Landforms of Alberta, Canada. The data were created in geodatabase format and output for public distribution in shapefile format.

Description

This GIS dataset depicts a geostatistical model of the thickness of sediment overlying bedrock in Alberta. The sediment thickness surface was generated to assist the construction of a new geological framework for Alberta. The surface was derived by subtracting the bedrock topography of Alberta (Alberta Geological Survey Map 550) from the 60 m Shuttle Radar Topography Mission digital elevation model. These data comprise the raster surface of Alberta Geological Survey Map 551, Thickness of Quaternary and Neogene Sediment in Alberta, Canada.

Surficial Geology of the Calgary-Lethbridge Corridor (GIS data, polygon features)

Description

This GIS dataset is a compilation of existing surficial map information for the Calgary-Lethbridge Corridor area tiled into one layer. It is suitable for presentation and use at 1:250 000 scale.... More ≫

Description

This GIS dataset is a compilation of existing surficial map information for the Calgary-Lethbridge Corridor area tiled into one layer. It is suitable for presentation and use at 1:250 000 scale. The dataset was prepared by appending existing GIS datasets into one layer with a standard attribute table. These datasets were then compared against surficial maps for which GIS data were unavailable. Lastly, polygon boundaries were modified to agree with the surface topography as represented by a digital elevation model (DEM) with a grid cell size of 25 metres. Data sources included published Alberta Geological Survey and Geological Survey of Canada maps and the Agricultural Regions of Alberta Soil Inventory Database Version 4.0. Legend information for each polygon was translated by the author into the standard schema. This dataset contains the polygon features of Alberta Geological Survey Map 579, Surficial Geology of the Calgary-Lethbridge Corridor, and has been exported in shapefile...

Description

This GIS dataset portrays the distribution of glacial landforms within the Calgary-Lethbridge Corridor area, based on the compilation of existing government survey mapping and research literature, supplemented by new analysis of remote sensing data. The original line features have been modified where necessary for map production at 1:250 000 scale. This dataset contains the line features of Alberta Geological Survey Map 579, Surficial Geology of the Calgary-Lethbridge Corridor, and has been exported in a shapefile format for public distribution.
