Description

The data represents the density of wetland habitat in the agricultural region of Alberta in 2002. Wetlands are depressional areas that are wet for a long enough period that the plant and animals living in them are adapted to, and often dependent on, living in wet conditions for at least part of their life cycle. In drier areas of the province, wetlands tend to be more intermittent, while in wetter areas, wetlands tend to be more persistent. Topography also affects the occurrence of wetlands. Hummocky landscapes allow for pooling of water in depressions, while landscapes with longer slopes (e.g. the foothills) generally have better defined surface drainage patterns. A wetland in influenced by the interaction between the wet area, the wetland margin and upland area.Wetlands provide important habitat for waterfowl and many other types of wildlife. Wetlands reduce the impact of flooding, provide erosion control, purify water by removing sediment and nutrients, and contribute to...

Surficial Geology of the Peerless Lake Area, Alberta (NTS 84B) (GIS data, point features)

Description

This GIS dataset depicts the surficial geology of the NTS map area 84B (point features). The 1:250 000 scale dataset was compiled from four published 1:100 000 scale maps (AGS maps 265, 266, 267... More ≫

Description

This GIS dataset depicts the surficial geology of the NTS map area 84B (point features). The 1:250 000 scale dataset was compiled from four published 1:100 000 scale maps (AGS maps 265, 266, 267 and 267). The aggregated data was generalized by thinning out features where too dense to be represented clearly. The process was overseen by the mapping geologist.The data are created in ArcInfo format and output for public distribution in Arc export (E00) and shapefile formats.

The 1:250 000 scale dataset was compiled from four published 1:100 000 scale maps (AGS maps 265, 266, 267 and 267). The aggregated data was generalized based on lithologic unit name. The process was overseen by the mapping geologist.The data are created in ArcInfo format and output for public distribution in Arc export (E00) and shapefile formats.
