Bedrock Topography of Alberta (gridded data, ASCII format)

Bedrock Topography of Alberta (gridded data, ASCII format) 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 physiographic terrain elements of the bedrock surface across Alberta, and the data sources and geostatistical methods used to interpolate this surface. 2022-04-13 Government of Alberta AGS-Info@aer.ca Form DescriptorsNature and EnvironmentScience and Technology72e72l72m73d73e73l73m74d74e74l74m82g82h82i82j82n82o82p83a83b83c83d83e83f83g83h83i83j83k83l83m83n83o83p84a84b84c84d84e84f84g84h84i84j84k84l84m84n84o84palbertabedrockbedrock topographyburied valleyscanadageologygeoscientificinformationgis datanumerical modellingpreglacial drainagepreglacial topographystructuralsubsurfacethalwegsGovernment information Bedrock Topography of Alberta (gridded data, ASCII format) - (ASCII GRID)ASCII Grid https://static.ags.aer.ca/files/document/DIG/DIG_2016_0039.zip Bedrock Topography of Alberta (gridded data, ASCII format) - (HTML)HTML https://geodiscover.alberta.ca/geoportal/rest/metadata/item/e7f7b37fe49041319a75f96f53a81bde/html Bedrock Topography of Alberta (gridded data, ASCII format) - (XML)XML https://geodiscover.alberta.ca/geoportal/rest/metadata/item/e7f7b37fe49041319a75f96f53a81bde/xml Alberta GeoportalHTML https://open.alberta.ca/opendata/a0231a3d-b478-4a0b-99c8-f48a011b2906
