This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of hydrostratigraphic unit (HSU) C1, which contains fine-grained materials underlying coarse-grained sediments of HSU S2 in the Neogene-Quaternary succession of the Sylvan Lake sub-basin. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of steps taken to produce the structure grid.

The dataset shows the distribution and spatial extent of the 3D models that were created in the context of Canadian aquifers mapping projects from the Geological Survey of Canada.

This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of the Lea Park Formation in the Sylvan Lake sub-basin. Bedrock units included in the Sylvan Lake sub-basin model are derived from the Geological Framework of Alberta, a regional geological model of the province. The Top of Lea Park Formation, provided by the Geological Framework of Alberta, was clipped to the Sylvan Lake sub-basin model domain for integration into a multi-layer hydrostratigraphic model. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of the methodology used to produce this grid.

The numerical canopy model (MNC) is a representation of the altitude of the canopy. This 3D representation of the arboreal vegetation corresponds to the 2015 2D canopy.If necessary, the MNC can be coupled with the [Numerical Surface Model (MNS)] (/city-of-montreal/numeric-surface-model) 2015 in order to obtain more detailed coverage.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of hydrostratigraphic unit (HSU) S1, which contains coarse-grained material lying directly on bedrock and constrained to paleovalleys in the Neogene-Quaternary succession of the Sylvan Lake sub-basin. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of steps taken to produce the structure grid.

To support improved groundwater geoscience knowledge for southern Ontario, a regional 3-D model of the surficial geology of southern Ontario has been developed as a part of a collaboration between the Ontario Geological Survey and the Geological Survey of Canada. Covering approximately 66,870 km2 in area, the model is a synthesis of existing geological models, surficial geology mapping, and subsurface data. The model is a simplified 9-layer reclassification of numerous mapped local surficial sediment formations in places over 200 m thick with a total volume of approximately 2,455 km3. The model integrates 1:50,000 scale surficial geology mapping with 90 m bathymetrically corrected topographic digital elevation model (DEM) and 8 existing local 3-D models. Archival subsurface data include 10,237 geotechnical and stratigraphic boreholes, 3,312 picks from geophysical surveys, 15,902 field mapping sites and sections, 537 monitoring and water supply wells and 282,995 water well records. Roughly corresponding to regional aquifer and aquitard layers, primary model layers are (from oldest to youngest): Bedrock, Basal Aquifer, Lower Sediment, Regional Till, Post Regional Till Channel Fill, Glaciofluvial Sediment, Post Regional Till Mud, Glaciolacustrine Sand and Recent Sediment / Organics. Modelling was completed using an implicit modelling application (LeapFrog®) complemented by an expert knowledge approach to data classification and rules-based Expert System procedure for data interpretation and validation. An iterative cycle of automated data coding, intermediate model construction and manual data corrections, expert evaluations, and revisions lead to the final 3-D model. A semi-quantitative confidence assessment has been made for each model layer surface based on data quality, distribution and density. This surficial geology model completes the development of a series of regional 3-D geological and hydrogeological models for southern Ontario.
