Location of rock samples collected during Precambrian mapping projects more recent than 1985 in northern Saskatchewan and stored at the Subsurface Laboratory.Location of rock samples collected during Precambrian mapping projects more recent than 1985 in northern Saskatchewan and stored at the Subsurface Laboratory. This is an on-going compilation so not all map projects are present. The data was created as a file geodatabase feature class and output for public distribution. **Please Note – All published Saskatchewan Geological Survey datasets, including those available through the Saskatchewan Mining and Petroleum GeoAtlas, are sourced from the Enterprise GIS Data Warehouse.  They are therefore identical and share the same refresh schedule. 

A "contaminant attenuation zone" is a three-dimensional zone that is, * located on land adjacent to a landfilling site, * in the subservice or extends into the subsurface, and * is used or is intended to be used for the attenuation of contaminants from the landfilling site to levels that will not have an unacceptable impact beyond the boundary of the zone. This product requires the use of geographic information system (GIS) software.

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.

The Soils Parent Materials raster prediction surface was crated using a Random Forest classifier trained with single component polygons from soils, terrain and ecosystem mapping projects, and 18 topographic predictor layers derived from the provincial 25m DEM. It is a prediction of mode of deposition of the soils parent material. The model was run by Ecoprovince and also enforced topographic constraints on some materials. The results of the Ecoprovince models were compiled into a provincial raster layer. The methodology and results are described in the research paper, Improved Soil Mapping in British Columbia, Canada with Legacy Soil Data and Random Forest Digital Soil Mapping Across Paradigms, Scales and Boundaries, 2016, ISBN : 978-981-10-0414-8 C.

An accurate depiction of road structure construction history of the Highway Network in Manitoba.Manitoba Infrastructure --> Highway Engineering--> Highway Planning and Design (HPD) manages the Highway Inventory System (HIS). This system tracks road structure and construction history of Manitoba's Road Network. Published annually, this layer aids provincial engineers in planning and managing construction projects, both present and future. The department’s linear referencing system (LRS) uses control sections as a linear referencing method (LRM). These control section are further divided into subsections. It is on these subsections that road structure and construction history are tracked in the highway inventory system database. This is the first year that HPD is making its annual HIS export available to the public. Please note that this feature layer primarily contains only the roads Manitoba Infrastructure is responsible for, i.e. Provincial Trunk Highways, Provincial Roads and Access Roads. It does not include municipal mile or grid roads. However, you may also see Earth Roads (under construction) or Other roads (such as those passing through national parks and are federal responsibility).
