Geological map of the Arctic, 1:5 000 000
As part of the International Polar Year (IPY) 2007'08 and 2008'09 activities, and related objectives of the Commission for the Geological Map of the World (CGMW), nations of the circumpolar Arctic have co-operated to produce a new bedrock geology map and related digital map database at a scale of 1:5 000 000. The map, released in north polar stereographic projection using the World Geodetic System (WGS) 84 datum, includes complete geological and physiographic coverage of all onshore and offshore bedrock areas north of latitude 60° north.
Atlas of Canada National Scale Data 1:15,000,000 2012-2017
This collection is a legacy product that is no longer maintained. It may not meet current government standards.Users of Atlas of Canada National Scale Data 1:15,000,000 (release of May 2017) should plan to make the transition towards the new CanVec product.The Atlas of Canada National Scale Data 1:15,000,000 Series consists of boundary, coast and coastal islands, place name, railway, river, road, road ferry and waterbody data sets that were compiled to be used for atlas small scale (1:15,000,000 to 1:30,000,000) mapping. These data sets have been integrated so that their relative positions are cartographically correct. Any data outside of Canada included in the data sets is strictly to complete the context of the data.
Glacial Drift Thickness
This dataset represents surface to bedrock isopach (thickness in metres) map of glacial drift for the Province of Saskatchewan at 1:1 000 000 scale.This dataset represents surface to bedrock isopach (thickness in metres) map of glacial drift at 1:1 000 000 scale. This 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.
Base Waterbody Polygon Arc
Base waterbody polygon arcs are feature type, source and capture date attributed arcs that make up the boundaries of base waterbody polygons in the Base Features Hydrography geospatial dataset. These arcs were collected from conversion processes of 1:20 000, 1:50 000 and AVI Provincial mapping datasets and 1:50 000 National Topographic Data Base (NTDB).
NTS Grid 1:20 000
This dataset is produced for the Government of Alberta and is available to the general public. Note that the distribution contact is different for the general public than for Government of Alberta ministries. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. The National Topographic System of Canada (NTS) is a national mapping reference grid defined by Natural Resources Canada (NRCan) that is based on degrees of latitude and longitude. Starting at the Prime Meridian and at the Equator, the 1:50 000 grid is formed by intersecting every 1/8 degree of the meridians with every 1/4 degrees of parallels. It is also true that the standard 1:20 000 NTS block is broken down into 4 1:20 000 blocks that are labelled by quadrant. Each polygon in the grid is designated with a two digit number. a single letter. two additional numbers and a two letter quadrant value (Example 83H08NE). The 1:20 000 NTS grid was developed to support the Provincial Digital Base Mapping Project and is not part of the formal NRCan NTS program. The province of Alberta is covered by 2838 complete and 269 partially complete 1:20 000 NTS blocks.
Indexes of the National Topographic System of Canada
Topographic maps produced by Natural Resources Canada conform to the National Topographic System (NTS) of Canada. Indexes are available in three standard scales: 1:1,000,000, 1:250,000 and 1:50,000. The area covered by a given mapsheet is determined by its latitude and longitude. 1:1,000,000 mapsheets are identified by a combination of three numbers (e.g. 098). 1:250,000 mapsheets are identified by a combination of numbers, and letters ranging from A through P (e.g. 098C). Sixteen smaller segments (1 to 16) form blocks used for 1:50,000 mapping (e.g. 098C03).
Ecological Land Classification (ELC)
Ecological Land Classification (ELC) is an approach which endeavours to subdivide the landscape into significant ecological units and to organize complex interrelationships into identified geographical areas with similar properties. It is a hierarchical system that captures information at the following scales as per the Ecological Land Classification and Evaluation Reference Manual (1980): Ecoprovince - >1:3 000 000 Ecoregion - 1:1 000 000 - 1:3 000 000 Ecodistrict - 1:250 000 - 1:1 000 000 Ecosection - 1:100 000 - 1:250 000 Ecosite - 1:10 000 - 1:20 000 Ecoelement - 1:1 000 - 1:5 000. Note that the upper two levels are referred to as Natural Region and Natural Subregion in the more recent Ecological Land Classification reports. There are also some variations in this hierarchy for individual study areas. The data is available as TIFF image files packaged together with the reports and other supporting documents divided alphabetically.
Geological map of Canada, 1:5 000 000
The map displays bedrock formations at or near the surface of the land, on the sea floor above the continental crust that forms the Canadian landmass, and oceanic crust surrounding the landmass. The bedrock units are grouped and coloured according to geological age and composition. The colours of offshore units and oceanic crust are paler and more generalized than those on land, although the constituent units offshore are still easily discernible from their dashed boundaries. This colour design, coupled with the use of a white buffer zone at the coast allows the coastline of Canada to be readily distinguished and still show the grand geological architecture of the Canadian landmass.The map also shows major faults that have disrupted the Earth's crust, onshore and offshore, and a variety of special geological features such as kimberlite pipes, which locally contain diamonds, impact structures suspected to have been caused by meteorites, and extinct and active spreading centres in the surrounding oceans.
NTS Grid 1:50 000
This dataset is produced for the Government of Alberta and is available to the general public. Note that the distribution contact is different for the general public than for Government of Alberta ministries. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. The National Topographic System of Canada (NTS) is a national mapping reference grid defined by Natural Resources Canada (NRCan) that is based on degrees of latitude and longitude. Starting at the Prime Meridian and at the Equator, the 1:50 000 grid is formed by intersecting every 1/4 degree of the meridians with every 1/2 degrees of parallels. It can also true that the standard 1:250 000 NTS block is broken down into 16 1:50 000 blocks that a numbered south to north alternating east to west then west to east from one to 16. Each polygon in the grid is designated with a two digit number. a single letter and two additional numbers (Example 83H08). The province of Alberta is covered by 670 complete and 131 partially complete 1:50 000 NTS blocks.
