YESAA Assessment Districts - 250k
Yukon Environmental and Socio-economic Assessment Act (YESAA) Assessment District boundaries. This data set was created at a scale of 1:250,000 from metes and bounds provided in the "MINISTERIAL ORDER ESTABLISHING ASSESSMENT DISTRICT BOUNDARIES PURSUANT TO SECTION 20(1) OF THE YUKON ENVIRONMENTAL AND SOCIO-ECONOMIC ASSESSMENT ACT".Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

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.
Monthly Fraction of Vegetation Cover of Canada from Medium Resolution Satellite Imagery
FCOVER corresponds to the amount of the ground surface that is covered by vegetation, including the understory, when viewed vertically (from nadir). FCOVER is an indicator of the spatial extent of vegetation independent of land cover class. It is a dimensionless quantity that varies from 0 to 1, and as an intrinsic property of the canopy, is not dependent on satellite observation conditions. This product consists of a national scale coverage (Canada) of monthly maps of FCOVER indicator during a growing season (May-June-July-August-September) at 20m resolution.References:L. Brown, R.

Territory of the Agreement on Sustainable Water Resources in the Great Lakes and St. Lawrence River Basin in Quebec
This theme represents the limit of the Quebec territory of the Agreement on Sustainable Water Resources of the Great Lakes and St. Lawrence River Basin. It was generated from the grouping of watersheds at a cartographic scale of 1:20,000.

Biomass Agriculture Inventory 1-in-20 Probability
The “Biomass Agriculture Inventory 1-in-20 Probability” dataset is a table that contains the estimated 1-in-20 year low for agricultural residue yield and crop production for each Biomass Report Framework. It provides the fifth percentile values for the years 1985-2016.The table includes straw or stover information for barley, wheat, flax, oats and corn, and crop information for barley, wheat, flax, oats, corn, canola and soybean.This dataset also includes information about the type of tillage used in the area and demand for straw used for cattle bedding and feed. These values are derived from Statistics Canada data. Additionally, the dataset includes the amount of agricultural residue calculated as necessary to remain on the field to prevent soil degradation. Soil degradation is determined by the type of tillage in use as well as the landscape type of the area.
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).
Ontario Hydro Network - Shoreline
The Ontario Hydro Network (OHN) is a provincial medium scale originating from data with regional scales of 1: 10,000 in Southern Ontario, 1: 20,000 in Northern Ontario and 1: 50,000 in the Far North. The shoreline is taken from the OHN - Waterbody data class. This data is used for cartographic purposes and web mapping services. This product requires the use of geographic information system (GIS) software.

Ratio of children and seniors to working-age population (0 to 14 and 65 and over versus 15 to 64) by census division, 2016
This service shows the ratio of persons aged 0 to 14 and 65 and over (children and seniors) versus persons aged 15 to 64 (working-age) by census division. The data is a custom extraction from the 2016 Census - 100% data.This data pertains to the total population by age. 'Age' refers to the age at last birthday before the reference date, that is, before May 10, 2016. For additional information refer to 'Age' in the 2016 Census Dictionary.For additional information refer to 'Age' in the 2016 Census Dictionary.To have a cartographic representation of the ecumene with this socio-economic indicator, it is recommended to add as the first layer, the “NRCan - 2016 population ecumene by census division” web service, accessible in the data resources section below.
