Structural Culverts - 25k
The purpose of this dataset is to provide structural culvert locations along highways . The definition of a Structural Culvert is a culvert with span of 2 metres or greater. Drainage culverts have a diameter less than 2 metres and are not included in this dataset.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Ministry of Transportation (MOT) Culverts
A Culvert is a pipe (less than 3m in diameter) or half-round flume used to transport or drain water under or away from the road and/or right of way. Culverts that are greater than or equal to 3m in diameter are stored in the MoT Bridge Structure Road Dataset. It is a Point feature
Ministry of Transportation (MOT) Road Structures
The Road Structures on the highway that are maintained by the Ministry. Highway structures include bridges, culverts (greater than or equal to 3m diameter), retaining walls (perpendicular height greater than or equal to 2m), sign bridges, tunnels/snowsheds. Information is recorded in the Bridge Management Information System (BMIS)
FRI: Diameter (quadratic mean)
Diameter is an expression of the average diameter (cm) of trees at breast-height (1.3 m), calculated using a quadratic mean (QM_DBH). Available here as a diamter raster (GeoTIF) with a 20 m pixel resolution.Download: HereThe Saskatchewan Ministry of Environment, Forest Service Branch, has developed a forest resource inventory (FRI) which meets a variety of strategic and operational planning information needs for the boreal plains. Such needs include information on the general land cover, terrain, and growing stock (height, diameter, basal area, timber volume and stem density) within the provincial forest and adjacent forest fringe. This inventory provides spatially explicit information as 10 m or 20 m raster grids and as vectors polygons for relatively homogeneous forest stands or naturally non-forested areas with a 0.5 ha minimum area and a 2.0 ha median area. Diameter (QM_DBH) is an expression of the average diameter (cm) of trees at breast-height (1.3 m), calculated using a quadratic mean whereby individual trees are weighted in proportion to their basal area. QM_DBH is available here as a color-mapped 16-bit unsigned integer raster grid in GeoTIFF format with a 20 m pixel resolution. An ArcGIS Pro layer file (*.lyrx) is supplied for viewing QM_DBH data in the following 5 cm categories. Domain: [NULL, 0…60].

Tower
Towers -- structures or buildings that are typically higher than their diameter and high relative to their surroundings -- are shown in this data set. They include: * communication towers * fire towers * microwave towers * radio towers * navigation beacons * lighthouses * lightning locators * meteorological towers
Regional Deterministic Air Quality Analysis Cumulative Effects products
The Regional Deterministic Air Quality Analysis (RDAQA) is an objective analysis of surface pollutants which combines numerical forecasts from the Regional Air Quality Deterministic Prediction System (RAQDPS) and hourly observational data from monitoring surface networks over North America in order to produce a better description of the air quality at every hour. Chemical constituents include 03, SO2, and NO2 gases, as well as fine particulate matter PM2.5 (2.5 micrometers in diameter or less) and coarse particulate matter PM10 (10 micrometers in diameter or less). Geographical coverage is Canada and the United States. Data is available only for the surface level, at a horizontal resolution of 10 km. The products are presented as historical, annual or monthly, averages which highlight long-term trends in cumulative effects on the environment.
Pollution from wildfires Cumulative Effects products
The Regional Air Quality Deterministic Prediction System FireWork (RAQDPS-FW) carries out physics and chemistry calculations, including emissions from active wildfires, to arrive at deterministic predictions of chemical species concentration of interest to air quality, such as fine particulate matter PM2.5 (2.5 micrometers in diameter or less). Geographical coverage is Canada and the United States. Data is available at a horizontal resolution of 10 km. While the system encompasses more than 80 vertical levels, data is available only for the surface level. The products are presented as historical, annual or monthly, averages which highlight long-term trends in cumulative effects on the environment.
Soil Texture by Ecoprovince
The National Ecological Framework for Canada's "Soil Texture by Ecoprovince” dataset contains tables that provide soil texture information within the ecoprovince framework polygon. It provides soil texture codes and their English and French language descriptions as well as the percentage of the polygon that the component occupies.Soil texture indicates the relative proportions of the various soil separates (sand, silt, clay) as described by classes of texture. Soil separates are mineral particles, 2.0 mm in diameter and include: gravel 0.2 -7.5 cm and cobbles 7.5-25.0 cm. There are 12 texture group classes definitions and one class definition for Not Applicable (which indicates, for example, water, ice or urban areas).
