Roadside barriers are physical obstructions to retain vehicles that have left the travelling lane on the road. In the Yukon, the most common barriers are W-beam (also known as guiderail) and concrete roadside barrier (CRB, also known as jersey barrier).Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

A Guardrail is a barrier fastened to the end of a bridge abutment, along the shoulder of a road or between travel lanes of opposing traffic. It is a Linear feature

A Range Pasture is a grazing area enclosed and separated from other areas by fencing or other barriers (e.g. Natural Range Barrier). May be the management unit of grazing land as reflected in a Range Use Plan. Range Pastures are administrative and not legal boundaries.

Fisheries and Oceans Canada (DFO), in partnership with other government organizations, indigenous groups, and community stakeholders, monitor the migratory return of Atlantic salmon to rivers each season. In Newfoundland and Labrador, there are 15 management areas, known as Salmon Fishing Areas (SFAs), with over 400 rivers containing populations of spawning salmon. Each year, salmon populations are enumerated at monitoring facilities (counting fences or fishways) on several rivers throughout the province. Monitoring begins in April or May for the downstream smolt run and in June or July for the upstream adult run and varies in timing by year and river. Not all rivers are monitored annually and years with incomplete data are often attributable to environmental factors that delay or stop monitoring during a season (e.g. fence washout due to elevated water levels). Days with zero counts can be attributable to no fish and/or closures to the monitoring facility. While monitoring facilities are used primarily to count Atlantic salmon, other freshwater fish may also be enumerated if encountered. The counts from these monitoring facilities, in addition to angling information and other monitoring activities, provide information for estimating returns for the annual stock assessment, which is an important part of conservation and management of Atlantic salmon populations in Newfoundland and Labrador. This data contains information for Atlantic salmon only.

Fetch is a proxy for wind-wave action and exposure. Estimates of fetch over a total of 39,938 km of the BC coastline were calculated at 50 m intervals, yielding 799,220 near shore fetch points. Fetch was calculated for five regions in Pacific Canada: Haida Gwaii (HG), North and Central Coast (NCC), Queen Charlotte and Johnstone Straits (QCS), Salish Sea (SoG), and West Coast Vancouver Island (WCVI). For all regions, a bearing interval of 5 degrees was used to generate fetch lines for each point along the shoreline, resulting in 72 fetch lines per point. A maximum fetch distance of 200 km was used to ensure the barrier effect of Haida Gwaii was captured.Supplementary information provided includes the fetch geometry calculator script and user guide (Gregr 2014) and a report on the fetch processing objectives, process, and results (Gregr 2015).

BLKPASSAGE_OFFICIAL is one of the important layers for Saskatchewan Upgraded Road Network (SURN) and National Road Network (NRN). The BLKPASSAGE_OFFICIAL provides the information of road blocked passage to clients that require accurate, relatively up-to-date and detailed description of Saskatchewan Road Network.BLKPASSAGE_OFFICIAL, This layer contains data for a structure indicating a physical barrier on a Road Element built to prevent or control further access. BLKPASSAGE_OFFICIAL contains all the blocked passage points in the Saskatchewan. BLKPASSAGE_OFFICIAL is an important part of the Saskatchewan road network dataset. Each point geometry " BLKPASSAGE" has unique Identifiers (NID). "NID" National Identifier is used to manage the updates between data producer and data users.

A Retaining Wall is a structure designed to protect the road infrastructure by retaining materials on the fill side to prevent road bed slips and by retaining materials on the cut side to prevent the road surface from being covered by debris. Retaining walls that are greater than or equal to 2m in height are stored in the MoT Bridge Structure Road dataset. It is a Linear feature

A Railroad Crossing is where the road surface is common to both the Railway Authority and the Ministry of Transportation Road Network; also includes overhead and under passes. It is a Point feature

Ministry of Transportation District Boundary is an exclusive area within a region that the Ministry organizational unit is responsible for. Each Ministry District is partitioned into one or more non-overlapping Contract Areas that cover the entire Ministry District

This product provides the boundaries for the 25 drainage regions in Canada and the five ocean drainage areas. These drainage regions cover all of the area within the coastal boundaries of Canada.These files were produced by Statistics Canada, Environment, Energy and Transportation Statistics Division, 2009, special tabulation of data from Pearse, P.H., F. Bertrand and J.W. MacLaren, 1985, Currents of Change: Final Report of the Inquiry on Federal Water Policy, Environment Canada, Ottawa.
