Commercial and exploratory fisheries for Arctic Char, Salvelinus alpinus, provide significant economic opportunities for Nunavummiut in several Nunavut communities. Having an accurate understanding of the weight of the Arctic Char that are harvested is important for tracking harvest and for understanding how biological parameters may be changing over time as a result of exploitation and/or climactic and environmental changes. Unfortunately, most fish enter the processing plants as dressed (gills and viscera removed) and therefore conversion factors have to be applied to reconcile whole (round) weight from dressed weight. Here, we provide an updated conversion factor based on linear regression for Arctic Char from the Halokvik River (locally known as 30 Mile) near the community of Cambridge Bay. This conversion factor can be used moving forward as the Halokvik River continues to be commercially harvested.

A Linear Safety Feature is one of a number of various appliances/appurtenances that have been installed or constructed either alongside or as an integral part of the road infrastructure to reduce the severity or potential of accidents. It is a Linear feature

The roads and linear features in this data set were compiled and interpreted in association with the Vegetation Inventory (1995-2006). It is a representation of various linear features on the land base. The linear features were classified by the interpreters based on the NTDB classification system for roads and trails, at that time. When used in conjunction with other road or linear transportation networks, there may be duplication of lines and information.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Highway Planning and Design's 2018 Manitoba Road Network.The 2018 Manitoba Road Network was created by Manitoba Infrastructure, Highway Engineering, Highway Planning and Design (HPD). The department’s linear referencing system (LRS) uses Control Sections as a linear referencing method (LRM). The LRM is the digital representation of the Highway Network in Manitoba. The features indicate highway number and highway identity. This data was corrected using 1:60,000 digital ortho aerial photography dated from 1991-1998. Linear features have been updated on a yearly basis using GPS data, CAD files and 50cm imagery from 2007-2014, and is considered accurate to two-to-seven metres. Please note that this feature layer primarily contains only the roads that Manitoba Infrastructure is responsible for, i.e. Provincial Trunk Highways, Provincial Roads and Access Roads. However, you may also see Earth Roads (under construction) or Other roads (such as those passing through national parks and are federal responsibility).Fields included (Alias (Field Name): Field description.) OBJECTID (OBJECTID): Sequential, unique whole numbers are automatically generated. SHAPE (SHAPE): A field to hold geometry information.  ID (ID): Unique Identifier generated by Oracle. Control Section ID (CS_ID): Non unique identifier linking segment to its respective control section. Road Number Signed (ROAD_NO_SIGNED): The road number. Note though, that in the case of co-routes, the lower highway number appears. This is a text field and differs from ROAD_NO only where there are city routes, for example 1A. Road Location (ROAD_LOCATION): Access Road locations. Road Description (DESCRIPTION): A text description of the start and end locations of each segment.  Control Section Key (CS_KEY): An information rich key containing Region (two digits), Road Number (three digits), Section number (three digits), the Road Type (one character), and direction of travel (one character). MI Region (REGION_NO): The Manitoba Infrastructure region the segment is in. Regions 1-5. Road Number (ROAD_NO): The road number. Note co-routes will have the lesser highway number.  Section Number (SECTION_NO): The control section's section number. Start Kilometre (KM) (START_KM): The beginning of the Control Section (always zero). End Kilometre (KM) (END_KM): The number of kilometres to the end of the Control Section. Length Kilometres (KM) (LENGTH_KM): End Kilometre minus the Start Kilometre.  Road Type (ROAD_TYPE): The road type, i.e. PTHs, PRs, and Access Roads (Earth roads under construction may also be included).  Road Direction (ROAD_DIRECTION): A = ahead direction on a divided highway (i.e. following the digitizing direction), B = Back direction on a divided Highway (i.e. against the digitizing direction, and U= an undivided highway. Road Identity (ROAD_IDENTITY): Road identity i.e. Provincial Road, Earth Road, Access Road and Other Road. National Highway Classification (NATIONAL_HIGHWAY_CLASS): The national highway classification standard. Start Date (START_DATE): The date the segment was created in the database.  Inventory Year (INVENTORY_YEAR): The year the road segment was opened to the public.
