Fetch and relative wave exposure indices for the coastal zone of the Newfoundland and Labrador Shelves bioregion
A relative exposure index (REI), unweighted fetch, effective fetch, and other fetch-based indices (i.e., sum, minimum) were calculated for the Newfoundland and Labrador (NL) Shelves bioregion. Due to the extensive coastline of the study region, this analysis was conducted for a 5km buffered region along the coast at a spatial resolution of 250m. Detailed methods on the selection of input points for the NL bioregion are included below.MethodsPreprocessing and input point selection:Land boundary files were obtained for Eastern Canada and the Canadian Arctic (NrCan 2017) at a scale of 1:50,000 as well as for Saint Pierre and Miquelon (Hijmans 2015), and the New England states (GADM 2012) however the scale at which these layers were produced is unknown. Land boundary files were merged into a single land polygon layer and watercourses reaching for in-land and/or above sea level were clipped from this polygon layer (Greyson 2021). A 5km buffer was generated around the NL provincial boundary. This buffer was then clipped by all land polygons to remove areas overlapping land polygons within the study area. All buffer segments intersecting the NAFO divisions within the NL bioregion were selected and the Union tool in ArcGIS Pro (v. 2.7.2) was used to fill-in gaps within the buffered area, creating a more continuous polygon. The buffered layer was then dissolved, and the NL provincial boundary polygon was erased from the buffered layer to create the study area polygon. A 250m fishnet was created and clipped to the study area (5km buffer layer) and the feature to point tool was used (with the “inside parameter checked”) to convert this grid into a point layer (approx. 1,000,000 points). The spatial resolution for all subsequent analyses was matched to the fishnet grid at 250m.ReferencesGADM database of Global Administrative Areas (2012). Global Administrative Areas, version 2.0.

Forest Inventory Ground Plots - Public Access
The Forest Analysis and Inventory Branch (FAIB) is responsible for coordinating and managing data collection and analyses from a range of different ground sampling programs that collect data on ground plots. This layer shows ground plots from the PSP and VRI programs. **Vegetation Resource Inventory (VRI):** ground samples primarily used to audit and verify key inventory attributes estimated during photo interpretation. These samples are not protected because they will not be revisited. **Permanent Sample Plots (PSP):** subjectively located fixed-area permanent plots, valued for their long-term re-measurement data to support development of growth-and-yield models in unmanaged stands across a range of stand and ecosystem types. Actual GPS coordinates are provided as protection is necessary. - Active PSPs = plot and buffer are protected from harvesting - Inactive PSPs = not protected from harvesting
Watercourse and Wetland Buffers
Buffer zones surrounding mapped watercourses and wetlands where forest activity is regulated on Crown land to maintain water quality and aquatic habitat.
High-Quality Agricultural Lands and Visual Impact Assessment Zones for Electric Energy Development
This dataset is provided by the Ministry of Affordability and Utilities, Electricity Sustainability and Innovation Branch, and identifies the high-quality agricultural lands, buffer zones, and visual impact assessment zones in Alberta designated under the Electric Energy Land Use and Visual Assessment Regulation (EELUVAR) made under the Alberta Utilities Commission Act. These areas apply to applications for the construction or operation of power plants under Alberta Utilities Commission Rule 007, unless exempted under the regulation. Restrictions on development of high-quality agricultural land are limited to privately owned land as per the regulation. This data product includes the following datasets: Land Suitability Rating System (LSRS) Class 2 and Class 3H Lands, Visual Impact Assessment Zones, and Buffer Zones. Visual Impact Assessment Zones and Buffer Zones contain both private and public lands.
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.
Base Stream and Flow Representation
The Single Line Hydrography Network (SLNET) contains all captured single line representations of hydrographic features. In addition, single line representations of polygonal features and single line arbitrary network connectors are in the file.
Oil and Gas Pipeline Segment Applications
Pipeline centre-lines associated with oil and gas pipeline activity and falling within the area representing the pipeline right of way. This dataset contains line features for proposed applications collected through the BC Energy Regulator's Application Management System (AMS). The dataset is updated nightly.
Trapping Concessions - 250k
Registered Trapping Concessions (RTCs) are legal boundaries that define an area where the holder of the concession has the exclusive right to trap furbearing animals. Because trapping is done primarily along waterways, RTCs are often defined by watersheds, using height of land (ridges and mountain peaks) as their boundaries. This is the opposite of GMAs which are defined by mountains. Sometimes RTCs are grouped together to form a Group Trapping Concession (in which groups of individual share the right to trap). This may or may not involve the elimination of the component RTC boundaries. The Yukon has 360 RTCs and 13 Group Trapping Concessions. Only Kluane National Park, Kluane Wildlife Sanctuary, and Ddhaw Ghro Habitat Protection are are not covered by RTCs. This data was built using the 1:250,000 National Topographic Data Base (NTDB) as the digitizing base.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .
