Slope/Aspect Categories in Mule Deer Winter Range - Cariboo Region
Slope/aspect categories within mule deer winter range in the Cariboo Region.
High Resolution Digital Elevation Model Mosaic (HRDEM Mosaic) - CanElevation Series
The High Resolution Digital Elevation Model Mosaic provides a unique and continuous representation of the high resolution elevation data available across the country. The High Resolution Digital Elevation Model (HRDEM) product used is derived from airborne LiDAR data (mainly in the south) and satellite images in the north. The mosaic is available for both the Digital Terrain Model (DTM) and the Digital Surface Model (DSM) from web mapping services. It is part of the CanElevation Series created to support the National Elevation Data Strategy implemented by NRCan. This strategy aims to increase Canada's coverage of high-resolution elevation data and increase the accessibility of the products.Unlike the HRDEM product in the same series, which is distributed by acquisition project without integration between projects, the mosaic is created to provide a single, continuous representation of strategy data. The most recent datasets for a given territory are used to generate the mosaic. This mosaic is disseminated through the Data Cube Platform, implemented by NRCan using geospatial big data management technologies. These technologies enable the rapid and efficient visualization of high-resolution geospatial data and allow for the rapid generation of dynamically derived products. The mosaic is available from Web Map Services (WMS), Web Coverage Services (WCS) and SpatioTemporal Asset Catalog (STAC) collections. Accessible data includes the Digital Terrain Model (DTM), the Digital Surface Model (DSM) and derived products such as shaded relief and slope.The mosaic is referenced to the Canadian Height Reference System 2013 (CGVD2013) which is the reference standard for orthometric heights across Canada.Source data for HRDEM datasets used to create the mosaic is acquired through multiple projects with different partners.Collaboration is a key factor to the success of the National Elevation Strategy. Refer to the “Supporting Document” section to access the list of the different partners including links to their respective data.
Canadian Digital Surface Model, 2000
This is a legacy product that is no longer supported. It may not meet current government standards.The Canadian Digital Surface Model (CDSM) is part of Natural Resources Canada's altimetry system designed to better meet the users' needs for elevation data and products. The 0.75-second (~20 m) CDSM consists of a derived product from the original 1-second (30 m) Shuttle Radar Topographic Mission (SRTM) digital surface model (DSM). In these data, the elevations are captured at the top of buildings, trees, structures, and other objects rather than at ground level.A CDSM mosaic can be obtained for a pre-defined or user-defined extent. The coverage and resolution of a mosaic varies according to the extent of the requested area.Derived products such as slope, shaded relief and colour shaded relief maps can also be generated on demand by using the Geospatial-Data Extraction tool. Data can then be saved in many formats.The pre-packaged GeoTiff datasets are based on the National Topographic System of Canada (NTS) at the 1:50 000 scale; the NTS index file is available in the Resources section in many formats.
Thematic Soil Maps of Manitoba
The “Thematic Soil Maps of Manitoba” is a revised and condensed version of the Manitoba Detailed Soils Database produced by CANSIS. It contains data relating to the soils slope, drainage, agricultural capability, erosion potential, and surface texture.
Slope class (BDTQ)
__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__.**Slope classes** express the slope of the terrain in a relatively homogeneous area with a minimum area of 0.5 ha. They are generated from a numerical model that groups terrain slopes into six classes:+ 0-3% zero + Low by 4-8% + 9-15% soft + Moderate by 16-30% + 31-40% strong + Steep by 41% or moreThese data cover almost all of Quebec south of the 52nd parallel. This map is presented in two groups: grouping at the provincial level and grouping at the scale of 1/250,000. Each grouping represents an assembly of sheets produced on a scale of 1/20,000.The datasets were originally produced in 2005 and then updated in 2006. In 2010, they were enhanced with slope information for the northernmost part. No updates have been made since then.__For more information, please refer to the document: [Products presenting the concept of slope] (https://diffusion.mffp.gouv.qc.ca/Diffusion/DonneeGratuite/Foret/DONNEES_FOR_ECO_SUD/Classes_pente/01-Documentation/Produits_presentant_la_notion_de_pente.pdf)____ ⚠️ Notes: __ The numerical terrain model is prepared from the level curves and altitude points that come from the topographic map at a scale of 1/20,000 and 1/50,000 from the Quebec Topographic Database (BDTQ). This geographic database was produced in 2010 and has never been updated.__ 🕰️ Former names:__ Numerical slope classes, Slope class**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
Thematic Soil Maps of Saskatchewan
The “Thematic Soil Maps of Saskatchewan” is a revised and condensed version of the Saskatchewan Detailed Soils Database produced by CANSIS. It contains data relating to the soils slope, drainage, agricultural capability, erosion potential, and surface texture.
Slope/Aspect Habitat Type Limitations in Mule Deer Winter Range – Cariboo Region
Slope/Aspect habitat type limitations (high, moderate, low) in mule deer winter range within the Cariboo Region. These limitations apply only to interior douglas fir (IDF) and bunch grass biogeoclimatic zones within mule deer winter range.
Canadian Digital Elevation Model, 1945-2011
This collection is a legacy product that is no longer supported. It may not meet current government standards.The Canadian Digital Elevation Model (CDEM) is part of Natural Resources Canada's altimetry system designed to better meet the users' needs for elevation data and products.The CDEM stems from the existing Canadian Digital Elevation Data (CDED). In these data, elevations can be either ground or reflective surface elevations.A CDEM mosaic can be obtained for a pre-defined or user-defined extent. The coverage and resolution of a mosaic varies according to latitude and to the extent of the requested area.Derived products such as slope, shaded relief and colour shaded relief maps can also be generated on demand by using the Geospatial-Data Extraction tool. Data can then be saved in many formats.The pre-packaged GeoTiff datasets are based on the National Topographic System of Canada (NTS) at the 1:250 000 scale; the NTS index file is available in the Resources section in many formats.
Flammulated Owl Habitat Suitability - Cariboo NR Region
This polygon dataset identifies the habitat suitability rating for Flammulated Owl (FLOW) within the Cariboo Natural Resource Region. The habitat suitability rating is based on Biogeoclimatic Ecosystem Classification (BEC), forest age class, crown closure, tree species, harvest activity, silviculture activity, slope and aspect.
Representative Area Ecological Reserve
The Representative Area Ecological Reserves Regulations are part of the Protected Lands of Saskatchewan.The Representative Area Ecological Reserves Regulations are part of the Protected Lands System of Saskatchewan. Selected to represent specific enduring features (specific soil attribute combinations based on soil development, parent material, surface form, slope derived from the Soil Landscapes of Canada, Saskatchewan database, Version 2.1). Areas set to protect ecologically representative areas of Saskatchewan's ecoregions.
