Radiocarbon dates, offshore Canada
Radiocarbon dates are derived from organic samples collected through marine and coastal expeditions of the Geological Survey of Canada Atlantic and Pacific. These efforts were conducted primarily to better understand the spatial and temporal coverage of sediments and seabed-fast marine ice during the last deglaciation. The quality of these data varies - ranging from imprecise bulk samples and more accurate AMS estimates derived from single shell fragments. These data are ordered in the menu in 1000 year divisions. By default, only conventional radiocarbon ages are displayed, and reservoir-corrected and measured ages are hidden.
Lithology of Ground Water Wells
Point features showing the locations of groundwater wells which have lithology recorded. Each record in the dataset represents a lithology interval. Because each water well often has multiple lithology layers recorded, there will often be multiple points overlapped at each well location. For the locations of all water wells in BC (without lithology), please see: https://catalogue.data.gov.bc.ca/dataset/e4731a85-ffca-4112-8caf-cb0a96905778 > NOTE: When choosing to download this GIS dataset below, there can be errors when trying to download the entire province. The large file size is a problem for the default file format (shapefile). > If you need to download the entire province, please choose a different file format (e.g. ESRI File Geodatabase). > If you need to download in shapefile format, please use an area of interest (AOI).
Forest Lorey's Height 2015
Forest Lorey's Height 2015Lorey's mean height. Average height of trees weighted by their basal area (m). Products relating the structure of Canada's forested ecosystems have been generated and made openly accessible. The shared products are based upon peer-reviewed science and relate aspects of forest structure including: (i) metrics calculated directly from the lidar point cloud with heights normalized to heights above the ground surface (e.g., canopy cover, height), and (ii) modelled inventory attributes, derived using an area-based approach generated by using co-located ground plot and ALS data (e.g., volume, biomass). Forest structure estimates were generated by combining information from lidar plots (Wulder et al. 2012) with Landsat pixel-based composites (White et al. 2014; Hermosilla et al. 2016) using a nearest neighbour imputation approach with a Random Forests-based distance metric. These products were generated for strategic-level forest monitoring information needs and are not intended to support operational-level forest management. All products have a spatial resolution of 30 m. For a detailed description of the data, methods applied, and accuracy assessment results see Matasci et al. (2018).

Forest height in Canada 2011
The raster maps depict a suite of forest attributes in 2001* and 2011 at 250 m by 250 m spatial resolution. The maps were produced using the k nearest neighbours method applied to MODIS imagery and trained from National Forest Inventory photo plot data. For detailed information about map production methods please refer to Beaudoin et al. (2018) "Tracking forest attributes across Canada between 2001 and 2011 using the k nearest neighbours mapping approach applied to MODIS imagery." Canadian Journal of Forest Research 48, 85-93. https://cfs.nrcan.gc.ca/publications?id=38979 The map datasets may be downloaded from https://nfi.nfis.org/downloads/nfi_knn2011.zip or https://open.canada.ca/data/en/dataset/ec9e2659-1c29-4ddb-87a2-6aced147a990 * Note: the forest composition (leading tree genus) map depicts forest attributes in 2001.How can this data be used?The resolution and accuracy of these map products are best suited for strategic-level forest reporting and informing policy and decision making at regional to national scales. As these maps also offer a coherent set of quantitative values for a large suite of forest attributes, they can be used as baseline information for modelling and in calculations such as merchantable forest volume or percentage of tree species. It is also possible to overlay these maps with other maps produced on the same pixel grid to make assessments of disturbance impacts, such as fire and harvests.
Program Activity Tracking for Habitat (PATH) system
The Government of Canada continues to strive to be ever more open and transparent. This means a government that is open by default providing better digital capacity and services for Canadians.Under a modernized Fisheries Act, Fisheries and Oceans Canada (DFO) has made available an online Fisheries Act (FA) Registry that facilitates access to data and information, including geospatial data, about projects as well as regulatory process information. The new online version of the FA Registry is now available to Canadians. The FA Registry is currently accessible through the Common Project Search Portal, a one-stop online location for Canadians to search and browse through DFO authorizations as well as projects and assessments submitted to the Impact Assessment Agency of Canada and Transport Canada.DFO will be undertaking continuous development of the Fisheries Act Registry. This release is the second step towards implementing the full FA Registry that will provide additional content as well as new features to the FA Registry, increasing transparency and proactive disclosure as well as improving digital capacity and service for Canadians.

Harvest Year/Mask 1985-2015
Annual mapping of national level forest harvesting for Canada detected inclusive of 1985 to 2015 from Landsat satellite imagery.This dataset is composed of two layers: (1) binary harvest mask, and (2) year of harvest disturbance detection. The information outcomes represent 31 years of harvesting activity in Canada’s forests, derived from a single, consistent, spatially-explicit data source in an automated manner. Time series of Landsat data with 30-m spatial resolution were used to characterize national trends in stand replacing forest disturbances, including those attributed to harvest for the period 1985–2015 for Canada's 650 million hectare forested ecosystems (Hermosilla et al. 2016).
