On July 6, a train of 72 cars, carrying 100 tons of crude oil each, exploded in Lac-Mégantic. A high-resolution aerial photograph was collected by Aéro-Photo after the train derailment. This aerial photograph was provided and georeferenced by Aéro-Photo (1961) inc. Purpose: This aerial photograph makes it possible to identify the impact radius of the accident. The image web service (WMS) is offered as an open service. However, to obtain the raw image, please contact Aéro-Photo (1961) inc.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

All available bathymetry and related information for Lac Saint Cyr were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

This spatial layer displays Range Tenures (grazing and hay cutting licence and permits) administered by the Ministry of Forests, Lands and Natural Resource Operations. A Range Tenure is an area of Crown rangeland where a Range Act tenure applies. Tenure holders access a defined amount of forage through grazing (measured in Animal Unit Months) or hay (tonnage). Range Tenures apply only to Crown Land. In some cases, digital boundaries may overlap Private Land but these lands are not part of the Grazing area (as described in the legal description). Grazing may overlap waterbodies during drawdown (also described legally in the Tenure documents and where applicable, Range Use Plan). Livestock may graze islands and large bodies of water may act as Natural Range Barriers. March 3, 2023: Updates to the Range Tenure attribute table as described. Please contact Nancy.Elliot@gov.bc.ca if you have questions. To guide your use: 1. Layer contains RETIRED, PENDING, and ACTIVE Tenures (=Licenses and Permits); Select ACTIVE under attribute LIFE_CYCLE_STATUS_CODE to isolate all active tenures (status refers to spatial boundary status - therefore, a spatial boundary must be Retired in the Forest Tenure Administration system to have a status of retired); 2. Unique ID for Polygon is by RAN# in attribute FOREST_FILE_ID. Each tenure has own its RAN# (e.g. RAN07777). Multiple areas (polygons) belonging to the same tenure may have same RAN# with unique map block ids (e.g. RAN07777 A, RAN07777 B) 3. The field SUM_TENURE_ACTIVE_AREA_HA will provide, where LIFE_CYCLE_STATUS_CODE is ACTIVE, the total tenure area in Ha. For single block (polygon) tenures, this will be the same area as the polygon. Where there are multiple blocks, this will be the total sum area of all Active blocks. (Note this does not include PENDING or RETIRED tenure areas. Area is for Approved and Active Tenure boundaries. A block may be Approved but Pending, and therefore is not included). Review data for multipart vs multi polygons 4. AUTHORIZED_USE and TOTAL_ANNUAL_USE are for the entire Tenure; where there are multiple blocks, the total is over all blocks, seasonally distributed through different pastures 3. FILE_TYPE_CODE contains information on the type of Permit: • E01 - Grazing License • E02 - Grazing Permit • H01 - Haycutting License • H02 - Haycutting Permit 4. IF YOU ARE DOING SPATIAL ANALYSIS based on AREA --- Please note that tenures overlap either partially or wholly amongst tenure holders. One area may be shared by more than one Tenure holder and therefore there will be multiple congruent or partially overlapping polygons (multipart). If you want to do SPATIAL ANALYSIS based strictly on area, you must collapse or flatten the data using DISSOLVE so that the polygons are 1:1 with the land base (suggested approach)

All available bathymetry and related information for Lac Sante were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

This dataset is comprised of locations and current information for all schools for Kindergarten to Grade 12 in British Columbia. Indicators are included for schools that offer French programs including: Core French, Early French Immersion, Late French Immersion and Francophone Program.

The Regional Deterministic Wave Prediction System (RDWPS) produces wave forecasts out to 48 hours in the future using the third generation spectral wave forecast model WaveWatch III® (WW3). The model is forced by the 10 meters winds from the High Resolution Deterministic Prediction System (HRDPS). Over the Great Lakes, an ice forecast from the Water Cycle Prediction System of the Great Lakes (WCPS) is used by the model to attenuate or suppress wave growth in areas covered by 25% to 75% and more than 75% ice, respectively. Over the ocean, an ice forecast from the Regional Ice Ocean Prediction System (RIOPS) is used: in the Northeast Pacific, waves propagate freely for ice concentrations below 50%, above this threshold there is no propagation; in the Northwest Atlantic the same logic is used as in the Great Lakes. Forecast elements include significant wave height, peak period, partitioned parameters and others. This system includes several domains: Lake Superior, Lake Huron-Michigan, Lake Erie, Lake Ontario, Atlantic North-West and Pacific North-East.
