The Modern treaties (formerly known as the Post-1975 treaties) dataset contains geographic boundaries as well as basic attribute data representing signed agreements that were negotiated between Indigenous groups, the Government of Canada, and provincial and territorial governments after 1975. These boundaries represent the areas of Canada where Indigenous land rights and title have not been addressed by treaty or through other legal means. These boundaries represent the final result of a negotiated First Nation’s claimed area. These boundaries are usually not surveyed but help to delineate the geographic extent of the rights of Indigenous beneficiaries defined within the agreement. The Modern treaties dataset includes: 1) Overall Treaty Area (OTA) which is the broad area to which the agreement applies, often composed of the sum of the specific geographies defined within the treaty. 2) Treaty Settlement Lands that is wholly Indigenous-owned and forms part of the “land and cash” settlements that are integral to the treaty. This category belongs to the Department of Natural Resources Canada and can be found on the Open data website as ‘‘Aboriginal Lands’’ classified as ‘‘Land Claim’’. 3) Treaty-Specified Rights Areas which category pertains to areas (lands or waters) where specific rights, activities or responsibilities apply pursuant to the treaty. 4) Other Treaty-related Geography is the catch-all category for any remaining geographies that do not fit within the aforementioned categories but do form part of the OTA, such as lands or marine areas designated for conservation or for specific projects.For more information about Modern treaties, visit https://www.rcaanc-cirnac.gc.ca/eng/1100100028574/1529354437231#chp4. The Modern treaties dataset is one of multiple datasets representing treaties and agreements between the Crown and Indigenous peoples. The Crown-Indigenous treaties and agreements geospatial datasets represent the geographic boundaries of the solemn agreements between the Crown and Indigenous peoples that set out promises, obligations and benefits for parties. The following datasets are also available: 1) The Historic treaties (formerly known as the Pre-1975 treaties) dataset, which represents most signed treaties that were negotiated between Indigenous peoples and the Crown between 1725 and 1929.2) The Indigenous agreements dataset, which represents established protocols in place for consultation processes, self-government agreements, and other signed agreements between Indigenous groups and the Crown which do not fall into the aforementioned categories.The Modern treaties dataset is Crown-Indigenous Relations and Northern Affairs Canada (CIRNAC) and Indigenous Services Canada (ISC)’s primary source for Modern treaties geographic boundaries on maps.This dataset can also be viewed in the Aboriginal and Treaty Rights Information System (ATRIS). This web-based system provides access to information to inform governments, industry and other interested parties in determining their consultation obligations and in carrying out their consultation research.For more information, visit https://www.rcaanc-cirnac.gc.ca/eng/1100100014686/1609421785838.

Fisheries Information Summary System (FISS) layer of Historic (pre 2001) Fish Distribution Zones of BC streams. Includes salmonid rearing and spawning zones. Georeferenced to the stream centreline network layer of the 1:50,000 scale BC Watershed Atlas.

This layer is the current fire year burn severity classification for large fires (greater than 100 ha). Burn severity mapping is conducted using best available pre- and post-fire satellite multispectral imagery acquired by the MultiSpectral Instrument (MSI) aboard the Sentinel-2 satellite or the Operational Land Imager (OLI) sensor aboard the Landsat-8 and 9 satellites. Every attempt is made to use cloud, smoke, shadow and snow-free imagery that was acquired prior to September 30th. However, in late fire seasons imagery acquired after September 30th may be used. This layer is considered an interim product for the 1-year-later burn severity dataset (WHSE_FOREST_VEGETATION.VEG_BURN_SEVERITY_SP). Mapping conducted during the following growing season benefits from greater post-fire image availability and is expected to be more representative of tree mortality. #### Methodology: • Select suitable pre- and post-fire imagery or create a cloud/snow/smoke-free composite from multiple images scenes • Calculate normalized burn severity ratio (NBR) for pre- and post-fire images • Calculate difference NBR (dNBR) where dNBR = pre NBR – post NBR • Apply a scaling equation (dNBR_scaled = dNBR*1000 + 275)/5) • Apply BARC thresholds (76, 110, 187) to create a 4-class image (unburned, low severity, medium severity, and high severity) • Mask out water bodies using a satellite-derived water layer • Apply region-based filters to reduce noise • Confirm burn severity analysis results through visual quality control • Produce a vector dataset and apply Euclidian distance smoothing

Fisheries Information Summary System (FISS) layer of Historic (pre 2001) Fish Distribution Points of BC Streams. Points represent site locations where a fish species is rearing, spawning or observed or where a point is located at the mouth of a stream it indicates the presence of a fish species somewhere in the stream as a whole. Georeferenced to the stream centreline network layer of the 1:50,000 scale BC Watershed Atlas.

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.

The Historic treaties (formerly known as the Pre-1975 treaties) dataset contains geographic boundaries as well as basic attribute data representing signed treaties that were negotiated between Indigenous peoples and the Crown between 1725 and 1929. However, the Treaties of Peace and Neutrality, signed between 1701 and 1760, are not represented in this dataset because they do not have geographic boundaries that can be represented on a map. Apart from the Peace and Friendship Treaties, these boundaries represent the historic treaties signed after 1763, which provided large areas of First Nations land, to the Crown (transferring their Aboriginal title to the Crown) in exchange for reserve lands and other benefits. The Government of Canada recognizes 70 historic treaties in Canada signed between 1701 and 1923. These treaties include:• Treaties of Peace and Neutrality (1701-1760)• Peace and Friendship Treaties (1725-1779)• Upper Canada Land Surrenders and the Williams Treaties (1764-1862/1923)• Robinson Treaties and Douglas Treaties (1850-1854)• The Numbered Treaties (1871-1921)These boundaries are usually not surveyed but help to delineate the broad area described within the treaty. The boundaries are composed of the sum of specific geographies such as lakes, rivers, townships, mountains, administrative boundaries or height of land as mentioned in the treaties transcript. These boundaries are estimated based on written descriptions and should be used for informational and representational purposes only. If there is no geographic description included in the treaty, illustrative polygons may be used to represent locations where the signatory nations, as modern-day collectives, assert and/or exercise Section 35 rights.
