This GIS dataset depicts the surficial geology of the Thickwood Hills Area (NTS 84A/NE) (GIS data, point features). The data were created in geodatabase format and output for public distribution in shapefile format. These data comprise the point features of Alberta Geological Survey Map 555, Surficial Geology of the Thickwood Hills Area (NTS 84A/NE).

This GIS dataset depicts the surficial geology of the Thickwood Hills Area (NTS 84A/NE) (GIS data, line features). The data were created in geodatabase format and output for public distribution in shapefile format. These data comprise the line features of Alberta Geological Survey Map 555, Surficial Geology of the Thickwood Hills Area (NTS 84A/NE).

This GIS dataset depicts the surficial geology of the Thickwood Hills Area (NTS 84A/NE) (GIS data, polygon features). The data were created in geodatabase format and output for public distribution in shapefile format. These data comprise the polygon features of Alberta Geological Survey Map 555, Surficial Geology of the Thickwood Hills Area (NTS 84A/NE).

This is a polygon feature class representing large, named, physiographic features (areas) in the province, e.g., mountains, mountain ranges, ridges, plateaus, hills, and valleys.

The dataset accompanies Alberta Geological Survey Open File Report 2009-01. The dataset contains the results of geochemical analyses of rock samples from the Bad Heart Formation, Clear Hills region and Smoky River region (northwestern Alberta) collected by Alberta Geological Survey from 2004 to 2007. The data comprise elemental analyses of 325 rock samples, including ooidal ironstone, ooidal sandstone, sandstone, siltstone, shale, Bad Heart rubble and till, and conglomerate.

During a declared emergency event, this file represents an aggregated dataset that shows all of the active Orders and Alerts in the Province as initiated by the Local Governments or First Nations. When an Order or Alert is rescinded, its status changes to All Clear. The polygon is removed from this layer and copied to the [Historical Orders and Alerts dataset](https://catalogue.data.gov.bc.ca/dataset/historical-orders-and-alerts).

Historic placer mining areas in Yukon can be grouped into ten areas: Klondike; Sixtymile; Fortymile; Clear Creek; Moosehorn Range; Stewart River; Whitehorse South; Mayo; Dawson Range and Livingstone Creek. Each area has its own geomorphic setting and depositional history which is related to its glacial history. Several Quaternary glacial advances have been described in Yukon, and these are generally divided into three episodes, commonly known as the pre-Reid, Reid and McConnell, in order of oldest to most recent.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

This file represents an aggregated dataset that shows previously active Orders and Alerts in the Province as initiated by Local Governments or First Nations. Start dates, re-installment dates and All Clear Dates for each Evacuation Order and Alert are included in this multipart polygon dataset. The dataset includes records beginning summer 2017 until the present day. Orders and Alerts that are currently active are found in [Evacuation Orders and Alerts](https://catalogue.data.gov.bc.ca/dataset/evacuation-orders-and-alerts).

This catalog contains annual 30 m spatial resolution snow dynamics metrics for each snow-year from 2018-2019 to 2023-2024 for all of Canada. We gather all Landsat and Sentinel-2 images collected over Canada and identify the status of each pixel observation on the image collection date: snow (and ice), non-snow (i.e., land, water), unclear (i.e., clouds, shadows). We built an algorithm to calculate snow cover metrics for each pixel during each winter: start date of the first (and biggest) snow period [startF, startB], end date of the last (and biggest) snow period [endL, endB], number of days with snow cover in total (or in the biggest snow period) [lengthT, lengthB], number of snow periods (i.e., separated times with multiple confirmed snow observations) [periods], and a status classification (e.g., continuous snow, snow free) [status]. We do not obtain a clear observation every day because of satellite orbit frequencies and clouds. This means that timing-based metrics are identified by the middle date between two clear observations, with uncertainty quantified as half the length of the gap (i.e., ± days) [startF_u, startB_u, endL_u, endB_u, lengthT_u, lengthB_u].

This data collection contains the boundaries of the planning zones within the Livingstone-Porcupine Hills area. These datasets contain polygons representing the Planning Zones (Zone 2 – Enhanced and Zone 3 – Extensive) for both areas, as well as the Watershed Analysis Units of which there are seven (7) in the Livingstone PLUZ and three (3) in the Porcupine Hills PLUZ. For more detailed information, see the Livingstone-Porcupine Hills Land Footprint Management Plan (2018) and the detailed metadata for each individual dataset.
