Alberta Geological Survey created a coal and coalbed methane (CBM) database to capture and manage CBM data. The database compiles different sources and contains information on 7923 wells (15,200 formation picks, 37,357 coal picks, 495 coal analyses and 363 vitrinite reflectance measurements). From this parent dataset, individual coal zones were evaluated. This record describes the Lethbridge Coal Zone's thickness isopach.

From this parent dataset, individual coal zones were evaluated. This record describes the Carbon Thompson Coal Zone's vitrinite reflectance measurements.

The coal zone boundary for the Taber Coal Zone is based on subcrops generated by Alberta Geological Survey Special Report 007 (Regional Evaluation of the Coalbed Methane Potential in the Plains and Foothills of Alberta, Stratigraphy and Rank Study). We used additional coal picks from various sources to refine the boundary.

This data set is an updated, GIS version of part of the Alberta Geological Survey's published Map No. 226, which in turn is a regional synthesis of various published and unpublished maps. The data represent the locations of thalwegs (paleo-channels) incised in the bedrock surface.

In 2014, the Alberta Energy Regulator (AER) initiated a Play-Based Regulation (PBR) pilot project as a step towards implementation of the Unconventional Regulatory Framework. One of the goals of the PBR pilot is to encourage companies in the unconventional play area to work together on plans for surface development to minimize the numbers of facilities and surface impacts. This dataset is one of a series created using earth observation imagery to assess surface change caused by energy exploration. The PBR area extends from Twp. 52, Rge. 7, W 5th Mer. to Twp. 70, Rge. 5, W 6th Mer., covering the towns of Edson, Fox Creek, Mayerthorpe, Whitecourt, Swan Hills, and Valleyview. For this digital data release, a land use and land cover classification dataset was derived from 2005 Landsat multispectral imagery for the PBR pilot area. The classification contains 13 classes: 0 - unclassified, 1 - exposed land/cut blocks/harvested areas, 2 - water bodies, 3 - transitional bare surfaces, 4 - mixed developed areas, 5 - developed areas, 6 - shoal, 7 - shrub land, 8 - grassland, 9 - agriculture areas, 10 - coniferous forest, 11 - broadleaf forest, and 12 - mixed forest. These categories can be used as baseline data for planning, managing and monitoring surface infrastructure needs and impacts.

This layer contains point features. The Strategic Land and Resource Planning documents can be accessed [here](https://www2.gov.bc.ca/gov/content/industry/crown-land-water/land-use-planning/regions). Current SLRP legal objective points are included in this layer. For all SLRP legal objective points (retired and current), please see the layer [Legal Planning Objectives - All - Point](https://catalogue.data.gov.bc.ca/dataset/8eb6e90e-8241-4215-8bb3-a204333a8625).

The Shore Unit Classifications Lines depict the most current Shorezone mapping lines for the Province of British Columbia. Shorezone is an aerial imaging, habitat classification, and mapping system used to inventory alongshore and across-shore geomorphological and biological attributes of the coast. Habitat attributes are interpreted from oblique aerial imagery acquired during the lowest tides of the year.

The Shorezone Biobanding Lines are a linear representation of the various types of biota (flora and fauna) and their distribution, or lack thereof, found in the shoreunit.

With this update the Canadian Hydrographic Service (CHS) offers both a complete inventory of bathymetric data free to the public for non-navigational as well as, for the first time, a collection of intensity image data products. To meet a growing desire in the scientific, commercial, environmental, and Indigenous communities for backscatter intensity data, the Canadian Hydrographic Service (CHS) has embarked on a Pilot Project to produce and distribute intensity imagery products from our current multibeam echo sounder (MBES) and LiDAR data holdings. MBES and LiDAR sensors collect two types of data, seafloor depth and backscatter intensity. The seafloor depth, or bathymetry is well represented on the CHS NONNA Data Portal. These products are available in a spatial resolution of 10 metres or 100 metres. While typically outside of our primary focus on bathymetry and charting for safe navigation, the CHS recognizes the importance of intensity data for the purposes of environmental and ecosystem management as well as the economic benefits associated with increased understanding of our marine environment. Backscatter intensity data, recorded in decibels (dB) is a measure of the strength of the return of a MBES pulse from the ocean floor to the multibeam receiver. These measures may be visualized as grey scale intensity map imagery. Backscatter intensity imagery can provide researchers with information about the surficial geology of the seafloor or objects on it. For example, hard, rocky materials will reflect more sound energy than softer materials such as mud. To be clear, the CHS is not attempting to create fully normalized and ground-truthed backscatter products. The CHS’s intensity and reflectance data holdings may be best understood as ‘collateral’ data encoded within the raw datagrams collected during MBES & LiDAR bathymetric surveys. **NEW** CHS NONNA INTENSITY A CHS NONNA Intensity product package is a ZIP file containing either an ASCII (x.y,dB) and/or a GEOTIFF image (w. intensity band) and the available metadata file. Variations in Intensity product resolution and quality are dependent on the contributing source data. TERMS OF USE To directly access the CHS NONNA Data Portal please follow this link - https://data.chs-shc.ca/login (Note: The data portal is NOT compatible with Internet Explorer browser). The Canadian Hydrographic Service (CHS) NONNA Data products are for NON-NAVIGATIONAL USE ONLY. Please see the Open Data Licence below and the CHS NONNA LICENCE viewable on https://data.chs-shc.ca/login and downloadable with the NONNA data, for the full terms and conditions governing the use of this data. ----- PRODUCT DESCRIPTION ----- The « NONNA » refers to the NON-Navigational nature of the data. Intensity data products contain NO depth information and as such are COMPLETELY UNSUITABLE FOR NAVIGATIONAL PURPOSES. The CHS NONNA Intensity Data products are packaged as a ZIP file containing an ASCII and/or GEOTIFF image dataset and a related metadata file. Resolution for data sources varies from data sources to data source and is dependent on the resolution of the source data it was derived from. The Intensity data supplied will be from various survey platforms, using a variety of MBES systems over the full extent of the CHS’s implementation of MBES and LiDAR surveying. All survey data provided will have been collected and processed to CHS data acquisition standards, which is to say these data were COLLECTED FOR THE EXPRESS PURPOSE OF SAFETY OF NAVIGATION and the need to maintain and update sounding data for CHS charts. Best practices for collecting MBES bathymetric data are not necessarily best practices for surveys where the express purpose is the production of intensity data products. As such, the data in our Archives may not have been collected to a standard best suited for producing high quality intensity data products. ----- DATUM ----- All CHS NONNA data sources are horizontally referenced to the World Geodetic System 1984 (WGS84) ESPG4326. CHS NONNA Intensity products contain no depth values and as such require no vertical reference. ----- DATA PRESENTATION ----- CHS NONNA Intensity products adhere to a different naming convention than the CHS NONNA Bathymetric products. Each product name has an unique ID that references the lineage of the contributing hydrographic source. Each contributing source is a hydrographic survey conducted by a single vessel using a single MBES. These products are available to view, query and download via the CHS NONNA Data Portal. The CHS NONNA Intensity products are ZIP files that contain product coverage (at varying resolution). The following formats are available for download: • 32-bit GeoTIFF • ASCII (XYI) These formats can be opened using a wide variety of GIS applications. *NOTE:* Gaps in the data may be visible where modern surveys have not yet been conducted, the data is not updated to Chart Datum (CD) or where legacy data has not yet been digitized. In addition, there may be data sources removed from the CHS NONNA Data Portal for further processing in the CHS’ Bathymetric Database, and as such, these datasets will not be available until such work is complete. Our investigation has uncovered existing intensity data products in our Archives that will be available for distribution immediately. However, there is a wealth of intensity near to completion. CHS NONNA Intensity products will be published as they become available. Data sources included in the CHS NONNA products may not have been subjected to the same level of quality assurance as those in official navigational products. *HELP* New users of the CHS NONNA Data Portal are encouraged to fully review the 'CHS NONNA Data Portal Guidance Document' (PDF) which is available below in the RESOURCES section of this page. • Publisher - Current Organization Name: Fisheries and Oceans Canada • Licence: Open Government Licence - Canada

2020 DATABASE (Excel): The joint federal-provincial Regional Geochemical Surveys (RGS) have been carried out in British Columbia since 1976 as part of the National Geochemical Reconnaissance (NGR) program to aid exploration and development of mineral resources. The British Columbia Geological Survey (BCGS) maintains provincial geochemical databases capturing information from multi-media surveys. This 2020 release of the most current and complete province-wide geochemical data set collected under the (RGS) program. The database was compiled from 116 original sources with 65,429 samples and about 5 million determinations analyzed using 18 methods in 18 laboratories. This release augments the database with new RGS data compiled from BCGS and Geoscience BC publications between 2016 and 2019. Compared with the data in the last release, data in this release have been given further quality control treatment and revision. For the ease of use and consistency with previously published data, the data set was generated from the RGS database in a flat tabular format. The 2020 data set, released as BCGS GeoGile 2020-08, is presented in two MS Excel files, ‘RGS2020_ data.xlsx’ and ‘RGS2020_metadata.xlsx’. The data tables capture locations, field observations, analytical results and laboratories, and geology underlying sample sites for stream-, lake- and moss-sediment, water and lake samples, heavy mineral concentrates, tree twig, and needle ash. The analytical determinations include up to 63 analytes from sediment samples and up to 78 analytes from water samples. These samples, collected at an average density of about 1 site per 7–13 km2, provide representative geochemical data for the catchment basin upstream from the sample site. The RGS currently covers approximately 80 percent of the province.
