“Automatically Extracted Buildings” is a raw digital product in vector format created by NRCan. The feature classes of this product delineate polygonal building footprints automatically extracted from airborne Lidar data, high-resolution optical imagery or other sources.The first feature class, Automatically Extracted Buildings by acquisition source, contains building footprints delivered according to the spatial extent of each source dataset used for extraction. When the spatial extents of acquisition sources overlap, footprints for the same building may therefore be duplicated in this class.The second feature class, Optimized Buildings Layer, is an assembled and harmonized layer derived from the buildings by acquisition source. Its objective is to provide a unique representation of each building footprint by removing duplicates and resolving overlaps between sources.

A building is a structure that has a roof and walls and stands more or less permanently in one place. Symbols are used when buildings and structures are permanent landmarks. Symbolized buildings have no side larger than 50 metres for 1:20,000 data or no side larger than 30 metres for 1:10,000 data. Small structures (including buildings less than 50 square metres) are not shown unless they constitute a point of orientation. This product requires the use of geographic information system (GIS) software.

STR - Facilities and structures (structure)Man-made construction. For example, resources describing buildings, museums, churches, schools, hospitals, factories, housing, monuments, and towers.

The Province is divided into nine administrative regions, having a total of 225 wildlife management units (WMU) for the purpose of efficient game management.

Buildings located on the territory of the City of Sherbrooke and belonging to one of the following categories: business, hospital, school or municipal building. These categories are respectively associated with subtype codes 2, 3, 4, and 5 attributes:ID - Unique IdentifierSubtype - Building Subtype Code (2 - Business, 3 - Hospital, 4 - Hospital, 4 - School, 4 - School, 5 - Municipal Building)**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Towers -- structures or buildings that are typically higher than their diameter and high relative to their surroundings -- are shown in this data set. They include: * communication towers * fire towers * microwave towers * radio towers * navigation beacons * lighthouses * lightning locators * meteorological towers

The First Nations geographic location dataset contains the geographic location of First Nations (groups and subgroups) in Canada as points as well as basic attributes data. The location identifies where the First Nations live. Each First Nation point represents its administrative office address as it is registered in Indigenous Services Canada (ISC) Band Governance Management System (BGMS). When the First Nation administrative office is located outside its associated most populated reserve boundary, adjustments are made to relocate the point within its boundaries, otherwise within the boundaries of another associated reserve or the city where the administrative office is located. When the administrative office or the First Nation is impossible to locate, the location is based on the best available information on the First Nation (e.g. official First Nation Web site). A connection with the BGMS is in place to ensure that any update to the system is reflected in the attributes data associated with the location of each First Nation.This dataset is Crown-Indigenous Relations and Northern Affairs Canada (CIRNAC) and Indigenous Services Canada (ISC) official source for First Nation geographic location on maps.

A legally defined __Islands Trust__ polygon was drawn from metes and bounds descriptions as written in Letters Patent for the Islands Trust in the province of British Columbia. A polygon dataset that includes all of the administrative areas currently in the __Administrative Boundaries Management System (ABMS)__ is available [here](https://catalogue.data.gov.bc.ca/dataset/legally-defined-administrative-areas-of-bc). A complimentary point dataset that defines the administrative areas is also available available [here](https://catalogue.data.gov.bc.ca/dataset/legally-defined-administrative-areas-of-bc-boundary-locations).

The __Counties of British Columbia__ contains areas of land within the Province of British Columbia representing legally defined administrative areas described in the County Boundary Act. The purpose of this division is for the administration of justice. The counties were delineated using provincial base mapping features, following the metes and bounds descriptions in the Letters Patent. A polygon dataset that includes all of the administrative areas currently in the __Administrative Boundaries Management System (ABMS)__ is available [here](https://catalogue.data.gov.bc.ca/dataset/legally-defined-administrative-areas-of-bc). A complimentary point dataset that defines the administrative areas is also available [here](https://catalogue.data.gov.bc.ca/dataset/legally-defined-administrative-areas-of-bc-boundary-locations).

The City dataset is comprised of all the polygons that represent Cities in Alberta. City is a municipality type defined under the authority of the Municipal Government Act. The formation of a City can occur when a majority of the buildings are on parcels of land smaller than 1850 square meters and there is a population of 10 000 or more.
