This project was carried out thanks to the financial support of component 2.2 of the MAMAH Regions and Rurality Fund (FRR). The updates were made using orthophotos from spring 2020. The project covers the territory of the MRCs of Haut-Saint-Laurent, Haute-Yamaska, Haute-Yamaska, Roussillon, Rouville, Vaudreuil-Soulanges as well as the agglomeration of Longueuil.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This is a legacy product that is no longer supported. It may not meet current government standards. Canada3D is a digital elevation model (DEM) produced by the Canadian Forestry Service, Ontario region. The DEM consists of an ordered array of ground elevations providing coverage of the Canadian landmass. It has been derived from the cells of the Canadian Digital Elevation Data (CDED) at the 1:250 000 scale. Canada3D is available in two levels of detail: grids regularly spaced at 30 or 300 arc seconds. Canada3D 30 and 300 are recorded separately in ASCII format. The elevation values are expressed in metres with respect to mean sea level (MSL), in accordance with the North American Datum of 1983 (NAD83).

The 1 cm resolution digital surface model (DSM) was created from unmanned aerial vehicle (UAV) imagery acquired from a single day survey, July 28th 2016, in Cambridge Bay, Nunavut. Five control points taken from a Global Differential Positioning System were positioned in the corners and the center of the vegetation survey. The DSM covering 525m2 was produced by Canada Centre for Remote Sensing /Canada Centre for Mapping and Earth Observation. The UAV survey was completed in collaboration with the Canadian High Arctic Research Station (CHARS) for northern vegetation monitoring research.

In 2015, the Earth Observation Team of the Science and Technology Branch (STB) at Agriculture and Agri-Food Canada (AAFC) repeated the process of generating annual crop inventory digital maps using satellite imagery to for all of Canada, in support of a national crop inventory. A Decision Tree (DT) based methodology was applied using optical (Landsat-8) and radar (RADARSAT-2) based satellite images, and having a final spatial resolution of 30m. In conjunction with satellite acquisitions, ground-truth information was provided by provincial crop insurance companies and point observations from the BC Ministry of Agriculture and our regional AAFC colleagues.

La donnée a été créée ou dérivée à partir d'images de véhicules aériens non habités (UAV) acquises à partir d'une enquête d'une journée, le 28 juillet 2016, à Cambridge Bay, au Nunavut. Cinq points de contrôle provenant d'un système de positionnement différentiel global ont été positionnés dans les coins et au centre de l'étude de la végétation. Les jeux de données suivants couvrent une superficie de 525m2 et ont été produits par le Centre canadien de télédétection / Centre canadien de cartographie et d'observation de la Terre: - UAV modèle d'hauteur de la végétation, Cambridge Bay, Nunavut - UAV modèle numérique de surface (MNS) dans Cambridge Bay, Nunavut - Parcelle de végétation - UAV orthomosaïque de Cambridge Bay, Nunavut - Parcelle de végétation L'enquête sur les UAV a été menée en collaboration avec La Station canadienne de recherche dans l’Extrême-Arctique (SCREA) pour la recherche sur la surveillance de la végétation nordique.

The distribution of Property - Municipal Boundaries data to the public is provided by AltaLIS Ltd., distributing agent for the Alberta Data Partnerships Ltd. (ADP), formerly Spatial Data Warehouse Ltd. (SDW), on behalf of the Government of Alberta. The Property - Municipal Boundaries data includes a GIS-ready mapping database created by Alberta Environment and Parks and includes the following: Counties, MD’s, Special Areas, Improvement Districts, Cities, Towns, Villages, Summer Villages and Hamlets. This product is available from AltaLIS Ltd. under the Province of Alberta’s ‘Open Government Licence’.

The distribution of Base - Small Scale Topographic data to the public is provided by AltaLIS Ltd., distributing agent for the Alberta Data Partnerships Ltd. (ADP), formerly Spatial Data Warehouse Ltd. (SDW), on behalf of the Government of Alberta. The Base - Small Scale Topographic data includes a vector mapping database created by Alberta Environment and Parks and includes the following: 1:250 000 Base, 1:1 000 000 Base and 1:2 000 000 Base.

The VMap1 collection is a legacy product that is no longer supported. It may not meet current government standards. VMap1 is a vector digital topographic reference product developed by Natural Resources Canada (NRCan) and The Department of National Defence (DND). VMap1 complies with international military specifications vector map, level 1. There are 24 VMap1 libraries covering the Canadian territory. The National Topographic Data Base (NTDB) at scale of 1:250 000 is the main source used to populate the Canadian VMap1 Libraries. Administrative Boundaries from Statistics Canada are used to add international borders, provincial and Indian reserve limits. NRCan paper maps at scale of 1:250 000 and the information in the Canadian Geographical Names Data Base (CGNDB) are used to capture the names. The JOG (Joint Operations Graphic) paper maps were used by DND for the production of libraries 37, 38 and 66. Topographic features mainly from the NTDB have not been updated. VMap1 is published once and no product revision is planned.

In 2009 the Earth Observation Team of the Science and Technology Branch (STB) at Agriculture and Agri-Food Canada (AAFC) began the process of generating annual crop inventory digital maps using satellite imagery. Focusing on the Prairie Provinces, a Decision Tree (DT) based methodology was applied using both optical (AWiFS, Landsat-5) and radar (RADARSAT-2) based satellite imagery, and having a final spatial resolution of 56m. Methods were also developed to enhance the optical classification with RADARSAT-2 imagery, addressing issues associated with cloud cover. In conjunction with satellite acquisitions, ground-truth information was provided by provincial crop insurance companies and point observations from our regional AAFC colleagues. The overall process for Crop Inventory Map includes: satellite data acquisition; field data acquisition for classification training and accuracy assessment; and, operational implementation of the classification methodology. The initial methodology was developed in partnership with AAFC Research Branch, and supported in part by the Canadian Space Agency. The long-term objective of this endeavour is to expand from the Prairies and produce an annual crop inventory of the entire agricultural extent of Canada.
