Pilot national scale maps of active deformation processes in Canada
The maps show a multiyear ground deformation rate caused by small-scale deformation processes in Canada, measured in meters per year. Horizontal-east and vertical deformation components were computed from data acquired on ascending and descending orbits. This horizontal-east/vertical 2D decomposition is approximate and assumes constant viewing geometry and the absence of horizontal-north deformation.In the line-of-sight (LOS) map computed from ascending orbit data, a negative signal approximately corresponds to either subsidence or eastward motion, while a positive signal corresponds to uplift or westward motion. In the LOS map computed from descending orbit data, a negative signal approximately corresponds to either subsidence or westward motion, while a positive signal corresponds to uplift or eastward motion.In the horizontal-east map, a negative signal corresponds to westward motion, while a positive signal corresponds to eastward motion. In the vertical map, a negative signal indicates subsidence, while a positive signal indicates uplift.The maps were calculated from Sentinel-1 Synthetic Aperture Radar data collected between 2017 and 2024 during the snow-free season. Interferometric analysis of Sentinel-1 data was performed using GAMMA Software (https://www.gamma-rs.ch), and the long-term deformation rate was computed with the Multidimensional Small Baseline Subset (MSBAS) Software Version 10 (https://doi.org/10.1080/07038992.2024.2424753) at the Canada Centre for Mapping and Earth Observation, Natural Resources Canada.Long-wavelength signals caused by postglacial rebound and tectonic motion were filtered to enhance the visibility of small-scale deformation processes, such as those originating from landslides and mining. Field studies have confirmed only a few of these processes to date. The maps are expected to contain processing artifacts, which will be addressed in future work.References:Samsonov, S.

Areas of high residency within the summer distribution of the beluga whale population
To identify areas of high residency, fine-scale tracking data from individual animals and coarser, short-term movement patterns of herds were analyzed. Individual radio-tracking was assessed from 2001 to 2005 and herd visual tracking was assessed from 1989 to 2008. Data was collected by two research teams: GREMM (Groupe de recherche et d’éducation sur les mammifères marins) and Fisheries and Océans Canada (DFO). Areas of high residency were determined using net displacement speed of herds and they were defined as adjacent cells where 50% of the herds travelled at or below a threshold speed.Areas of high residency do not represent the general distribution of the beluga whale and no association between these areas and specific biological functions could be established. The exact delimitation of these areas can change according to the definition criteria used in the analysis. Therefore, the marginal cells are not necessarily indicative of lower habitat quality.Data source:Lefebvre, S., Michaud, R., Lesage, V. and Berteaux, D. (2012).

Motor Vehicle Prohibition Regulation Areas
These polygons represent areas across the Province where motor vehicles are prohibited or restricted year round or seasonally. These areas were created as a visual representation of the Wildlife Act Motor Vehicle Prohibition Regulations. Under the Motor Vehicle Prohibition Regulation of the provincial Wildlife Act, motor vehicle use on crown land in B.C. may be prohibited or restricted. This data is a summary of the Motor Vehicle Prohibition Regulations, and is intended for general information purposes only. Where there is a discrepancy between these maps and the Regulations, the Motor Vehicle Prohibition Regulations are the final authority. Motor Vehicle Prohibitions (MVP) are put in place for a variety of reasons. MVPs can be used to: * protect habitat * reduce disturbance and displacement of wildlife * provide areas for hunters on foot, bike or horseback to hunt without motorized vehicles present * reduce hunter harvest while maintaining hunting opportunity Motor vehicles include but are not limited to: * vehicles * ATVs/UTVs * snowmobiles * motorcycles * electric bikes For full definitions and detailed regulations, visit the Motor Vehicle Prohibition Regulations website (available under Related Links). There are 2 types of motor vehicle restrictions under the Wildlife Act, and all types can be seasonal or year-round. 1. **Motor Vehicle Closed Area** (formerly referred to as Access Management Areas (AMAs): Prohibits the use or operation of a motor vehicle and e-bike. These prohibitions can be for all motor vehicles, or specific to ATVs/e-bikes or snowmobiles. 2. **Motor Vehicle Hunting Closed Area**: The operation of motor vehicles and e-bikes to hunt, transport wildlife, transport equipment and supplies which are intended for or in support of hunting, or transport hunters to and from the location of wildlife is prohibited. These prohibitions can apply to all motor vehicles, or be specific to ATVs/e-bikes or snowmobiles.

AAFC Infrastructure Flood Mapping in Saskatchewan 20 centimeter colour orthophotos
The AAFC Infrastructure Flood Mapping in Saskatchewan 20 centimeter colour orthophotos is a collection of georeferenced color digital orthophotos with 20 cm pixel size. The imagery was delivered in GeoTIF and ECW formats. The TIF and ECW mosaics were delivered in the same 1 km x 1 km tiles as the LiDAR data, and complete mosaics for each area in MrSID format were also provided. The digital photos were orthorectified using the ground model created from the DTM Key Points. With orthorectification, only features on the surface of the ground are correctly positioned in the orthophotos. Objects above the surface of the ground, such as building rooftops and trees, may contain horizontal displacement due to image parallax experienced when the photos were captured. This is sometimes apparent along the cut lines between photos. For positioning of above-ground structures it is recommended to use the LiDAR point clouds for accurate horizontal placement.
