Layer: Active Floods in Canada (ID: 1)

Name: Active Floods in Canada

Display Field: product_file_name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Flood extent polygons representing active floods throughout Canada as monitored by Natural Resources Canada using satellite imagery for emergency response. In response to large flood events, Natural Resources Canada, for the provision of emergency geomatics services (NRCan), may be activated by Canada’s emergency management protocols. As new satellite imagery becomes available, NRCan will extract flood extent polygons and update the dataset in near real time (4 hours). This item contains the latest flood products generated in the past three days. For any data older than 72 hours, please refer to the Floods in Canada - Current Year entry. The flood products are generated and validated on a best effort basis. Various factors may affect the quality of the flood polygons. Those factors include but are not limited to: sensor type, image resolution, cloud coverage or limits to the flood polygon extraction method. In this layer, a symbology is applied to the flood polygons based on the underlying land use classification, when available, or is simply unclassified and shows the gross flood extent otherwise. Filter on date and Area of Interest (AOI) to view specific products. Time-enabled on Date UTC field. ".zip" file packages that contain the shapefile, PDF map, and ".kmz" of individual product items are available through the FTP links listed in the Package URL field.
