# #Données linked to the monitoring of 2020 floods in Quebec ## #Liste of available data: * Location of flood events since April 2, 2020 (WMS web service); * Municipalities affected by flood events since April 2, 2020, updated in real time according to the presence of events (WMS web service); * Open water extent limits derived from Sentinel1 satellite images, generated by Dromedary Géo-Innovations (web service) WMS and download); * Sentinel-1 radar satellite image from 4 April 2020 processed by the firm Geo-Innovation camel that presents a map of the ice cover and possibly flooded areas (with or without ice) for the Chaudière River sector, where ice jams caused floods (resolution: 10m). Possible flooded areas (with or without ice) were identified from a comparative analysis between two Sentinel-1 images from 4 April and 23 March 2020 acquired in the same orbit; * Sentinel-2 satellite image from 8 April 2020 in the visible and near infrared in the visible and near infrared on the Lac Saint-Pierre sector (WMS web service and download). All data can be viewed on an interactive map based on IGO2. ## #Note: The Sentinel-1 and Sentinel-2 satellite images are distributed in open data by the European Space Agency (ESA) and were processed by the firm Dromadaire-Geo-Innovations.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The purpose of this dataset is to locate the events related to the spring 2023 floods recorded by the Deputy Directorate General of Operations of the Ministry of Public Security. All data is available on an interactive map and available as WMS and WFS web services. > To monitor the status of watercourses live, please refer to the [Vigilance - Flood Monitoring] application (https://vigilance.geo.msp.gouv.qc.ca/) ### List of available data: * **List of available data: * **Open water polygons derived from satellite data**: extent limits of open water derived from radar satellite images**: extent limits of open water derived from radar satellite images**: extent limits of open water derived from radar satellite images**. Location of flood events since April 14, 2023**: points locating approximately the flood events recorded by the Operations Directorate of the Ministry of Public Security as of April 14, 2023 (derived from the dataset [Civil Security Events] (https://www.donneesquebec.ca/recherche/dataset/evenements-de-securite-civile)). * **Municipalities affected by flood events since April 14, 2023**: cartographic representation of municipalities affected by flooding events since April 14, 2023. * **Sentinel-2 satellite image**: satellite image covering sectors flooded and presented in the form of a colored compound using short band infrared, near infrared and red wavelengths. ## #Note: Satellite acquisitions for the RADARSAT Constellation Mission (RCM) are planned in collaboration with Natural Resources Canada. The images obtained are processed by the emergency geomatics services of Natural Resources Canada as soon as possible and then the open water polygons are distributed as open data on Data Canada and on Data Quebec. Other optical or radar acquisitions may have been obtained by the Ministry of Public Security (MSP) from private suppliers. The Sentinel-1 and Sentinel-2 acquisitions released in open data by the European Space Agency (ESA) were processed by the Dromedaire Géo-Innovations firm.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
