Spring 2020 flood mapping

#Données linked to the monitoring of the 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);
  • Limits of the extent of open waters derived from Sentinel1 satellite images, generated by Dromedaire Géo-Innovations (WMS web service and download);
  • Sentinel-1 radar satellite image from April 4, 2020 processed by the firm Dromedaire Géo-Innovation which presents a map of the ice cover and possibly flooded areas (with or without ice) for the Chaudière River sector, where ice jams caused flooding (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 of April 8, 2020 in the visible and near infrared in 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).
