Spring 2019 flood mapping

Spring 2019 flood mapping # #Données related to the monitoring of the 2019 floods in Quebec __Attention: water extent data is a near real-time interpretation of satellite data; they were produced in operational mode and are provided as is without exhaustive validation. The product may contain errors, especially in urban areas.__ ## #Liste of available data: * the monitoring of flood and landslide events between April 14, 2019 and May 28, 2019 in geolocated points (web service and download), * municipalities affected by flood events between April 14, 2019 and May 28, 2019, updated in real time with the event layer (web service); * the boundaries of extent of open waters generated by Natural Resources Canada, derived from data Radarsat 2 satellites or other radar satellites and those generated by Dromedaire Géo-Innovations, derived from Sentinel satellite data (web service and download), * flood limits for the Chaudière River sector derived from heliborne data (web service and download) * satellite images in the visible and near infrared on the most severely affected areas (web service and download when possible). * acquired oblique images on April 29 on the Ottawa River and the greater region of Montreal as part of the National Aerial Surveillance Program (link to the application of the Federal Government Operations Center) All data are also available on an interactive map based on IGO2. ## #Note: Radarsat-2 satellite acquisitions are planned in collaboration with Natural Resources Canada. Access to radar satellites from other Canadian space agencies is possible thanks to the activation of the International Space and Major Disaster Charter. It is activated by Public Safety Canada. The images obtained via the international charter are processed by the emergency geomatics services of Natural Resources Canada as soon as possible and then the open water polygons are disseminated 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 firm Dromadaire-Geo-Innovations.**This third party metadata element was translated using an automated translation tool (Amazon Translate).** 2025-02-12 Government and Municipalities of Québec outils_securite_civile@msp.gouv.qc.ca Form DescriptorsNature and EnvironmentScience and Technology Sentinel 2 Lac St-Pierre image from April 21GeoTIF https://geoegl.msp.gouv.qc.ca/partageDQ/inondations2019/S2_20190421T154819_LAC_ST_PIERRE.tif Sentinel 2 St-Laurent and Outaouais image from May 6GeoTIF https://geoegl.msp.gouv.qc.ca/partageDQ/inondations2019/S2_20190506T154911_Outaouais_Stlaurent.tif 2019 Flood MapHTML https://geoegl.msp.gouv.qc.ca/igo2/apercu-qc/?context=inondation2019 Oblique images of the 2019 flood - Outaouais and MontrealHTML http://arcg.is/0LLzr8 Original metadata (https://www.donneesquebec.ca)HTML https://www.donneesquebec.ca/recherche/fr/dataset/df99bb67-317c-435b-8f9a-50de5fa9729a WorldView image: Lac St Pierre from 23 AprilJPG https://diffusion.mern.gouv.qc.ca/diffusion/RGQ/Matriciel/Satellite/Local/BDSQ/JP2/ Open water polygons derived from satellite dataSHP https://geoegl.msp.gouv.qc.ca/partageDQ/inondations2019/msp_inondations2019_eaulibre_20190521_1148.zip Polygons of extent of floods in the Chaudière River derived from aerial dataSHP https://geoegl.msp.gouv.qc.ca/partageDQ/inondations2019/msp_inondations2019_zone_inondee_chaudiere.zip Flood events - spring 2019SHP https://geoegl.msp.gouv.qc.ca/apis/wss/complet.fcgi?service=wfs&version=1.1.0&request=getfeature&typename=vg_observation_v_inondation14avril2019_wmst&outputformat=shp Municipalities affected by floodsSHP https://geoegl.msp.gouv.qc.ca/apis/wss/complet.fcgi?service=wfs&version=1.1.0&request=getfeature&typename=vg_observation_inondation_14avril2019_mun_tout_v&outputformat=shp Web service (WFS) for points and polygonsWFS https://geoegl.msp.gouv.qc.ca/ws/inondation2019.fcgi?SERVICE=wfs&request=GetCapabilities Tracking Data Mapping Web Service (WMS)WMS https://geoegl.msp.gouv.qc.ca/ws/inondation2019.fcgi?request=getcapabilities&service=wms&layers=INONDATION2019&legend_format=image/png&feature_info_type=text/plain Tracking Data Mapping Web Service (WMS)WMS https://geoegl.msp.gouv.qc.ca/ws/inondation2019.fcgi?request=getcapabilities&service=wms&layers=INONDATION2019&legend_format=image/png&feature_info_type=text/plain 2017 and 2019 Flood Imagery Web Service (WMS)WMS https://servicesmatriciels.mern.gouv.qc.ca/erdas-iws/ogc/wms/Imagerie_MERN?service=WMS&request=GetCapabilities&version=1.3.0&layers=Evenements-Securite-Civile&legend_format=image/png&feature_info_type=text/plain 2017 and 2019 Flood Imagery Web Service (WMS)WMS https://servicesmatriciels.mern.gouv.qc.ca/erdas-iws/ogc/wms/Imagerie_MERN?service=WMS&request=GetCapabilities&version=1.3.0&layers=Evenements-Securite-Civile&legend_format=image/png&feature_info_type=text/plain
