Measurement of the flow and level stations of the partners of the Ministry of Public Security (MSP) from the flow-level application (ADN) developed at the MSP. The flows and levels make it possible to automatically monitor open water floods in rivers, watersheds and lakes where hydrometric stations are installed based on pre-established impact thresholds. Other waterways that do not have such instruments are also monitored by municipal and government authorities. In order to quickly visualize the sectors most at risk of flooding, watersheds and administrative regions, the application displays the color of the station with the highest threshold by default. Purpose: Integrate into a single application linked to web services (e.g. WMS, WFS) all the data from the hydrometric stations of the MSP partners. This data is imported in real time in order to monitor floods and monitor low water levels. Data from the following partners are integrated into the application and web services: Centre d'expertise du Québec, Meteorological Service of Canada, Canadian Hydrographic Service, Hydro Météo, Chaudière River Monitoring System, and the USGS.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
