Near-real time rainfall monitoring in the Caraga region, Mindanao, Philippines using openlayers api and javascript

By Edsel Matt O. Morales, Jojene R. Santillan, Meriam Makinano-Santillan

ABSTRACT:

We developed an online tool for near-real time monitoring of rainfall intensity and accumulated rainfall in various localities in the Caraga Region, Mindanao, Philippines. The web map interface was built using Openlayers API where the locations of all rain gauge stations installed by ASTI DOST are plotted. For each station, a JavaScript is used to extract and analyze 24-hour rainfall data from the ASTI DOST. Based on extracted data, the current rainfall intensity at each rain gauge location is plotted on the web map according to a color scheme that signifies no rainfall, light, moderate, heavy, intense, and torrential rainfall intensities. Clicking on the points of a rain gauge will also show a graph of the rainfall intensities and accumulated rainfall in the last 24 hours. The application is available at http://rainmonitoring.csulidar1.ccgeo.info which can be utilized by Local Government Units (LGUs) and residents of Caraga Region, for rapid rainfall monitoring and as a tool for flood disaster preparedness.
