Desarrollo de una aplicación de streaming para el envío de imágenes meteorológicas desde un radar furuno manejado por el Inamhi

Abstract

This technical project shows the development of a web application for the National Institute of Meteorology and Hydrology of Ecuador (INAMHI) that allows the visualization of meteoro logical data of Quito, broadcast in real time. The transmitted meteorological data contains previously processed information of the in tensity of reflectivity received by the Furuno weather radar. This information can be displayed graphically, allowing to know the concentration of rainfall with a better resolution in time and coverage. The implementation includes the processing of radar data to extract the information stored in binary files from the reading and the application of image processing techniques in the decoded information to eliminate the parasitic echo of the signal and improve the quality of the image. For the transmission of information between the customer and the server, the WebSocket technology was implemented. This protocol allows a persistent and low latency bidirectional communication between the web application and the web server, facilitating the transfer of data in real time. The results of the implementation show that the web application is functional and meets the requirements requested by INHAMI. The application allows monitoring graphically the areas of the city where rainfall is occurring, improving the operational capabilities of this institution.
