Abstract
This study focuses on the application of WebGIS in creating an online map depicting the current situation of outdoor Waste burning in Hoang Mai district, Hanoi capital. Results from field investigations and data analysis revealed 65 waste-burning sites within the research area, showcasing diversity in size, volume, and frequency of burning at these locations. The process of establishing GIS data and an online map applied the QGIS software and the Leaflet web platform, enhancing the location accuracy of waste points and providing an effective tool for conveying information to both the community and management authorities. The map offers an overview of the waste-burning situation and stimulates community awareness and consciousness regarding environmental protection.
