GreenEye: mapeamento dos locais de descarte indevido de lixo por meio de um SIG

Abstract

The improper disposal of urban solid waste represents a chronic challenge for environmental management, resulting in pollution and risks to public health. The lack of systematized tools for the continuous monitoring of these waste hotspots hinders strategic decision-making and the efficient allocation of resources. This work presents the proposal and implementation of "GreenEye," a collaborative Web Geographic Information System (WebGIS) whose objective is to map and analyze locations of irregular waste disposal. The methodology adopted involved a literature review on waste management and geotechnologies, and the definition of a software architecture based on the client-server model, using Node.js with Express for the REST API, React with Leaflet for the map interface, and PostgreSQL with the PostGIS extension for the storage and analysis of geographic data. As an expected result, the platform allows citizen engagement through georeferenced reports and provides public managers with a tool for spatial analysis, such as the identification of critical areas (hotspots), optimizing inspection and cleaning actions. This project contributes an applicable technological solution for the modernization of solid waste management, promoting transparency and collaboration between public authorities and society.
