Chat2Geo is a web application built on Next.js 15 that provides a ChatGPT-like chat interface for performing remote sensing-based geospatial analysis. It leverages Google Earth Engine to process and analyze various remote sensing datasets in the backend. Users can upload their own vector data, run advanced geospatial queries, and integrate with an AI assistant to complete tasks such as land cover mapping, change detection, and air pollutant monitoring. By combining geospatial analysis with non-geospatial/textual information, this product offers a powerful and practical Knowledge Retrieval Augmented Generation (RAG) workflow. It inherits most of the building blocks of the GRAI 2.0 application developed by GeoRetina and is continuously updated to meet community needs.
