Effective AI for good initiatives critically depend on high-quality, readily available information, especially concerning vulnerable global communities often unrepresented in digital maps. The discussion emphasizes how multi-layered maps, integrating topographical, infrastructural, seasonal, and real-time data, serve as essential humanitarian tools. Advances in satellite imagery, drone technology, mobile devices, and crowdsourcing platforms like OpenStreetMap are democratizing data collection, making previously invisible areas mappable. Supported by cloud infrastructure and open data policies, this approach enables a powerful system for addressing challenges from disaster response to healthcare and environmental protection, ultimately promoting a more equitable world.
