What technology is used in GIS?
Artificial intelligence. Artificial intelligence is another rapidly evolving technology that has been applied to GIS projects in recent years. One important application for GeoAI is in planning urban infrastructure and tracking changes in an area over time.
What are the 5 layers of GIS?
