By Shahabuddin Amerudin

Geospatial Artificial Intelligence (GeoAI) is a specialized field that combines geospatial data, which includes geographic information such as location, coordinates, and spatial relationships, with artificial intelligence (AI) techniques to extract valuable insights, patterns, and predictions from spatially referenced data. In essence, GeoAI involves the application of AI algorithms and methodologies to geospatial data to solve complex problems and enhance decision-making in various domains.

Key Components of GeoAI

1. Geospatial Data: GeoAI relies on various types of geospatial data, such as satellite imagery, GPS coordinates, maps, geographic databases, and sensor data. These data sources provide the spatial context necessary for understanding and analyzing patterns and phenomena.
2. Artificial Intelligence Techniques: AI techniques employed in GeoAI include machine learning, deep learning, natural language processing, computer vision, and other AI subfields. These techniques help process and analyze geospatial data to extract meaningful information.
3. Data Fusion: GeoAI often involves the integration of multiple data sources, which may include satellite imagery, sensor data, and demographic information. Data fusion techniques are used to combine these sources and generate more accurate and comprehensive insights.

Applications of GeoAI
