Tobler's First Law in GeoAI

Presenter: Dr. Wenwen Li (Arizona State University)
Moderator: Dr. Yongmei Lu (Texas State University)


AbstractGeoAI, or geospatial artificial intelligence, is powerful to solve complex geospatial problems. Leveraging recent breakthroughs in deep learning and advanced computing, GeoAI enables scalable processing and intelligent analysis of geospatial big data. A core issue is how to make AI integral to the geospatial science framework. This presentation will introduce a new GeoAI model that enables automated spatial object detection, especially of natural features, in a weakly supervised manner. It will also cover discussions about the enablement of spatially explicit machine learning by integrating Tobler’s First Law of Geography; as well as the generalizability of the GeoAI model, in detecting both manmade and natural features on the surface of the Earth and other planets.
