Introduction to the GeoAI Foundation Model and Its Application

Recorded VCO
Abstract
This VCO presents work completed by Team 6 (GeoAwesome) project, which explored the geospatial artificial intelligence (GeoAI) foundation model and its applications during the I-GUIDE Summer School 2023. NASA and IBM have introduced a cutting-edge GeoAI Foundation Model called Prithvi-100M, which leverages satellite imagery data to provide insights into various geographical applications. This VCO introduces this novel foundation model with examples, such as crop classification, flooding, and burn scar detection. We also demonstrated how to fine-tune the model. More specifically, we enhance this model with the Normalized Difference Built-Up Index (NDBI) by employing Otsu's method to determine an optimal threshold for binary mask generation. This is an important task for urban planning and development analysis.
This VCO is part of a series showcasing work completed by participants at the I-GUIDE 2023 Summer School, Convergence Science in Action held in Boulder, CO in August 2023. As part of the program, 35 graduate students, postdocs, and early career scholars collaborated with I-GUIDE project members to develop novel solutions to complex problems that rely on computation- or data-intensive geospatial data science.
