Nathan McEachen
Nathan McEachen is the founder, CEO, and CTO of TerraFrame, which specializes in supporting ministries of health and national spatial data infrastructures by building geospatial knowledge infrastructures with open-source GIS, remote sensing, and interoperability solutions. He obtained his master’s degree in computer science from Colorado State University in the United States. He is academically published in the fields of software testing, model-driven engineering, disease intervention, and spatial information sciences. Nathan is involved with the Open Geospatial Consortium and HL7 to help align standards development, enabling more automated data integration across sectors to bring geospatial awareness to LLMs.
Sessions
Attendees will build two complementary approaches for enabling geospatial awareness in LLMs: Geo-GraphRAGs for analyzing networks of features and DGGS-based methods for integrating aggregate and statistical data, and how they work together.
While LLMs excel at synthesizing text, they lack geospatial awareness and cannot reason over spatial networks. This talk demonstrates how Geo-GraphRAG and DGGS, grounded in open standards, enable geospatial reasoning with transparent, traceable results.
