Research rationale and objective
Research overview
The framework links language-model reasoning to spatial layers, remote-sensing observations and GIS tools. Human validation, traceable evidence and clear uncertainty communication are treated as core design requirements.
Problem context and research need
Public-safety incidents and natural disasters are geographically complex events influenced by location, accessibility, population distribution, infrastructure, environmental conditions, and changing local circumstances.
GIS and GeoAI provide important analytical capabilities, but combining and interpreting multiple forms of spatial and contextual information may require specialist knowledge and several separate workflows.
Large language models can support natural-language interaction, synthesis, and contextual interpretation; however, general-purpose models may generate geographically inaccurate, unsupported, or overly general responses when they are not connected with reliable spatial evidence.
The research therefore explores a geospatially grounded approach in which geographic information and spatial analysis provide evidential support, while language models assist with interaction, contextual understanding, and communication.
Conceptual direction
Geographic grounding. Connect language-based interaction with verified geographic information, spatial relationships, and analytical evidence.
Responsible decision support. Support understandable interpretation while retaining traceability, uncertainty communication, human validation, and domain oversight.
