Morphology-Guided Cross-Task Coupling for Joint Building Height and Footprint Estimation
Jinzhen Han, JinByeong Lee, Jisung Kim +1
Building height (BH) and building footprint (BF) jointly describe the vertical and horizontal extent of the built environment and are required inputs for urban climate, disaster-ri…
GISclaw: A Comprehensive Open-Source LLM Agent System for Realistic Multi-Step Geospatial Analysis
Jinzhen Han, JinByeong Lee, Yuri Shim +2
Most LLM-driven GIS assistants solve narrow single-step tasks tightly coupled to proprietary platforms such as ArcGIS or QGIS, limiting their use for the multi-step, cross-format p…
GeoFormer: A Lightweight Swin Transformer for Joint Building Height and Footprint Estimation from Sentinel Imagery
Han Jinzhen, JinByeong Lee, JiSung Kim +3
Building height (BH) and footprint (BF) are fundamental urban morphological parameters required by climate modelling, disaster-risk assessment, and population mapping, yet globally…
FireSenseNet: A Dual-Branch CNN with Cross-Attentive Feature Interaction for Next-Day Wildfire Spread Prediction
Jinzhen Han, JinByeong Lee, Hak Han +2
Accurate prediction of next-day wildfire spread is critical for disaster response and resource allocation. Existing deep learning approaches typically concatenate heterogeneous geo…
A Lightweight LLM Framework for Disaster Humanitarian Information Classification
Han Jinzhen, Kim Jisung, Yang Jong Soo +1
Timely classification of humanitarian information from social media is critical for effective disaster response. However, deploying large language models (LLMs) for this task faces…
