Projects

	Multi-Layer Raster Coupling with Directional Constraint Coding: A Discrete Spatial Modeling Method for UAV 3D Path Planning ESRI Cup / GIS Algorithm Design A discrete spatial modeling method using directional constraint coding and multi-layer raster coupling for urban low-altitude UAV 3D path planning, winning first prize in the Geographic Design track of the ESRI China National GIS Software Development Competition.
	LinkTool v1.0 — A Natural-Language-Driven GIS Analysis Agent Based on the Model Context Protocol GIS Agent / MCP Plugin An ArcGIS Pro agent-plugin prototype based on large language models and the MCP protocol, exploring natural-language access to commonly used spatial-analysis tools.
	Macroscopic Simulation Analysis of Nitrogen and Phosphorus Loss Patterns Innovation Training / Agricultural NPS Pollution A university-level innovation training project exploring a 'plot-watershed-model' analysis approach that combines LOADEST, InVEST, machine learning, and GIS for agricultural non-point source pollution risk assessment.
	Village-Scale Reality 3D Modeling with UAV Photogrammetry — A Case Study of Beigen Village, Zhaoqing Geographic information engineering fieldwork / Digital village A reality 3D model and village geodatabase created from UAV oblique and nadir imagery, road and POI field surveys, and GIS processing for village visualization and spatial analysis.
	Accurate Step Counting and Real-Time Step Length Estimation Based on Pedestrian Single-Step Acceleration Area Features Surveying and Mapping Competition / Scientific Paper Track A 2026 Scientific Paper Track study that uses single-step acceleration area features for both step detection and step-length estimation, providing gait-event and per-step displacement estimates for smartphone PDR.
	Education for a Rising Bay Area — A Spatial Study of Education through the Development Story of the Greater Bay Area ESRI Cup / Story Map A story-map project linking individual education experiences with multi-source spatial data to examine school siting and educational-resource allocation across the Guangdong–Hong Kong–Macao Greater Bay Area.
	Reducing Carbon, Enhancing Aroma — Circular Farming and Intelligent Pest Regulation for Zijin Cicada Tea Challenge Cup and Energy Conservation & Emission Reduction Competition / Low-carbon agriculture A proposed system combining waste co-composting, intelligent leafhopper monitoring, and pest-informed fertilization, with image recognition and GIS used to assess low-carbon production pathways for Zijin cicada tea.
	Reflections of Didou — Revitalizing an Old Cinema as a Township Living Room Challenge Cup / Rural renewal and cultural-tourism planning A renewal proposal for an old cinema in Didou Town that preserves its historic character and plans spaces for meetings, exhibitions, fitness, heritage experiences, and local-product promotion.
