Welcome

Dr. Yu is currently an Assistant Professor in the School of Geography at Nanjing Normal University. His research primarily focuses on 3D GIS, Virtual Geographic Environments, 3D City Modeling, and Geographic Information Services. His work specifically addresses challenges related to geographic modeling and simulation in the context of 3D GIS.

Dr. Yu has studied at renowned institutions such as the School of Remote Sensing Information Engineering at Wuhan University, the Urban Analysis Lab at National University of Singapore. He has published numerous papers in top-tier journals, including IJGIS, JAG, and NHESS, and has been invited to deliver lectures on 3D GIS, geographic modeling, and virtual geographic environments. He maintains strong collaborative relationships with several governmental organizations and leading industry enterprises. As a key researcher, he contributed to development the development of the Open Geospatial Engine, a cloud-native geospatial analysis platform. Additionally, he contributed to the development of the OGC TrainingDML specification and has participated in the formulation of several National Standards of China. Currently, he is a member of the OpenGMS team.

Towards an integrated approach for managing and streaming 3D spatial data at the component level in spatial data infrastructures

we developed a generic conceptual model suitable for component-level management of diverse 3D spatial data in SDIs and discussed the design rationales and key considerations underlying the model.

Bidirectionally Greedy Framework for Unsupervised 3D Building Extraction from Airborne-based 3D Meshes

We prpoased a novel bidirectionally greedy framework to extract fine-grained 3D building models from photo-realistic 3D meshes in an unsupervised manner.

Unsupervised Ground Filtering of Airborne-based 3D Meshes Using a Robust Cloth Simulation

We propose a robust cloth simulation method for filtering ground primitives from photo-realistic 3D meshes. The method can accurately decompose the realistic 3D meshes into the 3D ground and non-ground 3D model, and it is robust for different landscapes and is not impacted by vertex density and noise.

A Virtual Geographic Environment for Dynamic Simulation and Analysis of Tailings Dam Failure

Building upon the physical properties of tailings flow, we developed a VGE platform for dam failure disaster evolution simulation, which can simulate and predicts the route and disaster-causing range of tailings after a failure, and visualize the results in a three-dimensional, dynamic and interactive manner.
