Paper Summary

A new data model called UKRM was created to improve how 3D geographic information is represented in GIS systems. By combining different types of data representation and structures, UKRM can better handle complex spatial objects and meet various user needs. This model outperformed existing models like IFC and CityGML in describing both regular and irregular spatial objects.
