The level of detail (LOD) concept of the OGC standard CityGML 2.0 is intended to
differentiate multi-scale representations of semantic 3D city models. The concept is in …

CityGML (City Geography Markup Language), the OGC (Open Open Geospatial
Consortium) standard on three-dimensional (3D) city modeling, is widely used in an …

This article presents a spatial cognition analysis technique for automated urban building
clustering based on urban morphology and Gestalt theory. The proximity graph is selected to …

The simplification of three‐dimensional (3D) building models to improve rendering efficiency
has gained widespread attention. To maintain the model's overall appearance features …

Geographic data visualization is an important research area of Web Geographic Information
System (GIS). Owing to the detailed subassemblies and exhaustive knowledge database …

A high-fidelity and real-time rendering urban building model was implemented through the
simplification of 3D building groups. An approach to simplify a single 3D building has been …

To visualize large urban models efficiently, this paper presents a framework for generalizing
urban building footprints and facade textures by using multiple Gestalt rules and a graph-cut …

The simplification of 3D building models to effectively reduce model complexity and improve
rendering efficiency is an important component of 3D GIS. To reduce the data volume while …

What is the best way to design with greenery? What are the benefits of selecting one species
of tree over another, and placing it at Point A instead of Point B? Will it cost more than the …
