CityGML

CityGML is an open data model and file format used to represent and share detailed 3D city and landscape information digitally. It captures the geometry, appearance, and semantics of urban features like buildings, roads, parks, and terrain, allowing for accurate visualizations and analyses. Think of it as a standardized digital blueprint of a city, enabling planners, architects, and developers to work with detailed, realistic models for planning, simulation, and management of urban environments efficiently and consistently.
