3d-city-models

Python framework for integrating geospatial data, 3D city modeling, and urban simulation.

Reconstruction of LoD2 3D city models for urban flow simulations

Command-Line Interface (CLI) application for efficient and scalable generation of large-scale 3D building models.

3D modeling of urban forests based on LiDAR point clouds

A Model Context Protocol (MCP) server that gives AI assistants (Claude Code, Claude Desktop, and any MCP-compatible client) direct, natural language access to semantic 3D city models in CityGML managed within a 3DCityDB V5. Also includes an agentic Chatbot application using the MCP server with commercial or locally running LLMs.

The program automatically creates a tree cadastre from a point cloud.
