Automatic Tree Cadastre

Description

This project was developed as part of the master thesis "Automated Generation of a Tree Cadastre From Point Clouds in Different Urban Environments". The full-text of the thesis was published via MediaTUM and can be found here. If you use this code or my master thesis please cite this document:

The program automatically creates a tree cadastre from a point cloud. The tree cadastre resulting from the automated workflow is subsequently available as a tree parameter list in a CSV file and also as a CityGML file. In the CityGML file, the trees also have a geometric representation in the form of a cylinder-sphere model based on the respective tree parameters. For more details and example results please have a look at the mastersthesis.

Getting started

• you will need to install:
  • Python 3.10 (3.11 will not work because Open3D needs version 3.10)
  • FME 2022.2.5 (get FME) with a license
  • VS Code
  • Microsoft Visual C++ 14.0 or greater. Get it with Microsoft C++ Build Tools.
• you will need pointcloud data
• open your favourite terminal
• install pipenv: pip install pipenv
• clone this git repository: git clone --recursive https://github.com/SabineZa/Automatic_Tree_Cadastre.git
• open VS Code in the automatic-tree-cadastre folder
• open a new terminal in VS Code
• install all needed packages from the Pipfile: pipenv install
• set all parameters and file paths according to your data in main.py (or main.ipynb)
• run main.py (or main.ipynb) and enjoy the results in the output folder
  • either run main.py in the terminal: pipenv run python main.py
  • or switch to the automatic-tree-cadastre environment in VS Code and run main.py or main.ipynb from there

If you don't have a FME-license you can nevertheless use the code and create a tree cadastre out of your pointclouds. The only drawback will be that you can't create a geometric representation of the trees in CityGML. For that you just have to disable the correspnding lines of code.
