3dbag-scripts

Small scripts for various functionalities related to 3DBAG data

From 3DBAG-API to a city.json file

Script: api_to_cityjson.py

This script fetches a single building from the 3DBAG API and saves it directly in a CityJSON file.

It requires an installation of cjio. Preferably in a virtual environment you can install cjio with:

pip install cjio

Then, in the script, you need to substitute the BUILDING_ID with the id of the building you want to fetch.

Then you can run the script from your terminal with:

python3 api_to_cityjson.py

The script will first download the city.jsonl file and then convert it to city.jsonl, using as filename the BUILDING_ID

Download 3DBAG Tiles

The script downloads 3DBAG tiles in the formats obj, cityjson and gpkg. You can specify the output directory with the --outdir flag. If not specified, the files will be downloaded in the current directory. You can specify the bounding box with the --bbox flag in the format xmin, ymin, xmax, ymax. If not specified, the script will download all tiles. You can specify the formats you want to download with the flags --obj, --cityjson and --gpkg. If not specified, the script will download all formats.

Examples:

Download all tiles in all formats in a specific directory:

python3 tile_downloader.py --outdir /path/to/directory

Download tiles within a bbox in obj formats in the current directory:

python3 tile_downloader.py --bbox 84000 477000 86000 478000 --obj
