# Lyon 1er 2015 20 Building Tileset

This dataset is used by the [UD-Demo-Graph-SPARQL](https://github.com/VCityTeam/UD-Demo-Graph-SPARQL) demo. It features 20 buildings from the 1st district of Lyon. In particular the batch table of the tileset contains the original `gml:id` of each building object.

## Data treatment
The tileset was created from a CityGML 2.0 dataset of the 1st district of Lyon available on [data.grandlyon.com](https://data.grandlyon.com/jeux-de-donnees/maquettes-3d-texturees-2015-communes-metropole-lyon/donnees).
This dataset was cut down by hand to a smaller dataset of 20 buildings.
Afterwards the CityTiler function of the [Py3DTilers](https://github.com/VCityTeam/py3dtilers) data pipeline was used to generate a 3DTiles tileset.
