# Roads

3D Roads of Lyon

## How to create those tilesets

The tileset was created with [Py3DTilers](https://github.com/VCityTeam/py3dtilers), an open source toolkit to create 3D Tiles out of various geometrical formats (OBJ, GeoJSON, IFC or CityGML), using the [GeojsonTiler](https://github.com/VCityTeam/py3dtilers/tree/master/py3dtilers/GeojsonTiler).

Roads are from open data and can be found online: 'TRONCON_DE_ROUTE' of [BD TOPO DÉPARTEMENT SHAPEFILE - RHÔNE](https://geoservices.ign.fr/telechargement) of IGN. Data was converted from Shapefile to GeoJSON with [QGIS](https://www.qgis.org/en/site/).

To install and use Py3DTilers, see online documentation: [installation](https://github.com/VCityTeam/py3dtilers?tab=readme-ov-file#installation-from-sources) & [usage](https://github.com/VCityTeam/py3dtilers?tab=readme-ov-file#usage).

The command used to create the tileset is:

```bash
geojson-tiler -i <path>/roads_rhone.geojson --height 0.5 --width LARGEUR -o Lyon_2018_Roads_TileSet
```
