# Gratte Ciel 2009-2018 Temporal Building Tileset

A 3DTiles Tileset of the GratteCiel neighborhood from the years 2009-2018.

## Data treatment
The tileset was created from CityGML 2.0 datasets of the city of Villeurbanne available on:
- [data.grandlyon.com Villeurbanne 2009](https://download.data.grandlyon.com/files/grandlyon/imagerie/2009/maquette/VILLEURBANNE_2009.zip).
- [data.grandlyon.com Villeurbanne 2012](https://download.data.grandlyon.com/files/grandlyon/imagerie/2012/maquette/VILLEURBANNE_2012.zip).
- [data.grandlyon.com Villeurbanne 2015](https://download.data.grandlyon.com/files/grandlyon/imagerie/2015/maquette/VILLEURBANNE_2015.zip).
- [data.grandlyon.com Villeurbanne 2018](https://download.data.grandlyon.com/files/grandlyon/imagerie/2018/maquette/VILLEURBANNE_2018.zip).

An extract of these datasets was created using FME around the Gratte Ciel neighborhood of Villeurbanne.

Afterwards the cityGMLto3DTiles data pipeline was used to generate the tilesets, see [here](https://github.com/VCityTeam/UD-Reproducibility/tree/grattecieltemporal/Computations/3DTiles/GratteCielTemporal2009-2018) for the documentation.
