Mapping of the road sections of Lorient Agglomeration

Dataset identifying road sections on the territory of the agglomeration. The database allows different themes including the classification of tracks, speeds etc. **Collection context** This data was constructed on the basis of bases of various origins and different qualities: - the DGFiP-labelled cadastre - orthophotographs at 20cm - different layers of in-house data - deliberations of municipal roads **Method of collection** Regarding the construction of geometry, the preferred reference is the cadastre (because this background is very widely used). However, in addition, we rely on the most recent ortho that we have because it better reflects the real situation on the ground. **Attributes** | Field | Alias | Type | | --- | --- | --- | | `id _tronçon` | | `int4` | | `id _source` | | `int4` | | `id _modif _tronçon` | | `int4` | | `lib _modif` | | `varchar` | | `lib _source` | | `varchar` | | `lib _dep` | | `varchar` | | `insee` | | `varchar` | | `id _lieudit _d` | | `int4` | | `name _ld _d` | | `varchar` | | `id _lieudit _g` | | `int4` | | `name _ld _g` | | `varchar` | | `id _quartier _d` | | `int4` | | `name _quartier _d` | | `varchar` | | `id _quartier _g` | | `int4` | | `name _quartier _g` | | `varchar` | | `id _cl _admin` | | `int4` | | `lib _cl _admin` | | `varchar` | | `id _domaniality` | | `int4` | | `lib _domaniality` | | `varchar` | | `id _circu` | | `int4` | | `lib _circu` | | `varchar` | | `id _typoroute` | | `int4` | | `lib _typoroute` | | `varchar` | | `id _ user` | | `int4` | | `lib _ user` | | `varchar` | | `natvoi _cad` | | `varchar` | | `id _voie _d` | | `int4` | | `name _voie _d` | | `varchar` | | `id _voie _g` | | `int4` | | `name _voie _g` | | `varchar` | | `id _extr _deb` | | `int4` | | `id _extr _fin` | | `int4` | | `nb _voie` | | `int4` | | `length` | | `int4` | | `width` | | `int4` | | `speed` | | `int4` | | “date _modif“ | | “date“ | | `grand _axe` | | `int4` | | `id _competencies` | | `int4` | | `lib _competencies` | | `varchar` | | `comriv` | | `varchar` | | `name _breton` | | `varchar` | | `num _max` | | `int4` | | `num _min` | | `int4` | | `level` | | `int4` | | “date _crea“ | | “date“ | | `old _idtron` | | `int4` | | `name _com` | | `varchar` | | `other _nom` | | `varchar` | For more information, see [the Isogeo catalogue metadata](https://open.isogeo.com/s/0bd17a2a330842c68ec4a412d1df6824/AiCyPK6W8fg012l-vHV0s5tPry5b0/r/ea62f5791c254c1bad3a85bcb19793c7).
