Mapping of Lorient Agglomeration track sections

Description

As part of the operation of its Geographical Information System, based on Intergraph products (Hexagon AB), the GIS Mission of Lorient Agglomeration wanted to finalise the implementation of its network of channels type BD Voies Adresses, throughout its territory for use for different applications. These data will constitute a very useful database of references to the services and municipalities of Lorient Agglomeration. The uses will be diverse: * Integration into the GIS (Base PostGIS); * Use in the Intranet, Extranet, Lorient Agglomeration website; * For business applications; * Realisation of city plans etc. Lorient Agglomeration has a “paths” repository. It is a wireline (cuts) and punctuals that allow at least: * Identification of track axes (denomination, domaniality,...), * Unique ID; * The assessment of the line of pathways; * Addresses * Annotation of path names. **Collection context** For this service, the databases available are of different origins and of different qualities: the DGFiP labeled cadastre, an ORTHO 201 020 cm, and various layers of data made internally. GEOMATECH has carried out this basic service. Since the GIS mission carries out regular updates. **Collection method** Regarding the geometry and geography of the graphic data, the reference frame to be preferred will be the cadastre (except in case of significant difference with the ortho, which in this case will be priority), because this background is widely used for all other applications. However, in addition (parcellar not clear, non-existent path to the cadastre, access straps, turnarounds,...), we will favour ortho for the geometry of the axes because it better reflects the real occupation of the right-of-way on the ground. But having several sources will generally be an interesting element to ensure a very good level of completeness (do not forget anything) and will also serve for the expected information. Continuous update with the different ortho vintages. **Attributes** | Field | Alias | Type | | — | — | — | | ‘grand_axe’ | Designed for carto. 0: normal axis; 1: large Axis (Framework) | ‘int4’ | | ‘nb_channel’ | Number of lanes that designate the road strip assigned to a vehicle line(1-2 — 3) | ‘int4’ | | ‘id_extr_deb’ | FK address_ref.extremite id_extr (extremity of departure) | ‘int4’ | | ‘id_voie_g’ | FK address_ref.voie_txt id_voie (id_voie_g) | ‘int4’ | | ‘id_quartier_d’ | FK ref_admin.quartier id_diartier (id_diartier_d) | ‘int4’ | | ‘date_crea’ | Auto Calculation Date Modified (Do not complete) | ‘date’ | | ‘width’ | Track width (Full field) | ‘int4’ | | ‘old_idtron’ | only if the trunk is replaced; Old id_troncon for MAJ external scheme | ‘int4’ | | ‘id_domanialite’ | FK ref_address.domanialite id_domanialite | ‘int4’ | | ‘id_voie_d’ | FK address_ref.voie_txt id_voie (id_voie_d) | ‘int4’ | | ‘id_typoroute’ | FK ref_address.type_route id_typoroute | ‘int4’ | | ‘id_circu’ | FK address_ref.circulation id_circu | ‘int4’ | | ‘id_lieudit_d’ | FK ref_admin.lieudit id_lieudit (id_lieudit_d) | ‘int4’ | | ‘id_lieudit_g’ | FK ref_admin.lieudit id_lieudit (id_lieudit_g) | ‘int4’ | | ‘length’ | Calculation auto trigger function | ‘int4’ | ‘int4’ | | ‘id_modif_troncon’ | FK address_reftype_modif id_modif (id_voie_troncon) | ‘int4’ | | ‘id_cl_admin’ | FK ref_admin.cl_admin id_cl_admin | ‘int4’ | | ‘id_quartier_g’ | FK ref_admin.quartier id_quartier (id_diartier_d) | ‘int4’ | | ‘id_source’ | FK address_ref.source id_source | ‘int4’ | | ‘speed’ | max track speed (Full field) | ‘int4’ | | ‘date_modif’ | Auto Calculation Date of Creation (Do not complete) | ‘date’ | | ‘id_troncon’ | Single auto num (primary key) | ‘serial,PrimaryKey’ | | ‘id_extr_fin’ | FK address_ref.extremite id_extr (extremity of end) | ‘int4’ | | ‘level’ | -1-0 — 1 etc (0 ground level) | ‘int4’ | | ‘id_competences’ | FK ref_address.competence id_competences | ‘int4’ | For more information, see [the metadata on the Isogeo catalog](https://open.isogeo.com/s/0bd17a2a330842c68ec4a412d1df6824/AiCyPK6W8fg012l-vHV0s5tPry5b0/r/0526c3c1d03147ccab54c5791f41851a).
