Outlines of French boroughs from OpenStreetMap
收藏资源简介:
Exports of the French administrative division at the level of the arrondissements resulting from OpenStreetMap produced in the vast majority from the cadastre. This data comes from crowdsourcing carried out by the contributors to the OpenStreetMap project and is under ODbL license which requires identical sharing and the mandatory attribution mention must be “© OpenStreetMap contributors under ODbL license” in accordance with [http://osm.org/copyright](http://osm.org/copyright) This is a semi-automatic export with lighter and topologically verified geometries (no overlap). ###Descriptive of the contents of the “rounding” files **Origin** The data comes from the OpenStreetMap cartographic database. These were established from the cadastre made available by DGFiP on cadastre.gouv.fr. In addition on Mayotte where the cadastre is not available on cadastre.gouv.fr, it is the limits of the GEOFLA of IGN that have been used as well as the plot of the coasts from the aerial images of Bing. More info: http://openstreetmap.fr/36680-communes **Format** These files are offered in shapefile format, in WGS84 projection with several levels of detail: — simplification at 5 m — simplification at 50 m — simplification at 100 m The topology is retained during the simplification process (see: http://openstreetmap.fr/blogs/cquest/limites-administratives-simplifiees) **Content** These files contain all the French boroughs, including the DOMs, but without Mayotte. For each district, the following attributes are added: — insee_ar: borough INSEE Code — name: name of the scenting — Wikipedia: wikipedia entry (language code followed by article name) — nb_comm: number of municipalities in the borough — surf_km2: area of the borough in km² on the WGS84 spheroid If you have any questions about these exports, you can contact exports@openstreetmap.fr See also: — [contours of the French municipalities](https://www.data.gouv.fr/fr/dataset/decoupage-administratif-communal-francais-issu-d-openstreetmap) — [contours of EPCI 2014](https://www.data.gouv.fr/fr/dataset/contours-des-epci-2014) and [Contours des EPCI 2013](https://www.data.gouv.fr/fr/dataset/contours-des-epci-2013) — [contours of the French departments](https://www.data.gouv.fr/fr/dataset/contours-des-departements-francais-issus-d-openstreetmap) and [SVG maps of the departments](https://www.data.gouv.fr/fr/dataset/cartes-des-regions-et-departements-issus-d-openstreetmap) — [contours of French regions](https://www.data.gouv.fr/fr/dataset/contours-des-regions-francaises-sur-openstreetmap)
本数据集为基于OpenStreetMap(开放街道地图)制作的法国区(arrondissements)级行政区划导出数据,其数据源绝大多数源自地籍资料。 本数据由OpenStreetMap项目贡献者通过众包方式生成,采用ODbL许可协议发布,该协议要求相同方式共享,且必须按照[http://osm.org/copyright](http://osm.org/copyright)的要求标注"© OpenStreetMap contributors under ODbL license"(© OpenStreetMap贡献者,遵循ODbL许可)。 本数据集为半自动化导出产物,几何图形经过轻量化处理且已完成拓扑校验(无重叠)。 ###「轮廓」文件内容说明 **数据来源** 本数据源自OpenStreetMap(开放街道地图)制图数据库,其基础为法国公共财政总局(DGFiP)在cadastre.gouv.fr平台发布的地籍资料。 针对马约特岛,因cadastre.gouv.fr平台未提供该地地籍资料,本次导出采用了法国国家地理院(IGN)的GEOFLA行政区划边界数据,以及必应(Bing)航空影像获取的海岸轮廓数据。 更多信息请参阅:http://openstreetmap.fr/36680-communes **文件格式** 本次导出文件采用Shapefile格式,投影为WGS84坐标系,并提供多细节层次的简化版本: - 5米精度简化 - 50米精度简化 - 100米精度简化 简化过程中保留了原始拓扑关系(详见:http://openstreetmap.fr/blogs/cquest/limites-administratives-simplifiees) **数据内容** 本数据集包含法国所有区(arrondissements)级行政区划,涵盖法国海外省(DOMs),但不包含马约特岛。 每个行政区均附带以下属性字段: - insee_ar:法国国家统计与经济研究所(INSEE)编制的行政区代码 - name:行政区名称 - Wikipedia:维基百科条目(格式为语言代码+条目名称) - nb_comm:该行政区下辖的市镇数量 - surf_km2:基于WGS84椭球体计算的行政区面积,单位为平方千米 若您对本次导出数据有任何疑问,请发送邮件至exports@openstreetmap.fr。 相关参考资源: - [法国市镇行政区划轮廓](https://www.data.gouv.fr/fr/dataset/decoupage-administratif-communal-francais-issu-d-openstreetmap) - [2014年法国跨市镇公共合作组织(EPCI)轮廓](https://www.data.gouv.fr/fr/dataset/contours-des-epci-2014) 及 [2013年法国跨市镇公共合作组织(EPCI)轮廓](https://www.data.gouv.fr/fr/dataset/contours-des-epci-2013) - [法国省级行政区划轮廓](https://www.data.gouv.fr/fr/dataset/contours-des-departements-francais-issus-d-openstreetmap) 与 [法国省级行政区划SVG地图](https://www.data.gouv.fr/fr/dataset/cartes-des-regions-et-departements-issus-d-openstreetmap) - [法国一级行政区(大区)轮廓](https://www.data.gouv.fr/fr/dataset/contours-des-regions-francaises-sur-openstreetmap)
