IVS Inventory of historical transport routes Canton of Aargau regionally and locally

This dataset is derived from the inventory of historical traffic routes in Switzerland (ITS). It contains only the routes in the Canton of Aargau with the line elements of local and regional importance. The extension "historical course eliminated" has been added to the classification of the historical course. It refers to cases in which substance that was still present at the time of initial detection has been eliminated in the meantime. This extension is not systematically processed over the entire canton, but is recorded when a change is discovered. The date of the mutation (discovery) is entered in the ivs_mutdat attribute. In addition, a GlobalID has been assigned so that each object can be uniquely identified. The documentation of the first admission is divided into 3 types: Route description, line layout and section. These descriptions were also linked in the corresponding attribute field. All other attributes were taken from "Data model for the inventory of historical traffic routes in Switzerland" in 2007, the URL link: https://www.ivs.admin.ch/images/services/downloads/geodaten/PDF/BE095_Rev002_070406_LMGIS_IVS-Datenmodell_Revision1.pdf本数据集源自瑞士历史交通线路名录（ITS），仅收录阿尔高州（Canton of Aargau）内具备地方及区域重要性的线路段。历史线路的分类中新增了“历史轨迹已移除”扩展项，该扩展项用于指代初始检测时仍存在的相关实体在此后被移除的情形。该扩展项并未在全州范围内进行系统性处理，仅在发现线路变更时予以记录。变更（发现）日期记录于ivs_mutdat属性字段中。此外，已为每个对象分配GlobalID以实现唯一标识。首次录入的文档分为三类：线路描述、线路布局与路段，上述三类描述均已关联至对应的属性字段内。其余所有属性均取自2007年发布的《瑞士历史交通线路名录数据模型》，其官方链接为：https://www.ivs.admin.ch/images/services/downloads/geodaten/PDF/BE095_Rev002_070406_LMGIS_IVS-Datenmodell_Revision1.pdf
