Fine mapping street Hamburg

The data set contains information on the use and surface material of the individual objects in the street space of the district and main roads.
As a rule, all objects in the area of civil engineering assets of the FHH are included in the data set. Areas in the area of responsibility of Autobahn GmbH and the port are not included. Areas that clearly belong to the urban road area, but are currently not legally attributed to civil engineering assets for various reasons, are also included and are marked with the attribute "foreign property".
Included attributes: District number, district, district number, district, street name, street type, category, usage number, usage, content number, content (surface material), level number, level (location regularly at street level or above or below), third-party property, source, remark, area (in m^2), object ID and status of acquisition.

The initial mapping of roads was carried out on the basis of an aerial image digitisation in the individual districts between 2013 and 2021.
The maintenance of the data has been carried out continuously since 2022 on the basis of planning documents, aerial and traffic diagrams by the state operation Geoinformation and Surveying on behalf of the Authority for Transport and Mobility Transition. The actuality of the respective object can be found in the attributes.

本数据集涵盖区域及主干道街道空间内各类单体物件的使用属性与表面材质信息。
通常而言，FHH土木工程资产覆盖范围内的所有物件均纳入本数据集。Autobahn GmbH及港区责任范围内的区域未被纳入。而虽明确归属城市道路范畴，但因各类原因目前尚未在法律上归类为土木工程资产的区域，同样会被纳入本数据集，并以"foreign property（外来产权）"作为属性标记。
包含的属性字段如下：区域编号、区域名称、区域编号、区域名称、街道名称、街道类型、类别、使用编号、使用属性、内容编号、内容（表面材质）、层级编号、层级（说明为常规位于路面层、路面层上方或下方）、第三方产权、来源、备注、面积（单位：平方米）、物件ID以及采集状态。
道路的初始测绘工作于2013年至2021年间，基于各区域的航空影像数字化工作完成。
自2022年起，地理信息与测绘部门（Geoinformation and Surveying）受交通与出行转型管理局委托，基于规划文件、航空影像及交通图表持续开展数据维护工作。各物件的最新状态可通过对应属性字段查询获取。
