Highly accurate maps for barrier-free indoor navigation

This dataset contains vectorized indoor map data for barrier-free indoor navigation. It is highly accurate georeferenced indoor data from an ever-increasing number of buildings. Specifically, in the vast majority of cases, at least the following information is included:

- Walls
- Doors
- Stairs, elevators, escalators
- rooms with name and room type, and possibly keywords as well as information on accessibility

After approval of the account, the data can be queried directly via a graphql interface (see usage instructions). In addition, directly usable SDKs for Android and iOS applications are available after licensing. This makes the data particularly easy to use in mobile applications and can be used directly in conjunction with the Fraunhofer system everGuide, e.g. for barrier-free turn-by-turn navigation.

本数据集收录用于无障碍室内导航的矢量化室内地图数据，包含来自日益增多的楼宇、经高精度地理配准的室内数据。绝大多数场景下，该数据集至少涵盖以下信息：
- 墙体
- 门
- 楼梯、电梯、自动扶梯
- 带有名称与房间类型，可能还包含关键词及无障碍相关信息的房间

账户审核通过后，可直接通过图查询语言（GraphQL）接口查询该数据（详见使用说明）。此外，经授权许可后可获取适用于Android与iOS应用的即用型SDK，可便捷地将该数据集成至移动应用中，还可直接与弗劳恩霍夫（Fraunhofer）的everGuide系统配合使用，例如实现无障碍逐向导航。
