Overture Maps - Buildings

**Overview**
The Overture buildings theme describes human-made structures with roofs or interior spaces that are permanently or semi-permanently in one place (source: OSM building definition).

1. Buildings: Buildings are human-made structures with roofs or interior spaces that are permanently or semi-permanently in one place. The most basic form of a building feature in the Overture Schema. The geometry is expected to be the most outer footprint (or roofprint if traced from satellite/aerial imagery) of a building. A building is a man-made structure with a roof that exists permanently in one place.
2. Building parts: A single building part. Parts describe their shape and color and other properties. Each building part must contain the building with which it is associated.

Founded in 2022 under the Joint Development Foundation, Overture Maps Foundation (Overture Maps) is dedicated to the development of reliable, easy-to-use, and interoperable open map data that will power current and next-generation map products. We build this data through a collaborative process that combines technology, data, and support from a wide range of companies. Map data are assembled from multiple sources including members, civic organizations, and open data sources.

However, if the data associated though GERS with an ODbL licensed theme constitutes a derivative dataset, it must be licensed under ODbL.

**Use cases**
- Risk Analysis: Analyze what buildings have a higher risk to suffer damages from extreme weather events by leveraging Overture's building footprints.
- Foot Traffic Analytics: Cross-reference your human mobility data with Overture's building footprints in order to analyze the estimated foot traffic in each building.

**Additional Insights**
This data is processed, onboarded and maintained by CARTO in collaboration with the Overture Maps Foundation.

**概述**
Overture建筑主题（Overture buildings theme）描述的是永久或半永久固定于一处、带有屋顶或内部空间的人造构筑物（来源：OpenStreetMap（OSM）建筑定义）。

1. 建筑（Buildings）：指永久或半永久固定于一处、带有屋顶或内部空间的人造构筑物，是Overture数据架构（Overture Schema）中最基础的要素类型。其几何形状应为建筑的最外侧轮廓（若通过卫星/航空影像勾绘则为屋顶轮廓（roofprint））。建筑即为带有屋顶、永久固定于一处的人造构筑物。
2. 建筑部件（Building parts）：指单个建筑部件。部件描述自身的形状、颜色及其他属性，每个建筑部件均需关联至其所从属的建筑。

Overture地图基金会（Overture Maps Foundation）于2022年在联合开发基金会（Joint Development Foundation）框架下成立，致力于打造可靠、易用且具备互操作性的开放地图数据，为当前及下一代地图产品提供支撑。我们通过融合技术、数据与众多企业支持的协作流程构建此类数据。地图数据整合自多个来源，包括基金会成员、民间组织及开放数据源。

Overture的数据主题与架构采用CC-BY 4.0协议进行授权。GERS ID采用CDLA Permissive v 2.0协议进行授权。通过GERS与各数据主题关联的数据可采用不同许可协议。但若通过GERS关联至ODbL许可数据主题的数据构成衍生数据集，则该衍生数据集必须采用ODbL进行授权。有关衍生数据库的定义，请参见OpenStreetMap社区指南。

**应用场景**
- 风险分析（Risk Analysis）：利用Overture的建筑轮廓数据，分析哪些建筑在极端天气事件中面临更高的损毁风险。
- 人流分析（Foot Traffic Analytics）：将您的人类移动数据与Overture的建筑轮廓数据进行交叉比对，以估算各建筑的人流情况。

**额外洞察**
本数据集由CARTO与Overture地图基金会合作进行处理、接入与维护。
