Bavaria Building Dataset (BBD)
收藏资源简介：
The Bavarian Building Dataset (BBD) is an analysis-ready dataset providing an openly available 40cm image dataset over Bavaria (CC-BY4.0, Digitales Ortophoto 40cm - DOP40, https://geodatenonline.bayern.de/) combined with building footprint information as GIS data (Shapefiles) and co-registered imagery. This data has been taken from official building footprints as published openly (CC-BY 4.0, Hausumringe, https://geodaten.bayern.de/). In addition, our dataset contains building footprint geometry (Shapefile) and co-registered masks based on a historic OpenStreetMap extract dating to 2021. The data has been preprocessed and co-registered and is provided as a set of tiles ready for deep learning and other data analysis techniques. The tileset is available as 18.205 tiles of 2500x2500 pixels (each 40cm x 40cm) as well as as a collection of about 5.5 million tiles (210 GB, PNG) of 250x250 pixels for immediate use with computer vision models. The dataset is supposed to support image segmentation research, building footprint extraction research and further interdisciplinary research both on methods and on Bavaria. The dataset is supposed to be updated with each major re-publication of the upstream data sources to foster change detection research in the future.
巴伐利亚建筑数据集（Bavarian Building Dataset, BBD）是一款分析就绪的开源数据集，涵盖巴伐利亚州全域40厘米分辨率的公开影像数据集（采用CC-BY4.0许可协议，源自Digitales Ortophoto 40cm - DOP40，来源链接：https://geodatenonline.bayern.de/），同时配套地理信息系统（Geographic Information System, GIS）格式的建筑轮廓（building footprint）数据（Shapefile格式）与配准后影像。该数据集的官方建筑轮廓数据源自公开发布的官方资料（采用CC-BY 4.0许可协议，原数据为Hausumringe，来源链接：https://geodaten.bayern.de/）。此外，本数据集还包含基于2021年开放街道地图（OpenStreetMap）提取的建筑轮廓几何信息（Shapefile格式），以及与之配准的掩膜数据。本数据集已完成预处理与配准，以分块形式提供，可直接用于深度学习及其他数据分析任务。该数据集包含两类分块：一类为18205张2500×2500像素的分块（单像素对应40cm×40cm地面范围）；另一类为约550万张250×250像素的PNG格式分块，总容量210GB，可直接适配计算机视觉模型使用。本数据集旨在支持图像分割、建筑轮廓提取相关研究，以及面向巴伐利亚州的跨学科方法与应用研究。未来将随着上游数据源的重大更新同步更新本数据集，以助力未来的变化检测研究。
