Power Plant Satellite Imagery Dataset
收藏资源简介：
This dataset contains satellite imagery of 4,454 power plants within the United States. The imagery is provided at two resolutions: 1m (4-band NAIP iamgery with near-infrared) and 30m (Landsat 8, pansharpened to 15m). The NAIP imagery is available for the U.S. and Landsat 8 is available globally. This dataset may be of value for computer vision work, machine learning, as well as energy and environmental analyses.<br>Additionally, annotations of the specific locations of the spatial extent of the power plants in each image is provided. These annotations were collected via the crowdsourcing platform, Amazon Mechanical Turk, using multiple annotators for each image to ensure quality. Links to the sources of the imagery data, the annotation tool, and the team that created the dataset are included in the "References" section.<br>To read more on these data, please refer to the "Power Plant Satellite Imagery Dataset Overview.pdf" file. To download a sample of the data without downloading the entire dataset, download "sample.zip" which includes two sample powerplants and the NAIP, Landsat 8, and binary annotations for each.<br><br>Note: the NAIP imagery may appear "washed out" when viewed in standard image viewing software because it includes a near-infrared band in addition to the standard RGB data.<br><br><br>
本数据集包含美国境内4454座发电厂的卫星影像。该影像提供两种分辨率规格：1米分辨率（含近红外波段的4波段美国国家农业影像计划（NAIP）影像），以及30米分辨率（经15米全色锐化处理的陆地卫星8号（Landsat 8）影像）。其中NAIP影像仅覆盖美国区域，Landsat 8影像则覆盖全球范围。本数据集可应用于计算机视觉、机器学习以及能源与环境分析等相关研究与工程场景。<br>此外，数据集还提供了每张影像中发电厂空间范围的精准位置标注。此类标注通过众包平台亚马逊机械 Turk（Amazon Mechanical Turk）采集，每张影像均由多名标注人员参与标注以保障标注质量。影像数据源、标注工具以及本数据集开发团队的相关链接已收录于"References"章节。<br>如需了解更多数据集详情，请参阅"Power Plant Satellite Imagery Dataset Overview.pdf"文件。若无需下载完整数据集即可获取样本数据，可下载"sample.zip"，该压缩包包含两座示例发电厂的相关数据，以及对应NAIP、Landsat 8影像与二值化标注文件。<br><br>注意：由于除标准RGB波段外额外包含近红外波段，NAIP影像在普通图像查看软件中可能呈现"泛白"效果。
