Planet SkySat Public Ortho Imagery, RGB
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
说明
这些数据来自 Planet Labs Inc. 的 SkySat 卫星，于 2015 年收集，用于实验性“Skybox for Good Beta”计划，以及各种灾难应对活动和其他一些项目。该数据以 5 波段多光谱/全色影像集和全色锐化 RGB 影像集的形式提供。
每个图片的素材资源 ID 都包含采集日期和时间，例如，图片 s01_20150304T080608Z 是在 2015 年 3 月 4 日 08:06（祖鲁时间 [UTC]）采集的。如需了解详情，请参阅 Planet 影像产品规格，并访问 Planet 影像和归档网站。
此 RGB 集合包含具有三个经过全色锐化的 8 位波段的图片。分辨率约为每像素 0.8 米（对于非天底图像，分辨率更接近于每像素 1 米）。
