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。
此多光谱/全色影像集包含 5 个 16 位波段的影像,这些波段是从原始 12 位数据向上偏移的。B、G、R 和近红外波段的分辨率约为每像素 2 米,而全色波段的分辨率约为 0.8 米(对于非天底图像,分辨率更接近 1 米)。
