This data from Planet labs Inc. SkySat satellites was collected for the experimental "Skybox for Good Beta" program in 2015, as well as for various crisis response events and a few other projects. The data is available in both a 5-band Multispectral/Pan collection, and a Pansharpened RGB collection.
Each image's asset ID contains the acquisition date and time, for example, image s01_20150304T080608Z was acquired on March 4, 2015 at 08:06 Zulu (UTC). For more information, please see the [Planet Imagery Product Specifications] (https://www.planet.com/products/satellite-imagery/files/Planet_Combined_Imagery_Product_Specs_December2017.pdf) and visit the [Planet Imagery and Archive] (Satellite Imagery and Archive | Planet) site.
This Multispectral/Pan collection contains images with five 16-bit bands shifted up from the original 12-bit data. The B, G, R, and Near-IR bands have a resolution of approximately 2m per pixel, while the Pan band is approximately 0.8m resolution (closer to 1m for off-nadir images).
这些数据来自Planet labs Inc. SkySat卫星在2015年为实验性的 "Skybox for Good Beta "项目,以及各种危机应对事件和其他一些项目收集的数据。这些数据有5个波段的多光谱/全景收集,以及一个全景锐化的RGB收集。
每张图片的资产ID包含了采集日期和时间,例如,图片s01_20150304T080608Z是在2015年3月4日08:06 Zulu(UTC)采集的。欲了解更多信息,请参见[行星图像产品规格](https://www.planet.com/products/satellite-imagery/files/Planet_Combined_Imagery_Product_Specs_December2017.pdf),并访问[行星图像和档案](https://www.planet.com/products/planet-imagery/)网站。
这套多光谱/潘氏图像集包含了从原始12位数据上移的五个16位波段的图像。B、G、R和近红外波段的分辨率约为每像素2米,而Pan波段的分辨率约为0.8米(离地图像则接近1米)。
