Google Earth Engine——真彩色数据集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


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 RGB collection contains images with three pansharpened, 8-bit bands. The resolution is approximately 0.8m per pixel (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。

每张图像的资产ID包含了采集日期和时间,例如,图像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。

这个RGB系列包含有三个泛锐化的8位带的图像。分辨率约为每像素0.8米(离地图像接近1米)。
