谷歌地球引擎:监测气候变化的强力工具 / Audrey Watters

At the United Nations COP 16 conference today, Google unveiled its latest Labs project, Google Earth Engine, a new tool to give scientists, communities, and environmental activists with better access and understanding of climate change. Google Earth Engine is an online environment monitoring platform that provides a dynamic, digital model of the planet that is updated daily.

在今天的联合国缔约方16次会议上,谷歌展示了最新的实验室项目:谷歌地球引擎。这是一个新工具,为科学家,社区工作者和环境活动者更好地接触和了解气候模型提供帮助。谷歌地球引擎是一个在线的环境监测平台,提供一个地球的动态数字模型,并且每日更新。

This new platform brings online for the first time an “unprecedented amount of satellite imagery and data” – the complete archive of more than 25 years of historical satellite imagery. This archive is on the terabyte scale, and few organizations have the storage or computing power to handle it. Therefore much of this information has up til now gone unused.

这个新的平台首次将“前所未有的大量卫星图像和数据”带到网上,总共有超过25年的完整的历史卫星图像档案。这些档案的规模达到了T级,只有少数组织有处理它的存储和计算能力。因此许多其中的数据直至今日仍未得到使用。

Google hopes that the new Earth Engine will allow people to better monitor and visualize environmental changes. This project is important, says Google, as “scientific analysis can transform these images from a mere set of pixels into useful information–such as the locations and extent of global forests, detecting how our forests are changing over time, directing resources for disaster response or water resource mapping.”

谷歌希望这个新的地球引擎能让人们更好的监测和形象地观察气候变化。谷歌说,这个项目很重要,因为“科学的分析能够将这些图像从单纯的一堆像素转换成有用的信息,比如全球的森林范围和位置——以观察我们的森林如何随着时间变化,为灾难响应调配资源——或者水资源的分布。”。

Google says it is donating 10 million CPU-hours a year over the next two years on the Google Earth Engine platform, to strengthen the capacity of developing world nations to track the state of their forests. According to Google, “for the least developed nations, Google Earth Engine will provide critical access to terabytes of data, a growing set of analytical tools and our high-performance processing capabilities. We believe Google Earth Engine will bring transparency and more certainty to global efforts to stop deforestation.”

谷歌说在接下来的两年中将会贡献1000万CPU小时的计算能力给谷歌地球引擎,用于加强发展中国家跟踪其森林状态的能力。根据谷歌的说法,“对于数量最少的发达国家,谷歌地球引擎将提供关键性的访问,包括上T的数据,一套增长的分析工具和高性能的处理能力。我们相信,谷歌地球引擎将为停止砍伐森林所作的全球性努力将带来透明性和更多的确定性。”

The Google Earth Engine API is currently available to a small group of partners, but hopes to expand the program’s reach as well as its functionality.

谷歌地球引擎API目前对一小部分合作伙伴开放,但有希望在将来扩大程序的开放程度,同时增加更多功能。
