It is a technology that uses lasers to map the Earth’s surface.
这是一种利用激光测绘地球表面的技术。
The data used for the study came from around 122 square kilometers of high-quality Lidar data collected in 2013.

The project aimed to reduce emissions from tree cutting, or deforestation, and land damage.
该项目旨在减少树木砍伐（即森林砍伐）和土地破坏所造成的排放。
Researchers wrote in the study, published by Cambridge University Press, that "The discovery of Valeriana highlights the fact that there are still major gaps in our knowledge of the existence or absence of large sites within as-yet unmapped areas of the Maya Lowlands.
研究人员在剑桥大学出版社发表的研究中写道：“瓦莱里亚纳的发现凸显了一个事实，即我们对玛雅低地尚未测绘区域是否存在大型遗址的认识仍存在重大空白。”
