This a little bit in shock that Google maps-Google, Google Earth, Google Earth-IT information This a little bit in shock at Google maps

Recently Google released the Google Earth picture of first show within ten years of deforestation in the world map. This is Google and the University of Maryland, United States National Oceanic and Atmospheric Administration and the United States Geological Survey Institute of cooperation results. Google hopes will map to prevent unnecessary deforestation.

This project uses the United States terrestrial satellite Landsat maps system ten years filming, showing the worldwide land-use changes, to inform the public, non-governmental organizations as well as Governments are able to learn about land use and deforestation in the last decade. Hoping to make their own contribution to reduce forest loss.

The project officers, Senior Professor of geography, University of Maryland Matthew Hansen described: we want people to be able to effectively use this map to find hidden in one of the new information, even using it to we are not in a project that is expected to go to. This unique tool to make the public more clearly recognized that deforestation in the world today, and easily moved people to do something for protection of forests.

This tool is based on the 654,178 satellite picture received, precisely because of the amount of enormous, so you need an extremely powerful CPU processing power, you need one computer running the 15 years before processing can be completed. From another perspective, is to benefit from the rapid development of computer technology, may only occur if such a huge amount, such high resolution maps.

This map, in addition to high resolution, maximum you can zoom in to the actual distance of 30 meters. Use this map can clearly see forest degradation due to logging, such as natural disasters, while red represents loss of forest area in the picture.

这张有点震撼的谷歌地图

日前谷歌发布了其利用Google Earth描绘的全球第一张展现十年内森林砍伐情况的地图。这是谷歌与马里兰大学、美国国家航空航天局以及美国地质调查局的研究院共同合作的的结果。谷歌希望借此地图来阻止不必要的森林砍伐。

这个项目利用了美国陆地探测卫星系统十年内拍摄的陆地卫星地图，展示了全球土地使用的变化情况，使公众、非政府组织以及各国政府都能了解近十年来土地使用以及森林砍伐的情况。希望能为减少森林流失而做出自己的贡献。

该项目的领导人员，马里兰大学资深地理科学教授Matthew Hansen这样描述：我们希望人们能够有效利用这个地图，从而发现隐藏在其中的新信息，甚至于将其利用到我们都无法预计的项目中去。这个特殊的工具能够使公众更加清晰的认识到当今世界上的森林砍伐情况，并且很容易触动人们为保护森林做些事情。

这个工具其实是在654178张卫星图片的基础上得到的，正是由于其信息量巨大，所以需要极其强大的CPU处理能力，需要一台计算机运行15年才可以完成信息处理。从另一个角度来说，正是得益于计算机技术的飞速发展，才有可能出现信息量如此庞大、分辨率如此之高的地图。

这张地图除了分辨率高之外，最大可以放大到实际距离30米。利用这张地图可以清晰的查看因伐木、自然灾害等造成的森林退化现象，而图片中红色部分则代表森林面积流失。
