过去常被钉在教室墙上而且常出现在地图册中的那幅地图以墨卡托投影著称，最早是由弗兰德地理学家杰拉杜斯·麦卡托提出来的，可追溯至1569年。

The map you're used to seeing pinned on classroom walls and in Atlases is known as a Mercator projection, and was first presented by the Flemish geographer Gerardus Mercator back in 1569.

测量是通过安装在教室墙上的隐蔽传感器装置实现的，并通过因特网把数据传送到远端的数据收集点。

Measurements were made using unobtrusive sensor packages mounted on classroom walls that transmitted data to a remote site using the Internet.
