At the Humanitarian OpenStreetMap team, also known as HOT, we did something different.

在 Humanitarian OpenStreetMap 团队，也称为 HOT，我们做了一些不同的事情。

For this, they turned to OpenStreetMap, an open-source rival to Google Maps in which volunteers had already tagged large numbers of solar plants.

为此，他们求助于OpenStreetMap——谷歌地图的开源竞争对手，志愿者已经在这个平台上标记了大量的太阳能发电厂。

Since 2010, HOT has engaged over 200,000 volunteers who have mapped an area home to more than 150 million people in OpenStreetMap.

自 2010 年以来，HOT 吸引了超过 200, 000 名志愿者， 他们在 OpenStreetMap 中为超过 1. 5 亿人绘制了一个区域的地图。

We map with a tool called OpenStreetMap, which was founded in 2006 and is a free, open-source tool which anyone can use to map the world.

我们使用名为 OpenStreetMap 的工具绘制地图，该工具创建于 2006 年， 是一款免费的开源工具， 任何人都可以使用它绘制世界地图。
