寻找不在地图上的隐形人
There are often no maps of rural areas of Rwanda
卢旺达的农村地区往往没有地图
“There are about two billion people in the world who don’t appear on a proper map,” says Ivan Gayton from the charity Humanitarian OpenStreetMap.
“世界上大约有20亿人没有出现在正确的地图上，”慈善机构“人道主义开放式街道地图”的伊万·盖顿说。
“It’s shameful that we – as cartographers of the world – don’t take enough interest to even know where they are. People are living and dying without appearing on any database.”
“我们作为世界地图绘制者，没有足够的兴趣去知道他们在哪里，这是可耻的。人们在没有出现在任何数据库中的情况下生存和死亡。”
Known as the “Wikipedia for maps”, anyone can download OpenStreetMap and edit it too.
OpenStreetMap被称为“地图维基百科”，任何人都可以下载OpenStreetMap并对其进行编辑。
“It’s an amazing situation where anyone could wreck it, anyone can add to it, but what we’ve ended up with is a map that is the most up-to-date in some places.”
“这是一个惊人的情况，任何人都可以破坏它，任何人都可以添加它，但我们最终得到的是一张在某些地方最新的地图。”
According to Mr. Gayton, it is the most complete and accurate map for many parts of the world, especially in rural Africa, where underinvestment means, outside of cities, there are often blank pages where millions live.
盖顿认为，这是世界许多地区最完整、最准确的地图，尤其是在非洲农村地区，那里的投资不足意味着，在城市之外，数百万人居住的地方经常有空白页。
Ivan Gayton believes better data will solve critical healthcare issues
伊万·盖顿认为，更好的数据将解决关键的医疗保健问题
As we sit in Rwanda, Mr. Gayton gestures into the distance: “It’s not very far from here, over in the Democratic Republic of Congo just across the border, where the information all but stops. It’s not like people don’t live there, they just aren’t recorded.”
当我们坐在卢旺达时，盖顿先生向远处示意：“离这里不远，就在边境对面的刚果民主共和国，那里的信息几乎停止了。这并不是说人们不住在那里，他们只是没有被记录下来。”
So why does it matter?
那为什么重要呢？
Mr. Gayton says it can be a matter of life and death. “If you take an outbreak of disease like Ebola or the new coronavirus, contact tracing is how you stop epidemics. It’s not the treatment, it’s the public health and map data that makes it possible.”
盖顿表示，这可能是一个生死攸关的问题。”如果你爆发了像埃博拉病毒或新型冠状病毒这样的疾病，接触追踪就是阻止传染病的方法。这不是治疗，只有公共健康和地图数据才能使它成为可能。”
