But as Jerry Brotton explains in “A History of the World in Twelve Maps”, Ptolemy's scientific influence tells only part of the story.

但正如杰里·布洛顿在《12幅地图中的世界史》中解释的那样，托勒密的科学影响力只是这个故事的部分。

Even now, when mapmakers have access to tools such as satellite images, there is still no objective and universally accepted map, argues Mr Brotton.

布洛顿先生认为，即便是现在，虽然绘图者有卫星影像这样的工具可用，准确的、可被普遍接受的地图依然难觅。
