H3: Tiling the Earth with Hexagons
推荐理由
They go into a lot of the details later on the same video.
说明
这是2018年由Uber Engineering发布的一部演讲,主题归在Databases & storage。它讲的是geospatial indexing这一支里的具体问题,而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成:Uber Engineering's Joseph Gilley explains why Uber uses hexagons for geospatial indexing and introduces H3, its open source hierarchical grid system. He covers use cases and how distortion is handled.这些读者给出的理由,核心是:HN points to it as the detailed explanation of why hexagons suit map grids, in threads about H3.讲法不绑某一条新闻,过几年仍然可以当材料看。从2018年到2025年,有1位不同的读者在1个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合一次性看完。讲者把一个判断讲透,演示是在给这个判断配例子。如果已经会了基本定义,就把注意力放在它怎么把geospatial indexing变成能跟着复述的例子。
