massive map data的意思|示意

The second piece of infrastructure is a computation framework called Map-Reduce that works closely with the GFS to allow you to efficiently process the massive amount of data that you have collected.

第二个基础设施是名为Map - Reduce的计算框架，它与GFS紧密协作，帮助处理收集到的海量数据。

To improve the efficiency of automatic maps edge matching of massive digital map data of great regions even global ones, virtual stitching algorithm based on vector ID mapping is presented.

为了改善数字地图图幅自动接边算法在处理大区域甚至全球范围的大数据量图幅接边时效率低的问题，提出了基于矢量id映射的“虚拼接”算法。
