| 摘 要： | 目前，政区地图具备多级钻取、图表联动展示功能，但是需要提前统计数据，不能在线实时统计，缺少数据立方体数据切片、灵活展现能力。针对此问题，本文提出了政区地图和数据立方体结合的联机可视化方法，通过多级政区地图与数据立方体深度融合，实现政区数据在线实时统计并联动显示各级政区多维数据（如对省级、市级、县级、乡镇级），试验证明该方法具有较好的在线分析和交互效果。

| Abstract: | At present, the political district map has multi-level drilling and chart linkage display functions, but it needs statistical data in advance, can not be online real-time statistics, lacks data cube data slicing, flexible display capability, and proposes a combination of political map and data cube for this problem. Online visualization method, through the deep integration of multi-level political district maps and data cubes, real-time statistical real-time statistical parallel display of political district data shows multi-dimensional data of various political districts (for example, provincial, municipal, county, township level), test certificate This method has better online analysis and interaction effects. |
