Abstract

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.

Key words: government electronic map, data cube, OLAP
