Embodiment Construction

[0030] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described below through specific embodiments and accompanying drawings.

[0031] A typical timing statistics are shown in Table 1 below:

[0032] Table 1. Timing Statistics

[0033]

[0034]

[0035] Taking the above time-series statistical data as an example, the statistical map drawing method supporting time-series feature detection in this embodiment, its process is as follows figure 1 shown, including the following steps:

[0036] 1. According to the time series statistical data, calculate the statistical indicators that need to be analyzed and presented. Such as mean, variance, maximum value, etc.

[0037]2. According to the geographical area information of the statistical data, draw the statistical indicator data inside the edge of the geographical area. Due to the phenomenon of overlapping edges betw...

Abstract

The invention relates to a statistics map drafting method for supporting timing sequence characteristic exploration. According to the method, timing sequence statistics data is drafted into the internal portion of a geographic area according to the geographic area information of the timing sequence statistics data and timing sequence characteristics to acquire a statistics map; statistics index data is further drafted to an inner side of the geographic area edge, firstly, according to the timing sequence statistics data, statistics indexes needing analysis and representation are calculated; and secondly, according to the geographic area information of the timing sequence statistics data, the statistics index data is drafted to the inner side of the geographic area edge. The method is advantaged in that on the condition that the space is utilized to the maximum degree, the integral characteristic of the statistics data and the timing sequence characteristic are explored, and thereby integral and timing sequence characteristic visualization of the timing sequence statistics data can be realized.

Description

technical field [0001] The invention belongs to the fields of cartography and information visualization, and relates to a statistical map drawing method that supports time-series feature exploration. Compared with traditional statistical maps, the method can support the overall characteristics of statistical data under the condition of maximum utilization of space. and timing features. Background technique [0002] Statistical data is the data obtained after statistical analysis of a specific indicator. Through the visualization of statistical data, it can help analysts discover the knowledge behind the data, thereby assisting in problem discovery or decision making. Statistical map is a visualization method that uses statistical data to reflect the quantitative characteristics of cartographic objects. It can present statistical data with spatial information on the map, which has very positive significance in auxiliary analysis. [0003] However, for time-series statistical...
