Problems solved by technology

[0004] The purpose of the present invention is to provide a visualization method suitable for personal geographic marking data, so as to solve the problems existing in existing visualization methods that users cannot use the spatial location as an entry to find the information they are interested in and that too many geographical elements on the map easily interfere with users. quick perception problem

Embodiment Construction

[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] A visualization method suitable for personal geographic mark data proposed by the present invention is a visualization method (referred to as a marker topology map) suitable for personal geographic mark data (mainly text and photo data), the purpose of which is to remove the map background and abandon the original The accuracy of the data, only the relative positional relationship of the data is retained, the points in the dense area are stretched, and the points in the sparse area are compressed, and finally a marked topological map with a distance of 1 between any two points on the X and Y axes is obtained. The specific implementation process of the method is as follows.

[0028] The proposal of the tag topological map is mainly based on the basic theory of cognitive map. Under the guidance of the basic theory of cognitive map, the ...

Abstract

The invention relates to a visualization method suitable for personal geographical indication data, and belongs to the technical field of data visualization processing. When the personal geographical indication data is processed, a background map is removed, points in a dense region are stretched and points in a sparse region are compressed so as to obtain an indication topological graph of which all geographical positions are displayed on one graph on a premise that orientation orthogonality is kept constant. Through the above process, the personal geographical indication data can be simply displayed, deformed geographical points still keep original relative position relationship, and finally, all position points can be displayed in the same graph. When the invention is compared with a text list and a common map, the search efficiency of the invention is superior to the search efficiency of the common map and is superior to the search efficiency of the text list when the amount of the personal geographical indication data is large.

Description

technical field [0001] The invention relates to a visualization method suitable for personal geographical mark data, belonging to the technical field of data visualization processing. Background technique [0002] Personal geotagging data is published by individuals through devices such as laptops, tablets, or mobile phones, including geographic location, personal-related texts, photos, and videos (such as Tencent WeChat Moments or Sina Weibo, etc.). At present, mature commercial websites mainly have two visualization methods for these data. One is to organize text and photo information by publication time, and the other is to overlay geotagged data on a common map for display. [0003] The first method only displays the spatial location in the list in the form of text or illustrations, and users cannot use the spatial location as an entry to find the information they are interested in. The second method is a traditional thematic data visualization method, but due to the c...
