Interest point landmark path guiding method of spontaneous geographic information

Abstract

The invention discloses an interest point landmark path guiding method of spontaneous geographic information and relates to the mapping geographic information technology field. The path guiding methodcomprises the following steps of step1, based on Weibo social platform, acquiring VGI-POI check-in data; step2, preprocessing the acquired VGI-POI check-in data; step3, calculating validity calculation on the VGI-POI check-in data; step4, using a VGI-POI landmark path to guide selection of an optimal path; and step5, based on the optimal path, carrying out VGI-POI landmark path guiding. In the invention, path guiding can be provided for people trips, path-guided description information according with spatial cognition habits of people is generated, and a basis and reference are provided for people to scientifically select a travel route; limitations of a traditional navigation method, POI and a traditional POI landmark path guidance method are overcome to some extent so that path findingtime is reduced, psychological burden is decreased and navigation efficiency is increased; and characteristics that consumed cost is low, path guiding accords with the spatial cognition habits of people and actual usage is convenient are achieved.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping geographic information, and relates to a point-of-interest landmark route guidance method of spontaneous geographic information. Background technique [0002] Volunteered Geographic Information (VGI), as a new type of public geographic information data source, aims at individuals voluntarily providing geographic data. [0003] Point of Interest (POI) is the core content of a digital map, and refers to all entities that can be abstracted into points, especially some urban infrastructure constructions related to people's lives, which can be a building, a shop, a bus station etc., and can play a role in services such as auxiliary positioning, location query search, route query search, and navigation. [0004] Landmarks in the narrow sense refer to iconic geographical objects existing in geographic space, and landmarks in the narrow sense are included in POIs. POI landmarks mainly refe...

Problems solved by technology

[0013] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a point-of-interest landmark path guidance method based on spontaneous geographical information, that is, the VGI-POI landmark path guidance method, which solves the problem that the traditional navigation method does not conform to people's spatial cognition habits, POI and POI The technical problems of the traditional POI landmark path guidance method are costly and costly, and realize the technical effects of reasonable path guidance, convenient practical use, improved navigation efficiency, and reduced psychological burden
