Indoor map and making method thereof

Abstract

The invention relates to an indoor map and a making method thereof. The making method comprises the steps of acquiring and obtaining cartographic data of a cartographic area, classifying and layering the cartographic data, further dividing each feature class into a plurality of feature layers, determining an adopted indoor map type, namely an indoor layout map, an indoor route map or an indoor escape map, determining map data of the cartographic area according to the feature layer corresponding to the selected indoor map type, expressing priority according to the feature layers in the map data, determining specific cartographic contents of the maps in different scales, and generating and outputting the indoor map according to the determined specific map contents. According to the indoor map and the making method thereof, the indoor data is classified and layered, so that the method is applicable to various indoor environments; carrying capacities of the maps in different scales are considered; expression priorities are set for indoor data layers; the corresponding map contents are displayed according to different map scales; the requirement of a user on map cognition is met; and the map can better serve for indoor and outdoor navigation.

Description

technical field [0001] The invention relates to a method for classifying indoor map data, the map data of which is beneficial to GIS data management and analysis, and relates to a method for making an indoor map and the indoor map obtained by the method to serve indoor navigation. Background technique [0002] Nowadays, indoor and outdoor navigation is a hot research field. Outdoor navigation is supported by various mature maps, while indoor navigation uses planar diagrams as its map basis. Plane schematic diagrams are usually physical graphics fixed on the interior walls of buildings, etc., facing all kinds of people entering and leaving the place and taking into account the needs of different aspects as much as possible. The production method is based on "GB / T20501.3-2006 Public Information Guidance System Design Principles and Requirements for Elements Part 3: Floor Plans and Information Boards. The plane diagram has no clear data classification and layering, and each da...

Problems solved by technology

[0007] Aiming at the problem of indoor map drawing, there is no corresponding research result in China at present, and there are some academic literatures abroad, mainly including: "The design of a handheld, location-aware guide for indoor environments" (Ciavarella et al., "Personal and ubiquitous computing"), "You-are-here maps in emergencies——the danger of getting lost" (Klippel et al., "Journal of spatial science"), "Towards designing better maps for indoor navigation: experiences from a case study" (Puikkonen etc., "In Proceedings of the8th International Conference on Mobile and Ubiquitous Multimedia"), however, the above-mentioned literature only discussed some principles of indoor map design, and did not study its specific production methods and processes
