A Software Development Kit For Display And Control Of Indoor Maps

With the popularization of computer and the development of geographic information system, maps can be interactively visualized on the computer. The electronic map is the basis of geographic information system. It provides the geographic information system with the function of display. Nowadays, with the development of social economy, the activity territory of people is bigger than before, and the geographic information used in life is also much more than before, so the demand of accessing the electronic maps anytime and anywhere is also in constant growth. However, at present, most of the existing electronic map services on the Internet are only available for outdoor maps. Indoor map service field has just started. At the same time, the functions of some existing electronic map services are not perfect. For example, they don’t provide interface for indoor maps web application development, map data cannot be updated online by the users, etc.Based on the above reasons, we studied the technology of display and control of indoor maps. We develop a SDK (stands for Software Development Kit) for the display and control of indoor maps for the desktop browser application using the JavaScript language. The SDK provides many functions, for example, the display and control of map image, the adding of map controls, the adding of map markers and polygonal lines. The SDK is open to developers who want to embed an indoor map system in their web pages. The indoor map SDK provides some practical tools to process map content, and to add content to the map through a variety of functions. Developers only need to quote our JavaScript files on their web sites, or to download the SDK, they can create a full-featured indoor map application on the site.In this dissertation, on the basis of the analysis of the geographic information system and online electronic map open API technology, we researched and developed a SDK for the display and control of indoor map. Then, with this SDK, we rewrote our old indoor map website, and increased a new function for the site, that is, allowing the users modify map online. After that, we discussed the influences on the development, maintenance, and user experience, which are brought in by the use of the SDK. Finally, we discussed the characteristics of SVG maps, and developed a DEMO version of the SDK for SVG maps.The SDK for display and control of indoor maps is now open for use. Web front-end engineers can call it which provides users with all kinds of map service. At present, this SDK has been applied in the campus map service system of Beijing University of Posts and Telecommunications.
