The Design And Implementation Of The Indoor Vector Map SDK On Android

With the technology development of smart mobile phones, Mapping applications are playing a more important role in people’s life, many common mobile application provides basic map services, but, as a result of these applications to render the content in the form of raster bitmap, the file’s size will be very big, that leads to user’s network data is used up very quickly. Or, users need to download a lot of static data packets. It’s not convenient to update map’s data files. We urgently need a vector format instead of a bitmap format to show a map content; Also, The existing electronic map services currently only provide outdoor map services, the indoor map field is still belongs to the fledgling stage. Therefore, the indoor vector map service for large buildings becomes more and more important. Study at indoor vector map for android meets the broad market demand and the huge market potential.First, this paper analyzes the geographic information system in the smart phones, and we compared the respective advantages and disadvantages, then we refer to the existing technology to design our own map system. The design of SDK for indoor vector map needs to optimize the display effect, therefore, this article focuses on the design of render, and, how to make the map’s UI. At the same time, this paper provides the SDK integration solutions on the android devices. And, we develop a enroll application sample for campus. The sample shows the map SDK can give LBS application a better user experience, it is convenient to combine users’personal information with geographic information. Also, the vector map format greatly improves the display performance of application. At present, the SDK (Software Development Kit), and the application which is based on it are already stability running, they are offering location query, information query, information sharing, and other kinds of map services, which facilitate the people’s life and work.
