In general, we can use traditional navigation system to get to our destinations, but we can not continue using navigation indoor because of the requirement of position accuracy and weak signal. Hence, 2D&3D indoor navigation features are provided in SuperMap iMobile which not only solve this problem but also can experience navigation more intuitively.

Besides the basic feature of navigating in the same floor, the features of indoor navigation in iMobile includes:

• Map display in 2D, 3D indoor
• Switch indoor floors
• Road planning of crossing floors and multiple passing positions
• Indoor simulation navigation, real navigation
• Navigation speech broadcast

This article will introduce how to use SuperMap iDesktop to realize the iMobile indoor navigation data production and function application from the aspects of data structure of the navigation map, the data creation and loading and use of the three-dimensional indoor navigation.
