A Location Based Service (LBS) provides useful information to the users based on the geographic location the user designates or the user is currently located. Examples of LBS include directory service, gateway service, location utility service, presentation service, route service, and so on. These services are very useful to the users, and LBS should be available indoor: subways, large shopping malls, department stores, factories, and so on. This manuscript summarizes the techniques needed in development of Indoor LBS (ILBS) including indoor positioning, indoor moving objects database system, rendering drawings, and web service.
