    Abstract: Location-based services (LBS) gain a lot of attraction recently. However, to collect necessary and accurate information to support LBS is always manpower-consuming, and may be also difficult for machine computation. "Human Computation" can therefore be adopted to attack the problems. These problems which are usually difficult for machines to solve can be easily completed by human. We can embed our purpose into a designated game. In this way, players will automatically achieve our purpose while playing the games. In this paper, we based on the concept of `Games with a Purpose` (GWAP) to develop a mobile geospatial tagging system. Players share their nearby scenic spot information which will then be verified by other players who come to the same place later. Thus the information collected by the system can be also reliable. However, verification process can alter the performance of the system. We propose three different strategies on the task assignment for comparisons. Through simulation experiments, our system can indeed achieve good performance. Finally we implement the system on the smart phone (Android Phone), and do the field test to observe the results. © 2011 IEEE.
