This paper evaluates a map expression, which is the spatial smoothing of the point distribution, from the map user's standpoint. In general, if a spatial data is smoothed, we may focus on a global structure of the distribution. In this case, it is thought that the amount of the location information in the map decreases. So, the degree of smoothing affects the way and result of map use. In this paper, the probabilistic model that expressed the man's acknowledgment of spatial smoothing map is presumed. An experiment was performed that asked subjects to presume the position of the point in the spatial smoothing map. Using the observed data, the models are estimated and their significance is evaluated by AIC. The model obtained in this paper is effective for explaining how a man recognizes the position of the point in the spatial smoothing map, and discussing the optimal level of smoothing of the spatial smoothing map.
