The measurement of GIS Exploratory Spatial Data Analysis in the land price distribution information extraction was study in this paper. As it is very difficult to satisfy the two premises in the traditional statistics for land price samples, other methods should be sought for. The Exploratory Spatial Data Analysis (ESDA) has been set up on the mathematic basis, which has some spatial methods for land price distribution. Besides, a few samples should be needed and the spatial relationship has been considered. It can therefore be used to study the land price distribution. The actuality research of ESDA was expounded in a case of urban commercial land price by GIS Arc / Info 8.0 in this paper. First, its mathematic basis was described. Then the measurements of GIS Exploratory spatial Data Analysis were studied, which included the data structure research, full trend analysis, searching direction and so on. In the end, the GIS Exploratory Spatial Data Analysis measurement was investigated with the Kriging Analysis as an example. The error analysis indicates that, if the frequency distribution of the samples assumes Normal Q-Q Plots and the measurements are used properly, the result is acceptable.
