| Abstract: | Local Moran index and Getis-Ord local G are the mostly common indices used for the analysis of local spatial autocorrelation.The two indices are compared based on simulated space by designing several spatial congregation schemes and their characters in finding the local spatial autocorrelation are analyzed.It is concluded that Getis-Ord local G is better than local Moran index. |

| Keywords: | spatial statistics spatial autocorrelation local indices local Moran index Getis-Ord local G |
