Effect of Grid Space Resolution on Historical Data Analysis
- Pp. 39-53 (15)Pei-Lun Lee and Hsin-Chun Liu
This article uses GIS technology to analyze the distribution characteristic of commemorative shrines and steles of the Song Dynasty. The findings show that for the highly discrete historical data, smaller grid is not better. The major distribution is in the southeast coastal administrative regions, and inland Chengdufu Lu and Jinghunan Lu. The hot spot analysis shows that Liangzhe Lu, Huainandong Lu, Jiangnanxi Lu, Guangnandong Lu and Chengdufu Lu have apparent hot zones of construction, and from the north Huainandong Lu to the south Liangzhe Lu, Jiangnandong Lu, Jiangnanxi Lu and Fujian Lu form an apparent belt. The records of commemorative shrines and steles show that Emperor Ningzong of Song has the maximum 75 units, and Emperor Yingzong of Song has the minimum 1 unit. It may be related to the length of reign. In terms of space, there was no obvious location characteristic of distribution in various emperors' reigns in the Northern Song Dynasty, but the major distribution was in the south administrative regions in the Southern Song Dynasty. The results of this study can be provided for history researchers to discuss the historical background and space-time characteristics of the hot zone of construction.
