| Outline of Final Research Achievements |
Spatial scale plays a critical role in spatial analysis. The concept of spatial scale is involved in any analytical method, and thus the results of analysis depends on spatial scale. However, since there does not exist a general representation of spatial scale, it is impossible to compare the results of spatial analysis between different methods. To resolve this problem, this study developed a general representation of spatial scale. Based on spatial smoothing, the results of analysis is represented as a continuous function of scale.
