Abstract
The application of geographic information system has rapidly developed. However, due to the difficulty of data conversion among different spatial scales and areal units, application of census geography has been seriously limited, and therefore, a geographic data conversion model to solve the so-called Modifiable Areal Unit Problem (MAUP) is critically needed. The purpose of this paper is to develop a spatial data conversion model for the application of census geography. By means of address matching, census data in polygon system are converted into point-based (address-based) system. And then, census data can be grouped into different spatial units to meet requirements of different applications while a certain level of accuracy is achieved. In addition, a case study of Taipei MRT system is conducted to demonstrate possible applications of the developed model.
