A Review on the Methodology of Scaling with Geo-Data
地理数据尺度转换方法研究进展

The ability to change scale is one of the main development topics in GIS and RS. GIS and image processing systems have offered some tools for multi-scale approaches. But the capabilities are limited. Scaling of multi-scale Geo-data is one of the suitable methods to deal with this problem. In this paper, the detailed review was done by comparing different methods in different research areas. Areal interpolation is the most important way to solve the scaling problems in GISci. And sociologists and economists have developed the small area statistics to solve the problem of the changing of the statistical units. And the review shows that there are some similar principles in different methodologies, and each one has its special pivots.
