任何两个地理尺度之间的关系的一个简单的类型学是建立在定性比较各自的颗粒和范围。这种类型学适用于空间、时间和时空尺度。它描述了空间或时间中任何两个尺度之间的七种关系。这些基本关系产生一组169个不同的时空尺度关系，其中的一个子集描绘图解。如果有可能将过程或模式从一个尺度转换为另一个尺度，则可能需要同时应用多达四种缩放方法，这取决于关系。尺度方法可以分为粒度概括、粒度分解、范围外推或范围选择。这种类型学也可以提供一个框架，尺度之间的依赖关系的调查，以及尺度非平稳性的观察的参考方案。提供的可能性，任何关系，形成一个不相交的层次，无论是在空间或时间是一个关系，本质上是独立的尺度。然而，这种类型的使用取决于一些因素，它是作为一种工具，而不是解决方案，规模问题。
A simple typology of relations between any two geographical scales is established by qualitatively comparing their respective grains and extents. This typology is applied to spatial, temporal, and spatiotemporal scales. It describes seven relations between any two scales in either space or time. These basic relations yield a set of 169 qualitatively different spatiotemporal scale relations, a subset of which is portrayed diagrammatically. If it is possible to transform processes or patterns from one scale in the relation to the other, up to four scaling methods may need to be simultaneously applied, depending on the relation. Scaling methods might be classified as forms of grain generalization, grain decomposition, extent extrapolation, or extent selection. This typology may also provide a framework for investigations of dependencies between scales, as well as a reference scheme for observations of scale nonstationarity. The possibility is offered that any relation that forms a nonintersecting hierarchy in either space or time is a relation between essentially independent scales. However, the use of this typology is contingent on a number of factors, and it is offered as a tool, rather than a solution, for problems of scale.
