城市增长已被广泛研究，并开发了许多模型（特别是元胞自动机和基于代理的模型）。这些模型中的大多数依赖于地理空间的两种表示：栅格和矢量。这两种表示法各有优缺点。栅格模型实现起来更简单，需要的数据更少，这解释了它们的成功以及为什么大多数城市增长模型都基于这种表示。然而，它们不适合于微观动力学，例如建筑物的建造。为了达到这样的目标，基于矢量的空间表示是强制性的。然而，很少有矢量模型存在，没有一个是容易适应不同的案例研究。在本文中，我们建议使用一个简单的栅格模型，并将其调整为矢量表示的地理空间和过程，允许研究城市增长在细尺度。这两种模式已被验证的案例研究，关于城市的坎托，越南。
Urban growth has been widely studied and many models (in particular Cellular Automata and Agent-Based Models) have been developed. Most of these models rely on two representations of the geographic space: raster and vector. Both representations have their own strengths and drawbacks. The raster models are simpler to implement and require less data, which explains their success and why most of urban growth models are based on this representation. However, they are not adapted to microscopic dynamics such as, for example, the construction of buildings. To reach such goal, a vector-based representation of space is mandatory. However, very few vector models exist, and none of them is easily adaptable to different case studies. In this paper, we propose to use a simple raster model and to adapt it to a vector representation of the geographic space and processes allowing studying urban growth at fine scale. Both models have been validated by a case study concerning the city of Can Tho, Vietnam.
