A Probe into the Modeling Method for GIS-based Urban Land Grading Information System

摘要：

Determination of the grading method, sizing of the grading unit and generation of the weight values of the grading factors are the key links of the construction of the GIS-based urban land grading information system, and there are different methods to determine these links. Selection of the modeling methods will determine whether the system building is reasonable or not. Based on the comparative analysis, this article will probe into and determine the relative optimal grading method, the relative optimal method to define the grid unit size and the relative optimal method to calculate the weight values of the factors.
