Spatial Analyst 类概述 (arcpy.sa)

Spatial Analyst 类主要用于定义 Spatial Analyst 工具的参数，根据所选参数类型（例如，邻域类型）的不同，可能会包含数量不等的实际参数，或者参数中的条目数何时会根据具体的情况（例如重分类表）发生变化。通过使用参数的类，可以访问并通过编程来更改参数中的任何单独条目。

下表列出了 Spatial Analyst 类的常规功能组。定义参数各选项的类被归到同一组。

Fuzzy Membership	Defines the membership function for fuzzy logic analysis
Horizontal Factor	Identifies the horizontal factor for the Path Distance tool
Kriging Models	Develops the model for creating surfaces with kriging
Neighborhood	Defines the input neighborhood for a series of tools
Overlay	Creates the input tables for the Weighted Overlay and Weighted Sum tools
Radius	Identifies a radius for the IDW and kriging tools
Remap	Defines various remap tables used in reclassification
Time	Identifies the time interval to use in the solar radiation tools
Topo Input	Defines the input to the Topo To Raster tool.
Vertical Factor	Identifies the vertical factor for the Path Distance tool.
