将空间权重矩阵转换为表

摘要

将二进制空间权重矩阵文件 (.swm) 转换为表文件。

插图

Swm to DBF conversion
Swm files may be converted to .dbf tables and edited.

用法

语法

ConvertSpatialWeightsMatrixtoTable_stats (Input_Spatial_Weights_Matrix_File, Output_Table)
参数说明数据类型
Input_Spatial_Weights_Matrix_File

要转换的空间权重矩阵文件 (.swm) 的完整路径名。

File
Output_Table

要创建的表的完整路径名。

代码示例

将空间权重矩阵转换为表示例（Python 窗口）

以下 Python 窗口脚本演示了“将空间权重矩阵转换为表”工具的使用方法。

import arcpy
arcpy.env.workspace = "c:/data"
arcpy.ConvertSpatialWeightsMatrixtoTable_stats("euclidean6Neighs.swm","euclidean6Neighs.dbf")
将空间权重矩阵转换为表示例（独立 Python 脚本）

以下独立 Python 脚本演示了“将空间权重矩阵转换为表”工具的使用方法。

# Create a Spatial Weights Matrix based on Network Data 

# Import system modules
import arcpy

# Set property to overwrite existing output
arcpy.arcpy.overwriteOutput = True

# Local variables...
workspace = r"C:\Data\USCounties\US"

try:
    # Set the current workspace (to avoid having to specify the full path to the feature classes each time)
    arcpy.env.workspace = workspace

    # Create Spatial Weights Matrix 
    # Process: Generate Spatial Weights Matrix... 
    swm = arcpy.GenerateSpatialWeightsMatrix_stats("USCounties.shp", "MYID",
                        "euclidean6Neighs.swm",
                        "K_NEAREST_NEIGHBORS",
                        "#", "#", "#", 6) 

    # Dump Spatial Weights to Database Table
    # Process: Convert Spatial Weights Matrix to Table...       
    dbf = arcpy.ConvertSpatialWeightsMatrixtoTable_stats("euclidean6Neighs.swm",
                        "euclidean6Neighs.dbf")

    # Now you can edit the spatial weights (add, subtract and alter
    # neighbors and weights)

    # Read weights from table back into Spatial Weights Matrix format
    # Process: Generate Spatial Weights Matrix... 
    swm = arcpy.GenerateSpatialWeightsMatrix_stats("USCounties.shp", "MYID",
                        "euclidean6Neighs.swm",
                        "CONVERT_TABLE",
                        "#", "#", "#",
                        "#", "#", "#",
                        "euclidean6Neighs.dbf") 

except arcpy.ExecuteError:
    # If an error occurred when running the tool, print out the error message.
    print(arcpy.GetMessages())
