ArcMap

将空间权重矩阵转换为表

描述

用于将二进制空间权重矩阵文件 (.swm) 转换为表。

插图

Swm 至 DBF 的转换
Swm 文件可能会转换为 .dbf 表并对其进行编辑。

使用方法

语法

arcpy.stats.ConvertSpatialWeightsMatrixtoTable(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。

Table

代码示例

ConvertSpatialWeightsMatrixtoTable 示例 1（Python 窗口）

以下 Python 窗口脚本演示了如何使用 ConvertSpatialWeightsMatrixtoTable 函数。

import arcpy
arcpy.env.workspace = "c:/data"
arcpy.ConvertSpatialWeightsMatrixtoTable_stats("euclidean6Neighs.swm", "euclidean6Neighs.dbf")
ConvertSpatialWeightsMatrixtoTable 示例 2（独立脚本）

以下独立 Python 脚本演示了如何使用 ConvertSpatialWeightsMatrixtoTable 功能。

# Create a Spatial Weights Matrix based on Network Data 
# Import system modules
import arcpy
# Set property to overwrite existing output
arcpy.env.overwriteOutput = True
# Local variables...
workspace = r"C:\Data\USCounties\US"
# 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")
