Label | Explanation | Data Type |
Input Spatial Weights Matrix File | The full pathname for the spatial weights matrix file (.swm) you want to convert. | File |
Output Table | A full pathname to the table you want to create. | Table |
Summary
Converts a binary spatial weights matrix file (.swm) to a table.
Illustration
Usage
This tool allows you to edit a spatial weights matrix file, if necessary:
- Create a spatial weights matrix file using the Generate Spatial Weights Matrix tool.
- Convert the resultant spatial weights matrix file to a table using this tool.
- Edit the table and modify the spatial relationships as desired.
- Use the Generate Spatial Weights Matrix tool to convert the modified table back to the binary spatial weights matrix file format.
Parameters
arcpy.stats.ConvertSpatialWeightsMatrixtoTable(Input_Spatial_Weights_Matrix_File, Output_Table)
Name | Explanation | Data Type |
Input_Spatial_Weights_Matrix_File | The full pathname for the spatial weights matrix file (.swm) you want to convert. | File |
Output_Table | A full pathname to the table you want to create. | Table |
Code sample
The following Python Window script demonstrates how to use the ConvertSpatialWeightsMatrixtoTable function.
import arcpy
arcpy.env.workspace = "c:/data"
arcpy.ConvertSpatialWeightsMatrixtoTable_stats("euclidean6Neighs.swm", "euclidean6Neighs.dbf")
The following stand-alone Python script demonstrates how to use the ConvertSpatialWeightsMatrixtoTable function.
# 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")
