Résumé
The Create Index Table tool produces a map index table from a series of feature classes. For example, this tool could produce a table of cities and counties in which a set of streets are located. You can embed this table as a surround element in an ArcGIS page layout.
Utilisation
The tool performs a union between the Input Features (in_index_features) and the Overlay Features (in_overlay_features). The output of the union is generalized by values chosen in the Join option of Overlay Features (in_overlay_features) and in the Feature Size Threshold Percentage (threshold) parameter.
Use a point, line, or polygon feature class as Input Features (in_index_features).
Use polygon feature classes as Overlay Features (in_overlay_features).
Select the attributes you want included in the resulting index data from Input Features (in_index_features).
You must convert annotation features to polygons using the Dissolve tool before you can index them.
Syntaxe
CreateIndexTable(in_index_features, index_fields, in_overlay_features, out_table, {threshold})| Paramètre | Explication | Type de données |
in_index_features | The feature class used to create a table that contains index data. | Feature Layer |
index_fields [index_fields,...] | The attribute fields that you want to include in the output table. Each unique combination of field values will result in a unique record in the output table. | Field |
in_overlay_features [[Overlay Features, {Field}, {Join}],...] | The features against which you want to index the Input Features (in_index_features) parameter. For example, if you want to show a grid cell in which a city is located, you can add the grid cell's feature class to this parameter. The Join value in this parameter controls whether multiple resulting matches are joined by a comma-separated list or if each successful match results in a new record in the output table. | Value Table |
out_table | The output table that will contain the resulting index data. | Table |
threshold (Facultatif) | The minimum size of a part of the index feature that will be included in the output table expressed as a percentage of the feature's total size (that is, length for lines and area for polygons). This parameter is used to prevent small portions of the index feature (for example, a small segment of a street located in a certain city) from being included in the output. For example, if you set the parameter value to 5, portions of a street line that are less than 5 percent of the line's total length will be ignored in the output. | Long |
Exemple de code
CreateIndexTable example (Python window)
The following Python window script demonstrates how to use the CreateIndexTable tool.
import arcpy
# set gp environment variables
arcpy.env.workspace="c:/data/Austin.gdb"
arcpy.env.overwriteOutput = True
arcpy.env.addOutputsToMap = False
# in_index_features parameter
roadL = "TopographicMap/RoadL"
roadLyr = "roadLayer"
# Create a fishnet to simulate a grid to use in the in_overlay_features parameter
overlayFeatures = "overlayFeatures"
overlayFeaturesLyr = "overlayFeatures_layer"
origin="-97.7500000098922 30.2499999994191"
yAxis="-97.7500000098922 40.2499999994191"
arcpy.CreateFishnet_management(overlayFeatures,origin, yAxis,"#","#","2","2","#","NO_LABELS",roadL,"POLYGON")
# add a field to the fishnet feature class and calc it
arcpy.AddField_management(overlayFeatures,"gridnumber","TEXT")
arcpy.CalculateField_management(overlayFeatures,"gridnumber","[OID]")
# add outputs to map for following operations
arcpy.env.addOutputsToMap = True
# Make Feature Layer for the in_index_features parameter
if arcpy.Exists(roadLyr) == False:
arcpy.MakeFeatureLayer_management(roadL, roadLyr)
# Make Feature Layer for the in_overlayFeatures parameter
if arcpy.Exists(overlayFeaturesLyr) == False:
arcpy.MakeFeatureLayer_management(overlayFeatures, overlayFeaturesLyr)
# output index table (created in the current workspace)
roadIndextable = "roadL_indextable"
# execute Create Index Table
arcpy.CreateIndexTable_production(roadLyr, "FCsubtype", overlayFeaturesLyr + " gridnumber true", roadIndextable, "10")
