Résumé
Returns a list of Grid objects in a specified feature dataset.
Discussion
Grids created with the Make Grids And Graticules Layer geoprocessing tool or Grids and Graticules Designer are stored in a feature dataset within a workspace. ListGrids returns a list of Grid objects that are stored in the specified feature dataset.
Syntaxe
ListGrids (feature_dataset, {wildcard})| Paramètre | Explication | Type de données |
feature_dataset | The path to the feature dataset that contains Grid objects. | String |
wildcard | The wildcard limits the results returned. If no wildcard is specified, all values are returned. | String |
Valeur renvoyée
| Type de données | Explication |
| String | A list of Grid objects |
Exemple de code
ListGrids example 1
This sample lists the Grid objects within a specific dataset.
import arcpy
import arcpyproduction
# Check out Production Mapping license
arcpy.CheckOutExtension("foundation")
# List Grid objects in the Grids dataset
arcpyproduction.mapping.ListGrids(r"C:\Tutorials\CartographicProduction\Austin.gdb\Grids")
# Check in extension
arcpy.CheckInExtension('foundation')
ListGrids example 2
The following script will get the group layer of a grid and add it to current map document as a group layer.
import arcpy
import arcpyproduction
# Check out Production Mapping extension
arcpy.CheckOutExtension('foundation')
# Set the grid workspace
grid_dataset = r"C:\Project\Grids.gdb\WGS84"
# Get the list of grids in the workspace that has name area1
lstGrids = arcpyproduction.mapping.ListGrids(grid_dataset, "area1")
# Get the layer from the grid object in the grid list
grid_layer = lstGrids[0].layer
# Access the current mxd and the first data frame in the mxd
mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd)
# Add the grid group layer as the topmost layer in the first data frame
arcpy.mapping.AddLayer(df[0], grid_layer, "TOP")
# Save the mxd
mxd.save()
# Check in extension
arcpy.CheckInExtension('foundation')
