Repetitive Tasks: Save a copy of APRX, Rename Copied APRX, Query a layer, Set scale of map frame

CiaraMarleneKeenan — Tue, 06 Aug 2024 21:13:41 GMT

Calling all Developers! I do NOT want to do something manually lol Or trying to do the least amount of repetitive tasks as possible.

I need a script that would allow me to

1. Save a copy of an APRX template

2. Rename the copied APRX x 50

3. Query a polygon layer based on a name field x 50

4. Set scale of map frame x ?

5. Pan to & center polygon feature in map frame x 50

Unfortunately, I am not able to use a map series for this particular project because there are too many different scales for the features to make the maps look nice. I need to make about 50 maps so the more I can do with python will be greatly appreciated.

Here is a little something to get you started.

Untested.

import arcpy import os template_aprx_path = r"C:\your\template.aprx" # Path to your APRX template output_folder = r"C:\output\folder" # Folder to save the copies polygon_layer_path = r"C:\path\to\your\polygon_layer" # Path to your polygon layer name_field = "Name" # Field used for querying map_frame_name = "Layers Map Frame" # Name of the map frame to modify scale = 50000 # Desired scale for the map frame # Ensure output folder exists if not os.path.exists(output_folder): os.makedirs(output_folder) # Create copies of the APRX template and process each for i in range(1, 51): # Loop 50 times # Define the new APRX file path new_aprx_path = os.path.join(output_folder, f"Project_{i}.aprx") # Copy the APRX template to the new file arcpy.management.Copy(template_aprx_path, new_aprx_path) # Open the APRX file aprx = arcpy.mp.ArcGISProject(new_aprx_path) # Get the map map_obj = aprx.listMaps()[0] # Get the map frame map_frame = map_obj.listLayers(map_frame_name)[0] # Query the polygon layer and process each feature with arcpy.da.SearchCursor(polygon_layer_path, [name_field]) as cursor: for row in cursor: feature_name = row[0] # Select the polygon feature based on the name arcpy.management.SelectLayerByAttribute(polygon_layer_path, "NEW_SELECTION", f"{name_field} = '{feature_name}'") # Get the selected feature's extent selected_features = arcpy.management.MakeFeatureLayer(polygon_layer_path, "temp_lyr", f"{name_field} = '{feature_name}'") extent = arcpy.Describe(selected_features).extent # Zoom polygon feature in the map frame map_frame.camera.setExtent(extent) map_frame.camera.scale = scale # Save changes aprx.save() # Release the APRX object del aprx print("Processing completed.")

Hi Tony,

I am getting this error...

Traceback (most recent call last):
File "<string>", line 30, in <module>
IndexError: list index out of range

Also am I supposed to put quotes around the map name on line 27?

Thank you.

The following code loops through the "CITY" field, processing each unique city. For each city, it creates a feature class in the geodatabase, zooms into that city's area, and generates a new .aprx file named after the city. I believe this code will do what you are asking. You may need to make adjustments to fit your specific requirements, hope it helps.

project.save() import arcpy import os # Define paths gdb_path = r"C:\your\template.gdb" # Path to your geodatabase location polygon_layer_path = r"C:\your\template.gdb\layer" Path to your polygon layer # Get the current project and map project = arcpy.mp.ArcGISProject("CURRENT") map = project.listMaps()[0] # Adjust if necessary to select the correct map lyt = project.listLayouts('Layout')[0] # Adjust if necessary to select the correct layout, THIS IS SUPPER IMPORTANT, IF YO DON'T CHANGE IT TO MATCH YOURS,THE CODE WILL NOT CREATE THE APRX. mf = lyt.listElements("MAPFRAME_ELEMENT", '*')[0] # Get the first map frame element # Make a feature layer from the feature class arcpy.management.MakeFeatureLayer(polygon_layer_path, "city_limits_layer") # Access the feature layer city_limits_layer = "city_limits_layer" # Get unique values from the CITY field city_names = set() with arcpy.da.SearchCursor(city_limits_layer, ["CITY"]) as cursor: for row in cursor: city_names.add(row[0]) # Loop through each unique city and create a feature class in the geodatabase for city_name in city_names: # Create a feature layer for the city arcpy.management.MakeFeatureLayer(polygon_layer_path, "temp_city_layer", f"\"CITY\" = '{city_name}'") # Define the path for the new feature class in the geodatabase city_feature_class = os.path.join(gdb_path, f"{city_name.replace(' ', '_')}_fc") # Copy the feature layer to the geodatabase arcpy.management.CopyFeatures("temp_city_layer", city_feature_class) # Add the feature class to the map map.addDataFromPath(city_feature_class) # Get the new layer from the map new_layer = map.listLayers(f"{city_name.replace(' ', '_')}_fc")[0] # Get extent using arcpy.Describe() desc = arcpy.Describe(new_layer) ext = desc.extent # Zoom to the extent of the layer mf.camera.setExtent(ext) # Set the scale to 1:24,000 mf.camera.scale = 24000 # Create a new project for each city new_project_path = os.path.join(r"C:|Tenp\CityLimits", f"{city_name.replace(' ', '_')}.aprx") # Folder to save the copies new_project = arcpy.mp.ArcGISProject("CURRENT") new_project.saveACopy(new_project_path) # Save the original project (optional) #project.save()
