Export multiple layers individually to image, same extent, arcgis pro

AA25 — Thu, 29 Feb 2024 10:32:02 GMT

In arcgis pro, I have a 5 polygons layers.

I'd like to export an image of each layer alone (5 images), without the other 4 layers being visible.

I would like the map extent to be identical for each exported image.

I would like the aspect ratio of the image to be 16:9.

Is there a way automate this export process?

The script below worked for me. Please check its safe for yourself. I accept no responsibility for its effects.

It exports layers in the "export" group based on "layout1" to images.

If there is a better way to do this, I would be interested to know. Thanks! 😊

import arcpy import os # Get the username of the current user to construct dynamic paths username = os.getlogin() # Construct the project path dynamically project_path = f"C:\\Users\\{username}\\Desktop\\project\\project.aprx" # Construct the export path dynamically export_path = f"C:\\Users\\{username}\\Desktop\\project\\export" if not os.path.exists(export_path): os.makedirs(export_path) # Load the ArcGIS Pro project aprx = arcpy.mp.ArcGISProject(project_path) # Obtain references to the specified layout and map layout = aprx.listLayouts("layout1")[0] map = aprx.listMaps("map1")[0] # Get the group layer named "export" within the map export_group_layer = None for lyr in map.listLayers(): if lyr.isGroupLayer and lyr.name == "export": export_group_layer = lyr break if export_group_layer is not None: # Iterate through each layer in the "export" group for layer in export_group_layer.listLayers(): # Make the current layer visible and all others in the group invisible for lyr in export_group_layer.listLayers(): lyr.visible = (lyr == layer) # Construct the export file name and path export_file_name = f"{layer.name}.png" export_file_path = os.path.join(export_path, export_file_name) # Export the layout to image layout.exportToPNG(export_file_path) print(f"Exported {layer.name} to {export_file_path}") else: print("Group layer 'export' not found in the specified map.")

Great @AA25 , you found it! I did some tests on my end, and was able to export separate images. (Extent is set through layout itself, I was unable to set it through code). Hope this helps as well.

import arcpy import os # Set the workspace arcpy.env.workspace = r"C:\Users\geete\Downloads\exported" # Set the map document aprx = arcpy.mp.ArcGISProject("CURRENT") map = aprx.listMaps("Map")[0] # Get the extent of the map #map_extent = map.defaultCamera.getExtent() # Create a new layout for exporting layout = aprx.listLayouts()[0] # Iterate through each layer in the map for layer in map.listLayers(): # Turn off all layers except the current one for lyr in map.listLayers(): if lyr == layer: lyr.visible = True else: lyr.visible = False # Set the extent of the layout map frame layout_map_frame = layout.listElements('MAPFRAME_ELEMENT')[0] # Define output PNG filename output_png = os.path.join(r"C:\Users\geete\Downloads\exported", f"{layer.name}.png") # Export the layout to PNG layout.exportToPNG(output_png, resolution=60) # Reset visibility of all layers for lyr in map.listLayers(): lyr.visible = True
