Automatically exporting maps through layer toggle

CFrost

Hi, I have a list of layers that I want mapped.  the layers are a mix of raster / vector but the map extent is a global and consistent regardless of the layer.  The legend attributes are the same as well, just the legend title (name of layer) would need to change. 

Is there a way to automatically cycle through the list of layers turning one on at a time, updating legend name, and exporting this as a map?  Basically, the same as data driven pages but instead of cycling through various features and changing extents, the extent stays the same but the layers are changing.  

Any advise welcome!

You can do that with a little Python. A quick-and-dirty approach:

layout_name = "Layout"
locked_layers = ["World_Imagery"]  # these layers will not change visibility
export_folder = "N:/.../temp"

# get the layout, its map frame, and its legend
aprx = arcpy.mp.ArcGISProject("current")
layout = aprx.listLayouts(layout_name)[0]
mapframe = layout.listElements("MAPFRAME_ELEMENT")[0]
legend = layout.listElements("LEGEND_ELEMENT")[0]

# get the layers
layers = [
    layer
    for layer in mapframe.map.listLayers()
    if layer.name not in locked_layers
    and layer.supports("visible")
    and layer.name == layer.longName
    ]
# for each layer
for layer in layers:
    print(f"Exporting layer {layer.name}")
    # make all layers invisible
    for other_layer in layers:
            other_layer.visible = False
    # make the layer visible
    layer.visible = True
    # change the legend title
    legend.title = layer.name
    # export the layout
    layout.exportToPNG(f"{export_folder}/Export_Layer_{layer.name}.png")
