I also have a legend in the layout I would like to change according to the layer as well. How will I be able to do this? Make sure that your legend synchronizes with visible layers: JohannesLindner_0-1658746688101.png   Do you have a link to this documentation for editing and exporting layouts specifically as well? You can manipulate layouts with the arcpy.mp (mapping) module: Introduction to arcpy.mp—ArcGIS Pro | Documentation In the link's table of contents, expand the "Classes" tab to see the documentation for all classes of that module. Here, I used Layout, MapFrame, Map, Layer, and TextElement. ... View more

This also handles group layers, even nested ones:   from pathlib import Path def export_layout_for_each_layer(layer_list, layout, save_folder): save_folder = Path(save_folder) # turn all layers off for layer in layer_list: layer.visible = False # while there are still layers in the list while layer_list: # remove the first layer from the list and make it visible layer = layer_list.pop(0) layer.visible = True # special treatment for group layers if layer.isGroupLayer: # recursively call this function on its sub layers (this exports all the sub layers on their own export_layout_for_each_layer(layer.listLayers(), layout, save_folder) # make the sub layers visible (so we can export the group layer) and remove the sub layers from the master layer list (because we already exported them) for sub_layer in layer.listLayers(): layer_list.remove(sub_layer) sub_layer.visible = True # set title and export, then make layer invisible print(f"Exporting layout for {layer.name}") layout.listElements("TEXT_ELEMENT")[0].text = layer.name layout.exportToPDF(save_folder/f"{layer.name}.pdf") layer.visible = False # define your save location save_folder = Path(arcpy.env.workspace).parent # get the elements you need aprx = arcpy.mp.ArcGISProject("current") layout = aprx.listLayouts("Layout")[0] map_frame = layout.listElements('MAPFRAME_ELEMENT')[0] layers = map_frame.map.listLayers() # run it export_layout_for_each_layer(layers, layout, save_folder)   ...

  from pathlib import Path # define your save location save_folder = Path(arcpy.env.workspace).parent # 'C:/Users/xxx/Documents/ArcGIS/Projects/Testing' # get the elements you need aprx = arcpy.mp.ArcGISProject("current") layout = aprx.listLayouts("Layout")[0] title = layout.listElements("TEXT_ELEMENT")[0] map_frame = layout.listElements('MAPFRAME_ELEMENT')[0] layers = map_frame.map.listLayers() # turn off all layers for layer in layers: layer.visible = False # loop over layers save_folder = Path(save_folder) for layer in layers: print(f"Exporting layout for {layer.name}") layer.visible = True title.text = layer.name layout.exportToPDF(save_folder/f"{layer.name}.pdf") layer.visible = False     This assumes that you only have one text element (the title) and no group layers.   ...

Hello, I work on the evolution of a pond from old maps. First of all, I georeferenced all my maps on ArcGis Pro, I also manage to superimpose them together. My problem is: I want to create a simplified map showing the evolution of the pond from the old lines of the pond. To do this, I don't know if I have to cut out my pond, which is not a completely circular pond, or if there is another way. Does anyone have a solution and can explain it to me clearly? I am new to ArcGis Pro So you have georeferenced maps of your pond from different years and want to extract only the area around the pond? You can do it this way: scroll to your pond for each of your georeferenced raster: right click on the layer in the contents Data -> Export Raster JohannesLindner_0-1658402763023.png   In the Export Raster dialog, set the Clipping Geometry to "Current Display Extent" JohannesLindner_1-1658402804475.png   ...

@LCTechLogin  You should be able to do something like this:   // calculation attribute rule // field: LastGeometryEdit (Date) // triggers: Insert, Update // geometry changed if we're inserting a new feature or if the old and new geometry aren't equal var geometry_changed = $editcontext.editType == "INSERT" || !Equals(Geometry($originalfeature), Geometry($feature)) // if geometry changed, return current dtae and time, else return field value return IIf(geometry_changed, Now(), $feature.LastGeometryEdit)     This could also be somewhat used as workaround for the original idea. But of course, the rule will still fire if you edit an attribute, so there will be some perfomance hit, especially if you edit large chunks at once. var geometry_changed = $editcontext.editType == "INSERT" || !Equals(Geometry($originalfeature), Geometry($feature)) // no geometry edit? return the current field value if(!geometry_changed) { return $feature.WATERSHED } // your code (this will only get executed if geometry_changed is true) var fsPolyBoundary = ... var fsPoly = ... var loc = ... ... ... return name ...

So you want to do something like this? Click on Create Features, choose the point template Click into the map but instead of creating a new feature, the coordinates of an existing point are updated   This could be kinda possible (you'd end up with a feature without geometry, so you wouldn't see it on the map). But, questions: What's your use case? Why not use the edit tools to edit the existing point? How would you decide which existing point to edit? Coordinates as in numeric fields in the table or as in the actual point geometry? ... View more

Let's look at Josh's answer above you. What it does is the following: get an array of values define a function with which to filter this array. this function returns true if you want the value to stay in the array. we want a value to stay in the array if it is unequal to zero (!=0). but we also have to account for null values. that's what DefaultValue does: it returns the value if it is not null and returns a default value (0 in this case) if it is null. filter the array get the average of the filtered array   So, if we apply Josh's answer to your problem (and make the steps more obvious): // get an array of values var values = [$feature.Qrt1_2022, $feature.Qrt2_2022, $feature.Qrt3_2022, $feature.Qrt4_2022] // define a function that we use to filter the array // returns true (keep value) if value is not null and is unequal to 0 function drop_zero(value) { var non_null_value = DefaultValue(value, 0) // value is null? -> value = 0 return non_null_value != 0 } // filter the array var filtered_values = Filter(values, drop_zero) // return the average of the filtered array return Average(filtered_values) ...
