Retrieve Scale from All Maps

TheBobScript — Fri, 29 Oct 2021 01:23:12 GMT

I am able to get a list of all maps in a project (Project.Current.GetItems<MapProjectItem>()) and display a number of properties, like name, layers, spatial reference, etc. One thing I cannot seem to access is the current scale for each of these maps (MapProjectItem).

I would like to retrieve the scale for all of my maps in my project. I know you can retrieve the scale for an active map (MapView.Active.Camera.Scale), but how do I get the scale for a map that is not active? Can I retrieve the scale from each map without making it the active map in my project?

I don't see scale but to get the extent, this works:

protected override async void OnClick() { //Saving the project is needed to assure the // map definitions are in sync with the view extents await Project.Current.SaveAsync(); await QueuedTask.Run(() => { foreach (var mapdef in Project.Current.Items .OfType<MapProjectItem>() .Select(itm => itm.GetMap().GetDefinition())) { Trace.WriteLine(mapdef.DefaultExtent.ToJson()); } }); }

Hi Kirk - Thanks for taking the time to reply. I'll take a look at what you have shared and see if that helps with what I'm after.
