Functionality:
A button to "Mark" the area currently visible on screen (i.e., the current map extent).
This area is automatically added to a background tracking layer (invisible or visible as needed).
Helps to avoid revisiting already marked areas.
Ability to mark a location as visited, for example, when updating building footprints or parcel extents.
Behavior:
Each time the user clicks the "Mark this area" button:
ArcGIS Pro captures the current map extent.
It saves this extent as a polygon feature in a dedicated tracking layer.
This layer can be used for:
Symbology (e.g., completed vs. pending zones),
Spatial queries (e.g., to see which areas still need coverage),
Export or reporting.
Optional Features:
Automatic timestamp (date when the area was marked).
User ID tracking (for multi-user environments).
A button to "Show/Hide Marked Areas" (to toggle visibility of the tracking layer).
