If you want to delete everything in the map just select the first object in the list of added objects and then scroll down to the final object listed and whilst holding down shift select the bottom option. With this you will have every object in the scene selected and then a simple press of the delete key will quickly make a map devoid of anything (unless there is pre generated trees) to flatten the map simply set the radius to 100 and it should only take about a minute to flatten the whole map. All up it should only take a bit over a minute to make a completely blank map.
