Top-down/Bird's eye/Satellite view terrain stamp collections (including mountains, cliffs, hills, etc). For examples see WOTC maps or Google Maps satellite view for inspiration.
Current stamps for terrain seem to be more of an isometric view and for creating large top-down world maps this can result in unused space behind terrain and ambiguity on where terrain actually starts and ends.
It would also just be great to see as a style option.
Thanks!
