*Create an amplified map on Minecraft (PC version)
*After you have made the world and found a place set the spawnpoint to the place you would like to copy by doing /spawnpoint in game.
*Go into MCEDIT and look for the map. (open your world and click on level.dat)
*select a region that is 156x156 (256 length and width )
*copy the region and save it.
go into a minecraft pocket edition map by creating a map on minecraft pocket edition, logging on to Iexplorer, and taking out the map. After doing this, go to MCEDIT and look for the map on your desktop or wherever you put the mcpe map.
*open the mcpe map and flatten it out to bedrock.
*after you are done with that, paste your map from the minecraft PC version by using the button import.
once you are done pasting your map from the PC version into the PE version, you can replace the white wool with air using the replacement option.
After that, save the level and drag your world from PE back into it's original folder from Iexplorer. (minecraft worlds)
Your map should work.
If you have any trouble making an amplified map, please let me know...
