>>36443111the guy who did that map didn't do one for Platinum, but except from a few minor things in Nimbasa City and Castelia City, everything on that map has an equivalent on Gen4. Gen4 also has daily events like trainer rematches, ruins, roaming Pokemon, etc..On top of that, Platinum had gym leader rematches, a battle frontier (which no Gen5 game has) which was even made an entire island with several places and routes, and other content like the Underground, secret bases, the distortion world.
