As keep add new post, it become impossible for slowly create beautiful travel map and work backward, instead, from each post that made what to show in geotag manner, just direct from the post add the geotag information and let them dynamically show in one dynamic generate page below.
So, it instantly provide and use map for search and found information. I think for all the future post, for those worth to mark geotag location will use and doing this way from now onward.
This should be the most handy way, save lot of time and focus on content development for that specific post only.
