As you can see from that site, it groups Q drops by day. November 5, 2017 was a huge day for drops.
The pic you linked to is what I believe Q refers to as "the map" in his posts.
I've never been able to get "https://qanonposts.com/" to display data for me; possibly something in my firewall is blocking it.
Yes, that does look something like part of the "Q Maps" -- but, it was archived on "4plebs" -- which I'd never encountered before... As I noted, that page is a static image -- sans active links.
Every now and then I stumble upon sites where all the numeric links are active. They're loaded with info -- but, they're usually filled with strife and bickering, etc., as well.
