GW is correct.
Camps apply and many are listed by name-description, but not location on the Burning Man 2019 theme camp list -
https://burningman.org/event/brc/2019-theme-camps/. Our BORG masters make the list hard to search.
Then Placement places many from that list and others not on the list and privately communicates their coordinates to the camp.
The camps may publish their location to unofficial lists from that private location as GW mentions.
Then the camps arrive on playa and check in with their BORG Placement placer. At that point they could be moved. That means what they sent to unofficial lists could be burnt toast.
Once every camp is actually placed Sunday gate, the internal BORG map is electronically updated to official. From my understanding that is what emergency services has. That would be about August 25.
Say camp Fancy Camp arrives and checks in with Placement on August 24. Fancy Camp: "Um, we requested 200' x 200' for 50 RVs and 200 people, so we got 100 DGS tickets, but we only have 3 people in tents because the dog ate our homework." Placement: "No problem, I'll call the other placers to fill in the space." So all of a sudden, camps get moved.
So there is not a real map until about August 25 or after.
After the event, the area is inspected for trash and the trash is logged on the official map of camps.
The BORG publishes a camp map with trash markings many months after the event.
So OP, your simple question is not as simple as you might think, unless you view it through the Alice in Wonderland looking glass. The system is designed for a measure of privacy on playa, flexibility, and with full transparency on trash left behind after the event.
Of course, I may be hallucinating, sure we have Placement on here...
